STEEL OR ALUMINIUM PISTON FOR A COMBUSTION ENGINE, AS WELL AS METHOD FOR PRODUCING AT LEAST ONE PART OF A STEEL OR ALUMINIUM PISTON FOR A COMBUSTION ENGINE

摘要

The invention relates to a steel or aluminium piston for a combustion engine, comprising at least one cooling channel (14) in which pins (16, 22) extend both substantially in the piston shaft direction, and in a substantially radial direction, and/or which has undulations, widening parts and/or tapering parts. In a method for producing at least one part of a steel or aluminium piston of this type for a combustion engine, an additive production method is used.
