Standard cooling channels are usually not enough to guarantee rapid cycle time repeatability and stress free parts production.
Visual defects are often caused by an overheating around the hot runner tip area.
The long time required to cool the injection point causes a longer cycle time. Conformed cooling channels around the hot runner can solve and avoid many issues of molding process such as sink marks, deformations and cycle time.

We simulate the flow inside the conformal cooling channels and compare the temperatures between traditional cooling and Performal tool inserts.
