Abstract
The present disclosure provides a method of molding a part. The method may include rotating a screw within a barrel to extrude a molten material through a nozzle orifice into a mold cavity to fill the mold cavity with the molten material, stopping rotation of the screw upon the mold cavity being filled with the molten material, monitoring a parameter indicative of a pressure in the mold cavity, and further rotating the screw to extrude additional molten material into the mold cavity when a drop in pressure in the mold cavity is detected.
