ABSTRACT:
A mold for forming a magnetic tape cassette and a method for multi-color molding a magnetic tape cassette or the like. Sprue-runners connected to submarine gates used in making at least portions of the cassette are formed with notches near the submarine gates to reduce the cross-sectional area of the sprue-runners. As result, the sprue-runners can be easily cut off from the body of the cassette by breaking the notched portions.
