The Sequential
G24 SVGC
Manufacturers of large, complex or difficult to fill parts often turn to Sequential Valve Gate Control (SVGC) to solve molding issues. All SVGC applications have hot runner manifold or melt delivery systems feeding individual nozzles. Using SVGC the processor has the ability to selectively open or close each valve gate nozzle individually to precisely control the material flow. The most common pin actuation methods are pneumatic or hydraulic. Filling the part in a sequence or selectively shutting off individual cavities could have the following benefits:
- Knit line control
- Improved cosmetics
- Stronger parts
- Less warpage
- Lighter weight parts
- Dimension improvement
- Cavity fill balancing
- Family mold balancing
- Reduced injection pressure
- Reduced machine tonnage
Temperature SVGC can be combined in one enclosure and with one user interface. Up to 48 nozzles can be sequentially controlled.
