There is never only a single issue with injcetion molding. Therefore there is never only one solution.
This is always based on real process data measured in the mold. Because good parts are not made with the machine, but only inside the mold. The moment that the melt front passes over a sensor, it is automatically detected by the system. With this information we can determine material viscosity, open and close valve gates, and sequentially control the mold so that flash is prevented.
