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 after case hardening have good resistance to impact load.Surface hardening treatment methods mainly include carburizing&quenching, nitriding, hard anodic oxidation, chrome plated, and metallic cementation, etc.
Injecting the refractory mix bled into the core cavity after solidification the green core is removed from the cavity.
Refractory mix of the known quantity is mixed with the liquid binder, for each single core to be produced.
Each enterprise all expects to enlarge the sales of stainless steel investment castings by improving casting quality.But it is not easy for stainless steel casting company to do this job.According to our many years' experience,we could improve the quality and reduce costs from these aspects:
Ceramic cores are used to produce Intricate Internal Shapes in production of Investment Castings.With the help of Ceramic Cores,critical castings applied in Power Generation,Automobile,Transmission and other industries can be done in Investment Casting.
Investment casting process is suitable for almost all the ferrous and nonferrous materials.As a top investment casting foundry,Tongda foundry could make both ferrous and non ferrous investment castings for our customers.Now we would like to introduce what alloys can be poured in investment casting process:
