Die quenching, especially for automobile molds, requires high hardness, small deformation, and hardened layer depth. Flame quenching has a large amount of deformation, and laser quenching and hardened layer depth is very shallow, which cannot meet the requirements of automobile mold quenching. The use of medium frequency induction hardening to heat treat the outer plate, inner plate and inserts of automobile molds can not only meet the hardness and layer depth requirements of mold quenching, but also greatly reduce the deformation of the mold, which is the best heat treatment process selection.
