Good Thermal Stability Of Plastic Molds

The shape of plastic injection mold parts is often complex and difficult to process after quenching. Therefore, it is advisable to choose parts with good thermal stability. When the mold is formed and processed by heat treatment, due to the small coefficient of linear expansion, small heat treatment deformation, small size change rate caused by temperature differences, stable metallographic structure and mold size, it can be reduced or no longer processed to ensure the accuracy of mold size and surface roughness requirements.
