Investment castings are easy to be deformed during production process.We can divide the deformation into self micro-deformation,flaring deformation and warping deformation.

Common pouring ways of investment castings

Impeller investment casting parts are typical investment castings.Common material of such parts are stainless steel.There are high quality requirements for casting quality,machining,dimension accuracy and surface roughness.Below are some aspects that the effect of impeller investment castings struct......

Carburizing and quenching  is a common heat treatment process,After carburizing,the surface of investment castings could obtain high hardness,Thusimprove its wear-resisting degree.Traditional process mainly include:the low temperature tempering,direct quenching after cooling,first heating quenching,......

Surface hardening process refers to make surface hardening of investment castings,but the core still have strong toughness.Through this process,we can improve the wear resistance and fatigue resistance of investment castings.As the core still has good toughness and strength,so investment castings af......

Thread is widely required for machining investment castings. According to the assembling purpose, customer marked drawings of castings with thread standards. We need to machine the threads when investment castings finished. Currently, we machine the threads mainly by two processes. One is lathe thre......
