The cooling performance of injection molds directly affects product quality and product efficiency. Poor cooling performance can lead to product defects such as deformation and voids, and can also prolong the production cycle.

Breathable steel is a kind of fine-grained powder stainless steel fired at high temperatures, it is also called porous metal, which can be used in injection molds with air trapping problems.

Injection molds generally work at 150-200 degrees Celsius. In mass production, the injection mold needs to withstand the influence of high temperature as well as high pressure.
