Cast molding, also known as (static) casting, is to inject the prepared casting material into a mold to cure it, and obtain a product similar to the mold cavity. The material to be cast may be a monomer, a preliminary polymerized or polycondensed slurry or a solution of a polymer and a monomer. Polymerization or polycondensation reactions usually occur during the curing process. In recent years, some new casting methods have appeared on the basis of traditional casting molding, including inlay casting, centrifugal casting, casting casting, slush molding, rotomolding and the like.
The pressure during casting is low, so the strength of the mold and equipment is not high, and the size limit of the product is small. It is suitable to produce large products; the internal stress of the product is low. Therefore, in recent years, the production output has increased rapidly. Our cast iron table legs use this process.
