ABSTRACT:
In a method of producing a piston through casting, the piston has a piston head, a skirt, a pin boss and a supporting area, the supporting area connecting a periphery of the pin boss with the skirt. A plurality of molds are arranged such that the molds form cavities corresponding to a configuration of the piston. Mold matching surfaces between the molds are arranged such that the molds are contacted by each other at positions different from corners of the supporting area of the piston. A casting is performed by using the molds so that the piston is produced.
