SVG+ Hot runner systems
SVG+, the New Standard for Sequential Valve Gate Molding
SVG+ systems boast the latest patented hot runner advancements, providing the optimum and most reliable molding solution for large part applications
Synventive - the leader in sequential valve gate applications, is pleased to announce the SVG+ hot runner systems. The SVG+ features numerous patented design enhancements offering superior performance, efficiency and reliability for sequential molding of large parts:
Simple designs: No cooling lines or plates required – delivering increased reliability in the molding process.
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 lower operating costs and improved 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.
The SVG+ actuated systems are equipped with new modular actuators and the patent pending SynCool3 technology. SynCool3 provides indirect cooling of the actuators without the need for separate cooling lines.
SynCool3 provides these important benefits:
Preheat without damage to actuator or seals
No more clogged or leaking 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
For easy set up of sequential valve gated applications these systems are delivered with a Valve Monitoring Interface (VMI) for monitoring, diagnostics and troubleshooting from outside the molding machine. VMI provides measured individual pin movement data and opening times and allows operators to check that the valve pins are moving as intended. VMI offers:
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
For even more control, the SVG+ actuators are equipped with sensors that facilitate an easy upgrade to an activeGate control technology. activeGate is a scalable technology that provides greater control for the molding process and improves part quality. By controlling the flow of plastic out of each gate, activeGate control technologies have minimized or eliminated a variety of part surface defects. The technology provides precise control of each valve pin, which includes position, acceleration, velocity and stroke.
