Solutions to Common Problems of Forged Steel Piston

This article focuses on two forged steel piston products of different structures and materials, through the mold stress analysis simulation mold structure optimization, die life is greatly improved, while solving the piston skirt crease, underfill, ejector pin distortion and other technical problems. Piston products for quenched and tempered steels and micro alloy have been adjusted to optimize the heat treatment process, reducing the proportion of scraps in the form of quenching cracks, skirt deformation, and uneven hardness distribution.
