Stress Relief Tempering for Die Casting Moulds | Extend Tool Life

Avatar for zhangjieboZhangjiebo
Stress relief tempering is vital for maintaining the accuracy and durability of die casting moulds. Residual stresses caused by EDM machining and repeated heating cycles can lead to cracking, deformation, and reduced tool life. Controlled heat treatment removes these stresses, enhances microstructural stability, and extends mould service performance. ... Read More
