An injection screw and barrel for small injection molding shots employs separate plunger and flight sections so that the plunger section may be arbitrarily reduced in diameter without adversely affecting the threaded portion of the flight section. Melt passes from the flight section to a metering area through a hollow bore in the plunger section.
