ABSTRACT:
An injection molding machine that includes a base assembly having separable mold halves in which at least one removable liner is contained between the opposed surfaces of the mold halves. The liner has a molding cavity formed therein. When the assembly is closed, the liner is clamped between the mold halves and molten material is delivered into the cavity through the existing sprue system to fill the cavity. Opening the mold permits the liner to be removed and the part is separated therefrom from the liner.
