Considered the third phase of the Injection Molding Cycle, the Cooling Phase consumes the greatest amount of time. Therefore, it is a serious area for designers and mold makers to make sure that all Coolant schemes have been thoroughly investigated for their suitability.

Slide Action requires several mechanical components to enable the molding of complex part geometry.   Slides are usually used for exterior action, and typically pull a core located on the "B" side of the mold.
