ABSTRACT:
A method of producing a casting by using a plastic core. The plastic core is made of a thermoplastic resin and set in a casting mold so as to form a cavity in the casting mold. A molten metal such as aluminum is poured under pressure into the cavity to form the casting (product). The plastic core maintains its initial shape during casting. The remaining heat of the casting or the solidifying metal causes the plastic core to melt after the casting so that the molten plastic core is easily removed.
