Molding core for the manufacture of a piston for a combustion engine determines a hollow chamber arranged between a hub hole for a piston bolt and the piston base and partly the inner shape of the piston

摘要

Molding core (10) determines a hollow chamber arranged between a hub hole for a piston bolt and the piston base and partly the inner shape of the piston. The molding core is removed from the piston after the casting process. An independent claim is also included for a cast piston for a combustion engine.
