Abstract
The invention contemplates a sprue-gate configuration embodied in one of the cavity-defining parts of a multiple-part mold for injection molding of plastic articles. At the gate region of sprue discharge into the cavity, the sprue converges into communication with a cluster of restricted-gate orifices which are in closely spaced, angularly distributed relation about the generally central axis of the sprue. The combined area of the restricted-gate orifices may be less than the area of a conventional single-orifice gate serving a cavity of the same size.
