Abstract
A molding apparatus for injection molding or compression molding includes an “A” portion of a mold, a “B” portion of the mold, and at least one core plunger/ejector. The core plunger/ejector provides dual functionality, wherein it participates in molding operations by consolidating a feed material in the mold cavity, and also is responsible for separating the part from various mold surfaces and ejecting it from the mold.
