GAMMAFLUX introduces new line of temperature control systems for sequential valve-gate plastic hot runner applications

Gammaflux Inc. of Virginia USA, a leading supplier of Plastics Injection Mould Hot Runner Temperature Control Systems, has introduced a new line of products specifically designed for sequential valve gate hot runner applications.

Moulders of large, complex or difficult to fill parts often use sequential valve hot runner systems to achieve numerous benefits, including knit line control, improved straightness, lighter weight parts, and dimensional improvement. These systems use either pneumatic or hydraulic valve gates that are selectively opened and closed to precisely control gating on the part surface, and the material flow front.

“Sequential valve gating is being increasingly used by moulders to produce the best possible parts, shot after shot.” said Mike Brostedt, Director of Market Development at Gammaflux. “We had provided temperature control systems for SVGC in the past, but through extensive input from our partner processors we have now introduced these new controllers that are specifically for these applications.”

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 8, 16 or 32 valve gates. Stand-alone systems are offered for just sequential valve gate control and all come standard with a 5 year warranty (2 year warranty applies to the touchscreen interface).

Benefits of the Gammaflux SVGC controllers include:-

• Advanced diagnostics for easy trouble shooting

• High speeds (open and close gates every 1 millisecond – 8 output versions)

• Integrated hot runner temperature control and SVGC in one enclosure

• Control of 8, 16 or 32 pneumatic or hydraulic valve gates

• Easy calibration

• Programmable alarms
