SVG+ Simple, yet smarter.The New Standard for Sequential Valve Gate Molding
Stabilize your Process
H O T R U N N E R T E C H N O L O G Y
As the leading innovator in sequential valve gate molding, we continually strive to perfect our hot runner solutions, providing the most efficient way to achieve superior molded parts.
Our high degree of customer service, matched with the most technological advances, means your success in injection molding. The SVG+, the new standard for hydraulic and pneumatic Sequential Valve Gating applications, offers numerous patented design enhancements for superior performance and efficiency. Improve your molding process with SVG+:
Simple designs: No cooling lines or plates required.
Easy set up and troubleshooting: Features that provide significant time savings by providing improved monitoring and diagnostics tools from outside of the machine. This results in less downtime, less scrap and increased reliability.
Allows for easy upgrade to activeGate® technology for increased molding control and improved part surface quality. High quality Class A part surface finishes, and the ability to mold parts with complex geometries and high dimensional stability are easier to achieve in less time.
Reduce the cost of your molding operation: Faster start up Faster tool changes Higher production utilization rates Better part quality Higher productivity

Valve Pin Monitoring Synventive’s patented pin monitoring (VMI) via sensor technology facilitates easy set up for your sequential valve gated applications and provides full monitoring, diagnostics and trouble shooting from outside the machine. Having VMI installed allows you to check that your valve pins are moving as intended, from outside the mold tool. This removes the need for unsafe physical pin checks, and also provides measured individual pin movement data.
Real time valve gate status Trouble shooting (of open/close issues)
from outside of the machine Check that the piston is traveling
as intended Read actuator opening times,
during the molding process.
What VMI can do: Valve pin diagnostic tool for quickly
troubleshooting your hot runner system Eases process setup of symmetrical zones Simplifies mechanical flow restrictor
application set up Display valve pin movement status VMI will display the valve pins last shot
opening time in seconds Ensures correct plumbing and
labeling of zones Signal outputs for data logging
Easy Set Up
Calibration stored in junction box; single main module can be used on multiple systems
Open, intermediate, and closed position status lights for real-time indication of pin position
Connection provides signals to other equipment such as data-logger to capture pin opening measurement data for quality control purpose
LCD displays opening times for 2 selectable zones
Position sensor sends signals to the junction box
Why Choose Synventive: Expert application knowledge Application simulation Experienced team of engineers Robust product line Best in class features Exclusive flow control technologies Local support at startup Leading service for the life of the tool

Self-Cooling Actuator The Synventive self cooling actuator eliminates the need for water lines. No cooling plates, lines or water required so there are no clogs, contamination issues to worry about.The new patent pending SynCool3 design provides actuator cooling via proprietary thermal conductors making contact with top clamp plate.SynCool3 provides these important benefits:
Preheat without damage to actuator or seals No more clogged cooling lines Prolonged actuator seal life with less service By removing cooling plate, manifold
temperature uniformity is improved Facilitates quick mold changes by
eliminating need to cool down hot runner Prevents overheating and degrading of
hydraulic fluid
The new patent pending modular actuator has a thermally isolating design, which prevents overheating and includes a number of other additional features:
Uniform bolt-on modular actuator series Hydraulic & Pneumatic hot runner systems Supplied as Plug ‘n Play® system for easy
installation & startup Pre-plumbed / Pre-wired / Pre-tested A patent pending automatic bleed Easy access to pin for adjustment and
quick pin decouple

Upgradable to activeGate® All SVG+ Systems are supplied as activeGate enabled. Simply connect a VMI for pin position monitoring, or if greater control is required, upgrade to the appropriate activeGate control technology.activeGate technology provides greater control for the molding process and improves part surface finish. By controlling the flow of plastic out of each gate, activeGate control technologies have minimized or eliminated a variety of part surface defects. activeGate provides precise control of the position, acceleration, velocity and stroke of each valve pin. Benefits include:
Higher quality part surface finishes Ability to mold parts with complex
geometries and high dimensional stability Higher production rates Clamping force reduction Ideal for family or modular molds Decreased scrap
activeGate is a scalable technology. All systems are supplied activeGate enabled, allowing for easy upgrade to the appropriate technology when required.
