RHCM or rapid heat cool molding is an advanced injection molding technology utilizing rapid mold temperature changes, starting with heating the mold surface to a point that exceeds the polymer’s glass transition temperature, then cooling the mold immediately after the mold cavity fills up. This technique is used to enhance the surface quality of a plastic part while keeping the cycle time as short as possible.

Advantages

Stress Release:

Reduced or eliminated weld lines and sink marks;

Rainbow effect is eliminated on transparent parts

Appearance & Color Stability:

Superior finish for high gloss and textured surfaces.
