Cold extrusion die is a common heat treatment method. Plastic molds treated in this way must have high strength and excellent wear resistance, because during cold extrusion, the metal will be subjected to uneven pressure in three directions, and a certain degree of deformation will occur. A mold with good performance can withstand repeated strong pressure without being damaged, and at the same time, it must have the ability to resist small plastic deformation, so as to ensure that the mold remains stable under strong cold extrusion.

Plastic mold

When the mold steel is deformed, a thermal effect is generated, and the temperature of the mold accessories and the entire mold will increase. The mold material cannot withstand high temperatures and causes deformation or even failure. Therefore, it is necessary to ensure that the mold has high tempering stability.

In order to meet the performance requirements of cold extrusion molds, pay attention to avoid material carbide segregation during heat treatment, use normal process offline temperature for quenching, control a certain amount of residual austenite, and use isothermal quenching as much as possible to avoid the situation where the strength of each part of the material is different. Perform low-temperature stress relief tempering during use, and do a good job of surface strengthening.
