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:

Precision casting products are basically metal materials, so the surface of their castings is easy to rust. If the surface of the equipment is rusty and it is difficult to clean up later, it will directly affect the use of precision castings. In the processing of precision castings, clean water should be used to clean and soak the workpiece, and the workpiece should be cleaned before chemical degreasing and rust removal. This can clean the workpiece, the precision casting process and the use of cold iron

Regarding the development of precision casting companies, we must first know what precision casting is. Casting is a method of manufacturing parts. The prototype of precision casting has a long history in my country, among which landmark buildings such as the famous bronze lion won the bid. In ancient times, we also used this technique to make various utensils. Later, with the development of the times, this technology gradually spread to developed countries such as the United States. They combined principles and high technology to form the current foundry enterprise.

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.
