Shell molding process

Shell molding process use a kind of special sand covered by resin. Under certain degree, it will become hard mold in the die, and will be poured after mold assembling. This process is especially suitable for smaller size castings with high dimensional accuracy requirement. By this process we can also reduce the labor work for molding, getting better production efficiency.
There have no limitation on casting materials, we can cast iron, carbon steel, alloy steel, aluminum and copper material products. These castings usually have small or medium weight, with high requirement on accuracy and surface quality, such as pump shell, some cover castings or link castings.
