TRANSCRIPT
• Discuss good manufacturing practices in container glass for hot end reporting of glass defects v/s cold end reporting of glass defects
• Discuss heldware process• Discuss on Concepts • Benchmark and customize them to our process
Agenda
• Hot End Area – IS Machine From Gob cuts to Lehr exit Operator
Upkeep
• Cold End Area – From Cold End entry to Case packerCold end checker
Areas & Members
•Hot End Area-Lehr Entry Standard –e.g. 97% , Cold End Entry - 96%-Automatic defect identification equipment Standard
Sqzer(0.5%),OLT(1%),DPG(1%), CHD(1%),MCAL(1%),MNR(1%)- % Pack Operating Standard – e.g. 90%
- Hot end operator to do Set out every 1 hr.
- Critical , Major , Minor and check with AQL- Kicked out in the Hot end Reject (Hot End Reported Defect)- Communicated to the Cold End Checker & Upkeep- Upkeep will solve the defect, communicate to Cold end
checker and fill critical defect report
Hot End Area
No defect FoundDefect Found
•Cold End Area-Defect Communicated by Hot End operator-Check Last set out on sheet, computer-Check Lehr for ‘x’ no. Of bottles
- Critical , Major , Minor and check AQL- Kicked out in the MNR- Go for Audit @ the case packer; Audit ‘x’ no of cases/bulk
Cold End Area
No defect Foundafter ‘n’ times checkCommunicated to HE

•Cold End Area-Will not take cavity out from MNR till ‘x’ no of bottles are checked and defect closed is confirmed-Qualify any equipment change-Run samples on Automatic detection equipment
•Hot End Area -Communicate to cold end on what was done to fix defect - Ask for qualification of any equipment change
Cold End Area
• Bottle counters–Gob Cuts,Lehr Entry, Cold End Entry, % Pack• Automatic Defect Identification and Rejection Machines• Mold No. Reader and Rejection• XPAR• SIL system & its Advantages• HER v/s CER• Critical Defect Report• Held ware concept• MIS for defects• Job On Job Off concept
•Bottle Code Identification•Automatic Weight Control & Recording of Weight•SOPs & TOPs – e.g. On New M reject for 20 cycles/Cold Mold

• XPAR- Using infrared variations to detect defects in glass containers
in the hot end before entering the LEHR- Thickness, Swab wear, Black spots, Stones, Bird swings
• SIL system & its Advantages- SILMOLD,SILQUAL,SILPROD,SILWARE all incorporated-Communication platform between HE & CE-Bottle counters history
- Automatic detection machine history- Machine/Section downtime history- Equipment history/hrs- Defects history

• HER v/s CER• Critical Defect Report• Held ware concept & Recording
