ABSTRACT:
An injection molding screw for metal injection molding includes a first end, a second end, a longitudinal body with a first stage and a second stage extending axially along a length of the screw between the ends, a pressure retention device, and optionally, a screw tip. The pressure retention element minimizes loss of pressure in the second stage portion.
