We are capable of producing both iron casting and steel casting by using advanced technologies to maximize the quality of outcome products. Coated Resin Sand (CRS), rare high technology in China, is used to process the iron casting such as Anchor cand Block to ensure the precision of dimension and also make the surface of the product feel smooth. De-waxing process is the major way to produce steel casting with great quality. The most common products produced by steel casting is Drill bits and Expansion shell which are the major mining materials. For both iron casting and steel casting, we are able to produce products with wide range of weight from 0.01 kg to 100 kg.
