Dec 21, 2015 · 1. Injection phase: In theory, during this phase the cavity is fully filled with molten plastic. But since plastic melt is compressible, in practice no one really knows if the mold is 100% filled with melt or is filled more than 100%. For this reason, the mold is typically filled to about 95-98% in the injection phase. 2.
May 06, 2013 · During the injection molding process molten plastic flows through channels called “runners” into the mold cavity. The direction of flow is controlled by the “gate” at the end of each channel. The system of runners and gates must be carefully designed to assure even distribution of plastic and subsequent cooling.
