Sequential valve hot runners

Gammaflux (Sterling, VA) has introduced a new line of hot runner systems specifically designed for sequential valve gate applications. The new Gammaflux SVGC systems provide numerous benefits including speed, accuracy, and repeatability to help molders gain better control of their hydraulic or pneumatic sequential valve gate hot runner process. Gammaflux offers systems with both hot runner temperature control and sequential valve gate control in one enclosure, with one interface and one menu for both the hot runner and sequence. These integrated systems can open or close eight, 16, or 32 valve gates. Stand-alone systems are also offered for just sequential valve gate control.

“Sequential valve gating is being increasingly used by molders to produce the best possible parts, shot after shot,” says Mike Brostedt, director of market development at Gammaflux. Benefits include advanced diagnostics for easy troubleshooting, high speeds (open and close gates every 1 ms in the eight-output version), easy calibration, and programmable alarms. —stephen.moore@cancom.com
