Valve Gate Controllers

Rheo-Pro® sequential valve gate controllers (or sequence controllers) provide accurate control of your injection process by opening and closing multiple gates for optimal fill of hot runner molded plastic parts. Both CV-S and CV-ST series controllers offer a robust graphic user interface for ease of operation and unlimited flexibility and are fully compatible with all MHS valve gate hot runner systems.





Rheo-Pro® CV-ST valve gate sequence controller with integrated temperature control offer a customizable number of control zones and form factors





4 to 300 Control Zones
CV series controllers are ideal for regular molding machines without sequential fill capability. The PLC allows operators to program the controller to their specific molding needs. Each control zone can be programmed for time-based and/or volume-based injection. The nozzles for each control zone can be graphically shown on the touch screen display. The time from start of injection to end of packing (injection plus packing time) is entered into the Close Timer to switch all valves. Individual close times are also available. CV controllers do not require special options from the molding machine other than a simple start signal for the injection cycle. Each controller has an internal memory which stores numerous processing setups and programs with automatic mold identification capabilities.

 




SoftFill™
SoftFill™ offers high quality surfaces for large injection molded plastic parts. This feature reduces injection pressure peaks during the opening of the valve gate (cavity fill phase) by compensating for sudden melt velocity changes. The optional flow control provides variable speed pin actuation designed for sequential valve gating and cascade molding. The system offers a more gentle flow of melt into the cavity to eliminate surface blemishes and hesitation marks. Applications include large surface parts for appliances and automotive.
