The cause and prevention steel deformation after heating treatment process for precision plastic mol

In order to enhance the mold quality and mold life, we need reduce and control the cavity steel deformation after the heating treatment.

• The steel material selected Some type steel property will deform a lots, so we need select proper steel as our require

• The mold structure The deformation sometimes are caused by thin, sharp, groove features

• The internal stress in the metal For some precision molds, we need consider the stress relief before the components manufacture

• The heating treatment technology is inappropriate
