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 latest technological advances, means your success in injection molding. SVG+, the standard for hydraulic Sequential Valve Gating applications, offers numerous patented design enhancements for superior performance and efficiency. Improve your molding process with SVG+:

Easy set up and troubleshooting: Features that provide significant time savings by providing 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.

Simple designs: No cooling lines or plates required.

Reduce the cost of your molding operation: Faster start up Faster tool changes Better part quality Higher productivity Upgrade only if needed

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

opening time in seconds Ensures correct plumbing and

labeling of zones Signal outputs for data logging

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

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

Valve pin opening times are displayed

Position sensor sends signals to the junction box

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 troubleshooting from outside the machine. Having VMI installed allows you to check that your valve pins are moving as intended, from outside the machine. This removes the need for unsafe physical pin checks, and also provides measured individual pin movement data.

Self-Cooling Actuator SVG+ systems may include a self cooling actuator which can eliminate the need for water lines in most applications. No cooling plates, lines or water required so there are no clogs or contamination issues to worry about.This patented 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 Patented automatic bleed function Easy access to pin for adjustment and

quick pin decouple Improved manifold temperature uniformity

over water cooled system Facilitates quick mold changes by

eliminating need to cool down hot runner Prevents overheating and degrading of

hydraulic fluid

Supplied as Plug ‘n Play® system, ready for easy installation & startup.

Upgradable to activeGate® 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 technology.activeGate technology provides greater control for the molding process and can improve part quality. By controlling the flow of plastic out of each gate, activeGate can minimize or eliminate a variety of part cosmetic defects. Benefits may include:

Higher quality part cosmetics Ability to mold complex geometries

with high dimensional stability Higher production rates Clamp force reduction Balancing of family or modular molds Decreased scrap
