Rust stains are caused by chemical reactions in casting products. Of course, precision casting products are no exception. They inevitably appear rust stains, which will greatly affect the aesthetics of the products. So the precision casting factory finds that rust should be resolved? Please refer to the following two methods:

The metal materials of precision castings refer to materials with metallic characteristics, such as carbon steel, stainless steel, copper-aluminum composite materials, etc., which are essential materials for forging silica sol castings. The quality of metal materials largely determines the quality of silica sol castings. Let us look at the requirements of precision casting of metal materials.
