Introduction of casting process
Our casting process is the iron based precoated sand casting and shell mold sand casting, with this method, a smooth casting surface can be achived For the iron based precoated sand casting, The inner quality is better because of the shock chill of the iron mold.
There are other types of casting method in different foundries, such as low wax casting, precision silican casting, lost foam casting, vaccum casting, resin sand casting, green sand casting, clay sand casting.centrifugal casting. powder casting, die casting. Different method require different moulding sand, and casting surface and inner quality is different according to different moulding sand.
According the material, there are grey iron sand casting, ductile iron sand casting, stainless steel casting, carbon steel casting, high Mn steel casting, bronze casting, aluminum casting.
Different size ,weight, quantity and material of the castings should use differrent casting method. Small size and weight stainless steel casting should use the precision silican casting or lost wax casting to get good dimension and outlooking. Big part and small quantity can choose green sand casting and clay sand casting, the cost will be lower. For batch quantity and small size aluminum can use die casting, fast, good looking and good quality.
