At Foshan Zeren Precision Casting Co., Ltd., we specialize in investment casting, also known as lost-wax casting, which involves several key processes: wax injection, repair, tree assembly, slurry dipping, dewaxing, metal pouring, and post-processing. First, a wax pattern is created, coated with slurry to form a mold, and hardened. The mold is then heated to melt out the wax, leaving a ceramic shell. After firing, molten metal is poured into the mold to create the final part once it cools.

Of course, the application of investment casting alloys is very extensive, and there are many types of materials. Below are the common materials categories:

Material Type	Material Grade
Carbon Steel	Q235, Q355, 1035, WCB, 1.0619, S20C, S45C……
200 Series Stainless Steel	201, 202, S20200, 284S16……
300 Series Stainless Steel	304, 304L, 321, 316, 316L, 309S, SCS13, SCS16, CF-8M, 1.4401, 1.4408……
400 Series Stainless Steel	410, 410S, 420J1, 420J2, 430……
