This Tooling Standards manual is for reference purposes only. Van-Rob is a supplier of a wide variety of stamped components and assemblies to a wide range of customers. Our deliverable is to have our supply base deliver tools that will provide the required quality of component, on time at a competitive price.

Given the broad scope of business we have categorized the tool build requirement in to three categories as a guideline.

It is of the utmost importance that you as a supplier communicate which category is applicable at the time of method development and quotation.

Category “A”

Exotic materials, high volume, large bed size, close tolerance, transfer, and high tonnage – the requirement is to follow the tooling standards.

Category “B”

Typical material cold rolled, hot rolled, non-coated, coated, typical open tolerance, high volume, and all presses - the requirement is that the tooling standards are reference only, and to be discussed at quotation.

Category “C”

Low volume any material – the requirement is that the tooling standards are reference only and method planning and tool build will be discussed at quotation.

2.0 General

2.1. Scope 2.1.1. It is the intention of Van Rob to standardize the global construction of all tooling.

Through strict adherence to these procedure and strong management of new die builds, Van-Rob will reduce overall tooling costs, increase die quality and generate a new standard.

2.1.2. Van Rob will ensure that all vendors sourced to produce tooling strictly adhere to the following standards and if cost reductions merit a deviation to the standards to meet budget shortfalls, written approval shall be requested & implemented from Van Rob Tooling Manager, Program Manager and the receiving Plant Manager prior to sourcing. (Ref., 2.5.2, 2.6.6)

2.2. Commercial Terms

2.2.1. Commercial terms as per customer Agreement and Purchase Order.

2.3. Request For Quote (RFQ) 2.3.1. Van-Rob will provide the required documentation consisting of math model, Part

Drawings, RFQ, and all necessary information (e.g. press specifications, etc.) in order to initiate the quotation process. (If the Vendor requires additional information they shall request within 3 days. All documents, math data, and any additional information provided are confidential.

2.3.2. The vendor shall respond to the RFQ as per contract, unless otherwise specified. 2.3.3. Due to timing constraints, the RFQ may be presented without final GD&T. Van-Rob

reserves the right to, and will replace this print or mark-up with an updated print. If the new print contains dimension and/or tolerance changes which affect the price, the tooling supplier shall submit the cost impacts in writing for approval by Van-Rob within 3 days.

2.3.4. If a re-quote is required, only incremental price changes will be accepted. The re-quote will provide a list of items that have changed and their price impact on the program.

2.4. Quotation Submission

A quotation shall include: 2.4.1. A complete description of the product offered 2.4.2. A concept process layout of the product offered. 2.4.3. Blank size (transfer tool) or strip width with progression (progressive die). 2.4.4. Lead time for tool build, tool run-off date, as per VR tool timeline requirements 2.4.5. Detailed cost break-down and total cost of the product offered. 2.4.6. A list containing deviations to any items in this document.


PROCEDURE # E234


Page | 5

2.4.7. Where possible, estimated tonnage calculation for the product offered, preferably for each station.

2.4.8. Any deviation requests from the Global Tooling Standards must clearly explained in writing on quote and may affect sourcing decisions.

2.4.9. Initial supporting simulations of the method plan for feasibility which will be reviewed by the sourcing team.

Responsibility

2.5.1. The Tooling Coordinator is responsible for ensuring that the Van-Rob Global Tooling Standards are met during Design, Construction and Plant Commissioning.

2.5.2. Any deviation requests from the Global Tooling Standards must be agreed, documented and signed by the Tooling Coordinator, Program Manager & Receiving Plant Representative. (Ref., 2.1.2, 2.6.6)

2.5.3. All dies must be warranted for quality and craftsmanship for a minimum of 50,000 strokes during normal full automatic production. In the event a die should fail prior to the end of the warranty period, Van-Rob will document by picture and strip/station samples all reasons for the failure. A warranty claim will be submitted to the vendor with all supporting information if the Vendor is found to be responsible.

2.6. Requirements, Project Timing & Remarks 2.6.1. Any delay to the program once initiated must be communicated to the Tooling

Coordinator or Tooling Manager immediately. 2.6.2. Bi-weekly tooling progress reports (Tooling Information Sheet E0087) are to be issued

to Van-Rob Inc. in the format supplied by Van-Rob Inc. These reports are due as standard on close of business, every other Wednesday, starting with the second week of any calendar year. It is critical and mandatory that all Vendors now submit these (E0087) Tooling Information Sheets as outlined. The timelines at Van-Rob are now logged and linked to master timing and payment schedules. Failure to provide as scheduled will ultimately affect Supplier Rating System and Payment Procurement. Comments section of Milestone & Timeline section is where Vendor must record explanations of delay to target Milestones. Van-Rob reserves the right to request more frequent progress reports if the schedule is being scrutinized. (Ref., 2.6.2, 2.7.3, 2.7.6)

2.6.3. If it is the intention of the Vendor to source out the tool build to another location or company other than the agreed, Van-Rob must be informed in writing and in agreement with the change. Tooling Coordinator, Program Manager & Buyer must be informed. Even with Van-Rob’s agreement for such arrangement, the initial contracted Vendor by Van-Rob is held responsible for all tooling being built.

2.6.4. Variation from the original proposal must be communicated via a revised or amended purchase order.


PROCEDURE # E234

2.6.5. Hurdles are opportunities to excel. Our expertise at Van-Rob Inc. is freely offered to help and apply new measures to master complex situations.

2.6.6. Authorization any and all changes to the specification must be requested in writing by the vendor and approved in writing before proceeding with the change. Deviations or verbal instructions resulting in failure to produce parts to drawing standards and submission dates will not be acknowledged. The integrity of the program is based on the tool source designing and building a die to produce parts to print in the timing allocated at PO receipt. (Ref., 2.1.2, 2.5.2)

2.6.7. The Vendor must have the strip layout and tool design approved by Van-Rob Inc. via a tool design review meeting prior to tool build start. Stock width, progression, material thickness is to be identified on strip layout. Press size, window requirements, shut height, die height, approximate tonnage required, feed direction, scrap issues and part exit verification should also be addressed as standard. At no time does die design approval, alleviate the vendor of full responsibility for the function, performance and serviceability of the die. Simulations have to be provided and approved by VR. CAD level also has to be identified.

2.6.8. Prior to design approval the Vendor must provide calculated tonnage requirements for the product. The calculated tonnage must not exceed 80% of the press peak rated tonnage for the intended production press. If any variation is noted it needs to be communicated and approved and if not it is the vendor’s responsibility not to exceed the press tonnage at the buy off facility.

2.6.9. All designs are to have a separate perishable detail Bill of Material including summary for all standard punches, pilots & bushings, Nitrogen, etc. This separate Perishable Bill of material must have in Title Block, the Van-Rob Code, Customer Part number, Supplier Job number & Ordering information with supplier contact information. Non-standard punches, and bushings will have all ordering information and a detailed drawing attached. All tools to be supplied with one spare set of punches, bushings. All pilots do not require a full set however must provide one spare for each separate design implemented. (example if there are 7 identical pilots then 1 must be provided as spare) In situations where it is more feasible & cost effective to make a die section with perhaps 3 or 4 congested piercing rather than 3 or 4 Machined shaped bushings, then it is understood that a spare replacement die section is to be also provided

2.7.0. A full file on CD/DVD with all final developed die documentation including wire files, and CNC cutter paths or any information required for the accurate reproduction of all details delivered to the Tooling Coordinator. The formed strip or parts must be also provided on a separate clearly labeled level in the design. All designs must have a complete accurate Bill of Material. A second copy on CD/DVD is to be delivered to the Corporate Tooling Manager for the Corporate Library. Failure to do so will block impeding payment procurement. (Ref., 2.7.0, 3.1.3, 3.1.6)

Attention: Corporate Tooling Manager Van-Rob Corporate Centre, 200 Vandorf Sideroad, Aurora Ontario, L4G 0A2


PROCEDURE # E234

2.7.1. Sample submissions require Light Scans or CMM layouts of 3 parts showing capability and dimensional tolerance compliance. In the case of more than 1 up dies 3 sets of parts from each hand or cavity will be submitted and labeled as such.

2.7.2. Van-Rob Inc. enters into each tooling build with the acknowledgement that at certain times issues arise due to unforeseen circumstances. Even in these cases, if these circumstances do affect tooling performance, Van Rob does not accept that this gives the tool designer or tool shop the right to demand full payment until the die produces parts to print at a run @ rate and quantities acceptable as per our customer requirements to Van-Rob Inc. Press time will be given within a 90 day time period to prove out tool performance. Tool performance has to reach a press performance of 70%OEE

2.7.3. It is the responsibility of the tool source to ensure that adequate lead-time is given for tryout material. This information is to be provided to the assigned Tooling Coordinator in writing via properly filled out E0087 Tooling Information Sheet. (Ref., 2.6.2, 2.7.3, 2.7.6)

2.7.4. At all times the tool designs are proprietary to Van-Rob Inc. and should not (in total or part) be given to another company or duplicated without written approval of the CME Manager.

2.7.5. Any requests for information of tooling being built for Van-Rob Inc., regardless of origin, must be redirected to Van-Rob Tooling Coordinator.

2.7.6. Part simulation will be required and submitted to Van-Rob as proof of due diligence. It is Van-Robs intension to ensure that the process meets the design requirements and mitigates the risk of the design. With the submission of the simulation does not remove the design responsibility from the vendor. Sample of the simulation will be required in the E0087 Tooling information sheet. (Ref., 2.6.2, 2.7.3, 2.7.6)

3.0 Die Design and Construction Standards

3.1. Tool Design Drawings and Criteria

3.1.0 All Dies are to be designed and built to metric standards. 3.1.1. Use standard die components whenever possible along with a detailed description of

manufacture and ordering requirements. All purchased components must be Metric including Die Pins, Lifters Punches & Bushings.

3.1.2. Use of purchased items such as Standard Lifter Inc., are recommended to aid in reducing die build costs. Any products being used will be discussed at Die Review stage prior to implementation into tooling in the event of any possible ban by VR of that particular product due to quality or reliability concerns.

3.1.3. All designs must be in CAD format acceptable to Van-Rob. Van-Rob Cad preference for tooling drawings is both the Native Design Software and Parasolid. All tool drawings are to be on CD (2 full copies required). (Ref., 2.7.0, 3.1.3, 3.1.6.)

3.1.4. For any part/s that will require destructive testing in production, an additional pierce will be required in the scrap of the part to save the stamping from testing.


PROCEDURE # E234


Page | 8

3.1.5. All Pierce hole diameters for weld nuts will be set to constant size on all dies. This will ensure that all weld cells will have identical electron pin locator diameters in production thereby reducing inventory and downtime.

3.1.6. Final tool designs will reflect the finished die when submitted. Any changes occurring from original will be documented for reference. Failure to provide such accurate, updated designs causes downtime and unnecessary costs in Plant Production and will lead to possible Vendor removal from Van-Rob Approved Supplier List (A.S.L.) Title blocks will appear in the lower RH side of each design page with detailed parts list above it. (Ref., 2.7.0, 3.1.3, 3.1.6)

3.1.7. Title block will contain all of following pertinent information on each page of design: Van-Rob Code or VR Part #, Customer part #, Cad File Number, Material Thickness & type of Material, Required Tonnage, Progression, Strip Width, Pitch if Transfer and Vendor Name and Job Number and Date.

3.1.8. The outline of the actual strip as it would look at various stations must be shown and also be detailed drawn on a separate level so it may be removed. Progression and Strip Width dimensions must be noted on this level in millimeters.

3.1.9. Van Rob requires a strip layout for pre-approval with each station layout. 3.1.10. Design will reflect front to back and left to right. Any symmetrically opposite die

sections will be assigned different detail numbers and will be designed in such a manor to prevent miss placement.

3.1.11. Designs will show parallel locations to assist in defining scrap removal system requirements as correctly positioned on the press bolster & ram. The width or space between the parallels, where scrap is produced, should be a minimum of 150mm and a maximum of 300mm. The height of distance between the sub-plate and the die shoe should not be less than 130mm for progressive dies to aid in safe scrap exiting from dies. If these dimensions cannot be met, approval from Van-Rob Inc., Tooling Coordinator and Plant designate is required.

3.1.12. We will be looking to see that the die shows good balance in tonnage and different cutting punch heights or shear angles. Estimated tonnage per station should be labeled below each station in strip layouts and completed die designs.

3.1.13. Standard punch, bushing and pilots to have ordering information. 3.1.14. Non-standard punches & bushings or any standard, with even the slightest

modification, must have ordering information and detailed drawing. 3.1.15. Any wire cut sections; vendor must show them in full detail to ease the manufacture of

spares. This is to include all screw and dowel locations to ensure perfect accurate replacement of original sections.

3.1.16. Die should be designed to minimize strip distortion in all areas of pilots and carrier strips.

3.1.17. The stock strip development must minimize material usage, while maintaining good balance for maximum strip strength through the die.

3.1.18. Start lines should be located in the die as a 1.5mm groove, painted Red, ground into guide rail or die section so as to avoid partial piercing, trimming, forming which could damage the die and plan if possible to not leave behind any scrap. If this occurs then


PROCEDURE # E234

a sample of scrap must be bolted to shoe on operator side & painted yellow. A note must highlight where to look for this scrap in tool when starting new coil.

3.1.19. All die design to show location of bottoming marker in draw die and re-strike for set up. Type of marker for Vendor to purchase is available from Tooling Coordinator. Location for marker is to be determined at strip layout review.

Provision must be given on the die design for engrav ing customer tooling identification onto the die as per customer specific requirement e.g. GM – VTAM. These markings are permanent and must be present prior to the die delivery.

3.2. Materials

3.2.1. Materials are to be as specified unless pre-approved by Van Rob. i. Generally the following is the base, ii. Die steels - D2 iii. Trim Punches – A2 iv. Form punches - D2 v.

3.3. Standard die sets and cast die sets criteria

3.3.1. Cast member and material will be a requirement on all die design reviews however will

remain the responsibility of the Vendor to ensure that the materials meet the design requirements of the tool. All Supplied information is intended as reference for the design and does not make Van-Rob responsible for the structural integrity of the tool design.

3.3.2. Any Access cores to be made as large as possible while still maintaining casting integrity.

3.3.3. Cavities in the top and bottom shoe to have minimum 50 mm core holes to facilitate the addition of air/electrical lines.

3.3.10. All dies are to contain “Plug & Play” sensor outfitting for die protection. All of the required sensors, wiring & distribution boxes to be mounted and stay with the tool when stored are to be purchased and furnished fully & correctly operational prior to shipping from Vendor. A standard trigger is to be used in conjunction with micro switch and is to enter into the materials edge by 0.200”. The angle on the trailing edge of the trigger is to have clearance enough to allow strip to go beyond progression by 0.30mm without activating micro-switch. Vendor supplies any and ALL sensors for tooling including transfer fingers sensors for part presence, antibuckle strip sensors and part-off sensors. Each Plant specifies the type of sensors required.

3.3.11. Edge lifters and stock lifters are to be made a standard diameter or width. The same construction method is to be used for all stock lifters, edge lifters and bar lifters. All lifters are to be easily removable and easily accessible within the die. All lifters must have tapped holes in part to aid in removal. (Purchased lifters preferred). All lifters to have threaded holes for removal with slide hammer. All lifter keeper blocks to be deeper than pilot lifter locator. All lifters to be in hardened sleeves or sections.

3.3.12. When a stock lifter can be removed from a die section without the need to remove any other ancillary pieces mounted to the top of the die section, it is acceptable to use a standard mold pin as the lifter.

3.3.13. All dies to contain a 1 piece, hardened and ground stock rail on the micro-switch side of the strip. This stock rail can be made of O1 ground stock, up to 1”x2”x10”. Rail dowels should be a tight fit in the rail and a slip fit in the die steel for easy removal. Entrance to stock guides to be chamfered and offset to ease coil feed. Stock support shelf to be longer than guides whenever possible to ease coil feed.

Cast thickness under pierce horns 50mm

PROCEDURE # E234


Page | 12

3.3.14. Steel mill specs though improving, still allow for camber in material. To translate the specs to stock guides equates to approximately 0.08mm (0.003” per inch). Provision should be made for camber in the stock guides as per good tool-making practices.

3.3.15. All die sizes, upper weight, lower weight, nitro-pressure and operation # to be stamped on operator side of tool on die surface. VR die identification plate and # E0019 must be stamped and attached to die shoe surface. Procedure E234 available from Tooling Coordinator outlines criteria for tagging. It is the Suppliers responsibility to furnish die with proper tagging and supply clear pictures through #E0087 Tooling Information Sheet to Tooling Coordinator.

3.3.16. Thread for jack-screws are to be placed in all sections (preferably near on opposite sides of dowel pins).

3.3.17. NO blind holes behind dowel pins are allowed unless completely unavoidable. To be agreed upon at sign off. If agreed at Design review a second unused set of reamed holes must be furnished into the design for possible use.

3.3.18. NO stripper bolts are to be used. 3.3.19. All sub-plates and strippers must have tapped holes for easy removal and lifting. 3.3.20. Guide rails must have tapped holes for jackscrews and edges to be chamfered. 3.3.21. Weldments and parallels, slots and QDC blocks must be chamfered. The 3/16 min.

chamfer to be on the bottom of the weldment. 3.3.22. Slug clearance in the die shoe shall be sufficient to ensure that slugs will fall freely

through, this includes pilot holes. 3.3.23. All spring hole pockets and sub-plate pockets in lower die have drain holes through

die to allow coolant and oil run off. 3.3.24. Air escape grooves must be ground in pins and bushings as required. All pin holes

must be machined through. 3.3.25. Offset one guide pin by minimum 6.00mm or ensure one guide pin is of a larger

diameter (Minimum 6.00) to prevent die assembly in reverse. Where die comprises of more than one die-set, all die sets will have this feature.

3.3.26. Die set to be painted customer specific colour, paint can be purchased at Acklands-Grainger Inc. to be visible from front and rear of die. Required colour will be specified to Supplier through Tooling Coordinator.

3.3.27. All Dies will be built to metric standards. 3.3.28. Dies must be built in such a manner that sections cannot be installed backwards or in

a mirror image position. All section should be reviewed for mistake proofing.

3.4. Parts, Scrap and Safety All scrap chutes to be screwed to the die shoe and never welded.

3.4.1. All chutes must be wide enough to transport free falling slugs without binding to required scrap troughs or bolster scrap openings. Scrap must not be able to accumulate on bolster.

3.4.2. All scrap to be avoided in areas where the finished part is dropped. No mixing of scrap and finished parts.

3.4.3. Die protection is to be discussed at die review with plant personnel. e.g. Manual operation –Supplier is responsible to purchase and supply all required sensors..


PROCEDURE # E234


Page | 13

3.4.4. All dies require scrap removal discussion at die review. It is the responsibility of the vendor to supply Van Rob approved scrap chutes and mountings to enable scrap to be removed from the die area onto a scrap system.

3.4.5. Scrap tray design should be part of die design. Distance between parallels shall be set in design that suits that standard; exceptions shall be justified for cause of non-standard gap. Overlay of bolster and scrap drops to troughs and pit openings shall be provided and reviewed at Die Design Review.

3.4.6. All scrap to be less than 300mm (12”) maximum. Every effort should be made to reduce scrap size. Scrap cutters are not to be as first choice used as method to reduce scrap size. Additional punches reducing scrap size is first choice processing.

3.4.7. Parts must fall freely when cut off. Any parts blanked through shall have enough area around part to allow for effective ejection of part from die area.

3.4.8. Button retainers and die buttons should be “mistake proofed” whenever possible to prevent putting bushings into wrong retainer holes.

3.4.9. Punch retainers and punches should be “mistake proofed” whenever possible to prevent putting punches into wrong retainer holes.

3.4.10. Air blow off is not acceptable, nor permitted in Van-Rob facilities. 3.4.11. Parts and scrap shall not be mixed as they are discharged from the die. 3.4.12. Strip advance is not permitted to be used as a method of part ejection from die.

All scrap chutes will not extend past the die shoe when in storage.


PROCEDURE # E234

3.5. Punches, Bushings, Cams and Die sections 3.5.1. The standard locating method of pierce punches in a hardened non ball lock holder is

to have a flat, ground onto the head of the punch and rectangle machined into the back of the holder that picks up the flat on the punch and provides clearance for the remainder of the punch head. No dowels are to be used.

3.5.2. Heavy-duty ball lock retainers are the only acceptable ball lock retainers when used. 3.5.3. Pierce and trim punches are to contain oil breakers/ slug ejectors. These are to be

made from a standard ejector pin backed up by a spring and set screw in the back of the punch. The same construction will be used on strippers.

Note: Vlier shedders are not acceptable 3.5.4. All cam section should be keyed to the die shoe. Avoid pocketing to save on cost. 3.5.5. For blank punches requiring heels, when a separate block of steel is used to make the

punch, then a proper heel is required before any cutting initiates. 3.5.6. For cutting punches and dies the following standard clearance guidelines apply

i. For steel up to 2.5mm (0.100”) clearance is 8%, per side. ii. For steel from 2.5mm (0.100”) to 6.35 (0.250”) clearances is 10%, per side. iii. For steel material over 6.35mm (0.250”) is 12%, per side. iv. In Die Review Meeting cutting clearance per material and application will be

thoroughly discussed and agreed upon. 3.5.7. For heel blocks required on form punches, the dimensional proportions are such that

the length or depth of the heel block should be equal plus a minimum of 12.0mm longer, than the height of the block. When the form punches cannot heel against a heel block, then the punch is to be keyed at the back and the punch is to use the same ratio as previously mentioned heel blocks.

3.5.8. Backing plates are to be screwed to the holder and the punch coming through the holder and fastening to the back plate, leaving the heads of the SHCS protruding from the back of the backing plate. Clearance is to be provided in the die shoe for the heads of the screws. The holder is to be screwed to the die shoe leaving the clearance hole and counter-bore holder.

3.5.9. The standard taper in wire cutting is ½ degree back taper to the bottom of the section. NO reclaimed punches unless approved in Die Design Review Meeting.

3.5.10. For a standard cam slide construction the sliding punch holder is to be a solid, hardened and ground block, riding in 5 piece construction base, being driven by a 4140 driver having hardened and ground O1 wear pads installed where contact will be made on slide and heel block. Wear pads on heel blocks are to be pocketed into blocks on thrust side only. All mating surfaces between slides, driver, heel and base are to have grease grooves machined or ground into them.

3.5.11. The two typical methods used for cam slide returns are: i. The first method is the buried nitrogen cylinder contained within the base of the

slide unit. This must also incorporate a positive return using cam plates mounted on the outsides of the driver and pins mounted on the outside of the slide.


PROCEDURE # E234


Page | 15

ii. Positive mechanical cam returns should be used as a preference. If not a limit switch as per die protection system standards shall be used, to ensure cam return.

NOTE: Stripping force should follow tool-making guidelines and springs used in stripping should be sized as per spring guidelines. Account should be taken for, Free length, Pre-load, effective spring stripping pressure and total travel. Effective stripping pressure is not compressed force.

3.5.12. All aerial cams are to be equipped with a positive return method. Aerial cams are to be used as a last choice, when all other pierce or form options are unavailable.

3.5.13. All forms must be coined or set for springback limiting. No free wipe by forms is allowed.

3.5.14. All form stations that are to be coated will be addressed at die design review. It is the responsibility of the tool source with the co-operation of VR to decide on best coating for application. Any coating that shows signs of degradation due to poor design will be the responsibility of the tool shop to replace or recoat. To eliminate cracks in blocks due to heat treating, no sharp corners are allowed unless it is a cutting edge.

3.5.15. Panel parts that run in transfer presses using pick and place to have a minimum loading and unloading clearance of 12.0mm between any cam while in the open position.

clearance in the stripper. 3.5.19. All punch S.B.R’s to be kept to a minimum (stripper to have 2.5mm land) 3.5.20. All punches, die sections, keepers, strippers, etc.; must be chamfered on all non-

cutting edges. 3.5.21. All die sections, punches, holders and components must be stamped and identified to

ensure fool-proofing and proper assembly. 3.5.22. Screw holes are to be counter bored deep enough to maximize die life on punches

and die sections. 3.5.23. If the die has a changeover, detailed pictures and instructions and poka-yoke

techniques are required. 3.5.24. No section should be larger than 300mm x 300mm. Where possible this will be

reviewed at tool design. 3.5.25. At all times repair within the press shall be considered the option of choice so as to

reduce down time to remove broken, chipped punches or sections, if this is deviated then written approval from the tooling coordinator is required.

3.5.26. If the tools are equipped with various punch sizes they must be supplied with a different body diameter to avoid confusion. If not possible mark the punch pads with all sizes to reduce the chance of error of installation.

They are to be held in place with a minimum of 3 SHCS and 2 dowels, all 12.0mm in diameter. Screws are not to be counterbored into the cap. The minimal cross section width of the keeper is to be equal too, the height of the keeper plus 12.0mm. Standard length screws are to be used. The maximum standard screw length is 100mm, keepers requiring screws longer than 100mm must be bolted from two directions. For all strippers that are not using hardened guides but only hardened keeper blocks, the stripper is to guide on both sides of each keeper with a clearance of 0.08mm per side.

3.6.7. Hardened guides are required in strippers only when the stripper is being used for forming, when guided punches are to be used or piloting alignment.

3.6.8. When keepers are not used, purchased components such as Standard Lifter products are preferred methods for retention of travelling components. (i.e., used.)

i. In all application of spools it is the tool vendor’s responsibility to ensure that the possible tensile loads subjected on the cap screws does not exceed that of the screws.

parallel. 3.8.7. Any cavity on the lower die shoe that will collect lubricant must have appropriate drain

holes. 3.8.8. Nitrogen consoles must be mounted on the operators’ side of the die for easy access

and optimum visibility. Consoles must be nested and guarded in an effort to protect from damage by fork lifts,handling and racking.

3.8.9. Nitrogen pressure requirements must be stamped on the die, and the warning labels must be fastened to the die and be clearly visible to the operator.

3.8.10. Dadco cylinders to be used in all die construction. The only deviation will be for fixed solid manifolds where Forward cylinders are to be used.

3.9. Part Branding and Identification Stamps 3.9.1. Identification of F” and “B” are to be included if 2 up common parts are produced for

quality cavity identification purposes. 3.9.2. Whenever possible the number stamp should be able to be mounted on the top of

bottom die shoe. Vendor is to provide clearly labeled part screen dumps of component stamping information with desired position. Screen dump should clearly outline which side of material. Customer approval will be final decision of placement. All Customer Logo’s, engraved stamps and stamp holders are to be provided by supplier of tooling. Stamps cannot be mounted into strippers or pressure pads but must be fixed directly to die shoes striking in information clearly at BDC of die travel. Argon 101 “Foot Style’ letter holders shall be used as the standard for the Van-Rob Julian date. Seven digits of ARG-103 stamps is the standard requirement for the Van-Rob “Julian date (Date run stamp)”. Design of hardened striking pad must be an equal duplicate in height, width and screw pitch of Argon Holder & Backing Plate so as to reverse stamp position to opposite side of material if required. Any diversion from these standards must be reviewed and agreed as part of the Die Design Review process.

3.9.3. All dies are required to have one asset tag (E0019) filled out in full and affixed to the

die by fasteners. These tags are to be mounted on the front inside of the die when space is permitting. Clear, digital pictures must be supplied at buy off in the E0087 Tooling Information Sheet. (Ref., 3.03.16)

4.2.4. Castings with single wear plate construction must have appropriate material for future installation of wear plates.

4.2.5. Removable punch caps GM190 4.2.6. Upper and lower binders for general construction GM246 4.2.7. The Casting thickness on working draw surfaces for draw dies must be no less than 80

mm when finished. Outside walls will have a minimum thickness of 50 mm and all stiffener ribs 40mm with no sharp corners.

Any working surface of the die shoe is to be flame hardened or inserted

for wear


PROCEDURE # E234


Page | 22

4.2.9. For transfer dies, the set blocks are to be a two piece construction with the lower block being no higher than 12mm below the “die lifted” position. Both types of set round block sets are to be held with one screw and 1 anti-rotation pin at the edge.

4.2.10. On lower set blocks only, if the length of the counter bore will be deeper than a standard hex key due to an overly long set block, then a threaded rod stud may be screwed into the bottom of the set block and an anti-rotation pin may be eliminated. If a threaded rod is used, a 13mm hole must be drilled 25mm from the top to aid removal.

4.2.11. The standard pilot required in a transfer die when the pilot is mounted in the die section, is to have the leading area of the pilot ground undersize by 0.18mm per side to ease removal.

4.2.12. Tooling must be designed for continuous operation without stopping to remove scrap. 4.2.13. Master die sets to be completely interfaced with Transfer feed Unit. 4.2.14. Tool vendor to be responsible for engineering interfacing and debugging of transfer

feed with subcontractor. Transfer Tooling will not be sourced to Vendors who have not committed to using reputable subcontractors who are familiar with our transfer systems unless a proven, excellent, past track record of system integration has been satisfactorily proven to Van-Rob.

4.3. Dual Phase Die Construction Criteria

General note: Due to the fact there are no reliable behaviours in the performance of dual phase material we request the following: Competent Simulations are to be used by Vendor to have Van-Rob approve strip layouts & die designs for process. Early supplier involvement in product design to suggest features to hold shape repeatability. Expect several re-cuts in tooling to correct spring back. Perform as much forming preferably net shape in first form/draw (work hardening). All re-strike operations to be in ram direction only. All cutting clearances to be increased to prevent chipping of trim steels. High volume tool trim steels may require Vanadis tool steel (to be discussed at die review)

4.3.1. High-strength materials require dies that are made of premium tool steel that can withstand severe friction. All form sections and trim sections will need to be reviewed for proper application during die review.

4.3.2. Use larger die entry radii than normal. No one radius is appropriate for every drawing application, but a good rule of thumb is six to eight times the material thickness.

4.3.3. Use semi developed blanks whenever possible. 4.3.4. Extra material outside of a finished part increases the amount of stretch that occurs in

a product, and it leaves a large amount of stress-loaded material outside of the drawn part. Trimming away this highly stressed material from the drawn part can cause the part to twist or distort severely.

4.3.5. For dual-phase & High Strength steels, yielding by stretching of material helps to reduce spring back and supplier simulations will be scrutinized at die review to work to best practice known to date in industry. Due to increased usage of this steel in the industry and it’s resulting subsequent production problems, suppliers will be bound to work with Van-Rob to reduce variation of finished parts. This will be done by supplier


PROCEDURE # E234

simulations demonstrating the possible extremes of specified material range. Coupon testing of steels provided will be required by die suppliers to produce best forming geometry in tooling.

4.3.6. Advanced strength steels have higher tensile strength increasing a reverse tonnage condition. All punches will need to accommodate this by shear and staggering heights.

4.3.7. Cutting clearance need to be considered based on the supplied data range.

4.4. Laser Welded Assembly Die Criteria

4.4.1. Pay special attention to tolerancing and GD&T 4.4.2. Tolerancing will be applied to design side of material 4.4.3. GD&T to be consistent for weld tooling checking fixture and clamping methods 4.4.4. All non-mating surfaces should have a design clearance. 4.4.5. Where possible stiffening features are to be added to critical flanges. 4.4.6 Tool maker should be informed of the laser assembled product to show the critical

nature of fit up. 4.4.7. Die plane where possible, is to be consistent with the “A” datum of the part. 4.4.8. All critical holes to be pierced in the same station preferably the last. 4 4.9. Piercing horns and strippers to be cleared to ensure contact to the pierce buttons only. 4.4.10. Calibration stations to be inserted in critical areas. 4.4.11. All die sets are to be healed 4.4.12. All dies are to be spotted and blued to 80% 4.4.13. Bottoming markers are to be used 4.4.14. Burr direction to be away from mating surfaces, when not feasible coining of burr is

4.6. Specialty Die Standards

4.7. Special QDC requirements for VR Waverly and VR Tecumseh 4.7.1. VR Waverley and VR Tecumseh have special requirements for QDC please contact

your tooling engineer for specific information.

5.0 Tool and press specifications 6.0 Standard Tool Maintenance & Sensor Requirements

Die specific to be released with die quote and purchase order. All sensors, purchasing, testing, & correct operational wiring will be the total responsibility of the Vendor.

6.1. Design reviews will always consider the maintenance factors to be successful after launch of new dies. Therefore we expect all designs to show acceptable practices for ease of toolroom maintenance in die review meetings. Van Rob encourages vendors to suggest recommendations for minimum maintenance cost to run dies as part of the die review meeting, this can be included as early as quote stage to explain any cost differentials that may affect a sourcing decision.

6.2. At all times the vendor shall highlight areas that are susceptible to damage during

transportation from storage or maintenance, acceptable warnings are yellow areas on die stating “No Lift”. Whenever possible, these areas will be guarded by physical barriers but not such that they effect part dimensional or scrap ejection.

. 7.0 Die Buy Off Requirements

7.1. Die Try Out 7.1.1. As per tooling check sheets provided by tooling coordinators. Lists will be discussed

with tool shops to ensure tool is ready to ship, tool is ready for try out and when tool is run internally any all issues, if any, during this pre-production run are to be documented. This information will be distributed by the designated Tooling Coordinator within Van-Rob Inc. and the tool shop.

7.1.2. Unless previously agreed Van-Rob Inc. will charge for excessive press time and transportation of dies to and from the manufacturing location. Initial try-out time should be requested through the tool coordinator at least 10 days prior to trial as to input the required time into a production schedule. Press try-out time requirements are to be discussed and reviewed with the plant at die design.

7.1.3. A representative of the source shall be onsite for all try-outs 9 2 representatives for transfer tools). It must be noted that it is not always possible for tryouts to occur during


PROCEDURE # E234


Page | 25

normal work hours; we shall treat this as an exception but require support from tool sources when this does occur.

7.1.4. All parts produced during the try-out are deemed to be rejects and shall be scrapped at source unless, otherwise, requested by a representative of Van-Rob Inc. for their retention. In such situation, these parts shall be identified as per vendor’s tagging procedure and/or Van-Rob Procedure QA015 – Tagging System depending on the location where the tryout is performed.

7.2. Quality Requirements

The following quality requirements are to be considered prior to quoting, this is in addition to any print required tolerance or general tolerance criteria.

General

1. There are 2 fundamental levels of dimension - those with or without critical dimension

symbols.

2. Those that are not marked critical per part but which the technical services department deem critical to another process or step in the parts development.

It is recommended that a detailed study of tolerances be performed prior to kick off.

The vendor is responsible for his own inspection labour for tool approval.

Critical Characteristics Control

1. It is the responsibility of the vendor to supply part(s) that meet the minimum statistical

requirements of critical dimensions, a Cpk of 1.67 is considered the minimum for tooling to be acceptable to Van-Rob Inc. If the study shows that the on-going statistical process control used on the characteristic (either through variable study or functional gauging) indicates that the process is highly susceptible to variations, then it is the responsibility of the tool source to correct this condition at no cost to Van-Rob Inc.

2. Holes may upon prior approval be exempted from this controlled study as we are aware of maintenance issues around punches and bushings and acknowledge that we will see a trend to the higher end of the limit.

3. Tool acceptance will consist of a tool producing acceptable parts in a continuous mode for a

specified period of time; single stroke of dies does not constitute acceptance by Van-Rob Inc. unless single part hand transfer. It is acknowledge at this time that tooling improvements may be required to meet print tolerances.


PROCEDURE # E234


Page | 26

4. All part drawing specifications and tolerances as shown on part prints must be achieved unless otherwise noted on accepted quote. Failure to observe this practice will result in delayed tool approval and payments owing.

5. It is the responsibility of the vendor to supply 6 parts identified numerically 1-6 with a

dimensional report of each cavity /part off location in multiple part dies with print showing dimensions measured and results obtained as a minimum. Van-Rob Inc. will take statistical data on a sufficient run quantity and this information will be available for review by the vendor. It is no longer acceptable on an assembly part for parts fitting gauge to be the only acceptance criteria of Van-Rob Inc. This will be discussed at quote stage and purchase order will state if part is part of an assembly.

6. Failure to achieve the quality /run @ rate/ production sign-off / tool requirements will result in

removal from the approved supplier list with documentation to show cause.

7. All part submissions required are F.O.B. Van-Rob and Due Dates are noted to be on time when at Plant or Integrator on that required date. Vendor is responsible for any delays or damages during shipping so adequate planning, packaging and care is required. Correct Julian date, Cavity Identification, Customer Part Number & Logo if required are to be clear and correct on all parts. All part submissions must come with paper hard copy of CMM or Light Scan reports clearly showing the Julian date and Cavity ID they are reporting on in the shipping box/s. The information on Packaging must clearly outline the Van-Rob code, part quantities, Vendor and Destination source and address as well to Attention: (Name/s of intended receiver/s). Any customs paperwork required for part shipments must be prepared by Vendor.

7.3. Die Specific Requirements

This section will cover annual volume of die, expected run rate in strokes per minute, pieces produced per hit, expected maintenance to meet 1st year production, expected maintenance costs to allow toolroom functions at the plant to set up PM program and expected maintenance hours. This section will be issued with the quote as an addendum to the tool rider.

7.4. Warranty Terms and Conditions

7.4.1. All dies must be warranted for quality and craftsmanship for a minimum of 50,000 strokes or one year during normal full automatic production. In the event a die should crash prior to the end of the warranty period Van-Rob will document by picture and strip/station samples all reasons for the failure. A warranty claim will be submitted to the vendor with all supporting information.

7.4.2. Spare parts will be purchased as required by Van-Rob based on the suppliers Data. The Vendors supplied Data will not be checked for accuracy and if any errors in this information are present, the resulting costs will be carried by the vendor.

7.4.3. It is imperative that the Vendor be present at Home line buy off. If during the run off any failures occur that result in tool damage, it will be at the cost of the Vendor.

7.5. Payment Terms

7.5.1. Payments terms as per purchased agreement. 7.5.2. 100% net 60 from Customers PPAP approval. 7.5.3. Exception sheet to be created and approved by Van-Rob Inc. Personnel.
