Stainless steel precision casting dimensional accuracy and high temperature roasting

Stainless steel precision casting is also called investment casting in the process of production. This is a non-cutting or less-cutting casting process. Stainless steel precision casting is an effective process technology in the industry. Very wide, more suitable for all types of alloy casting.

The casting size and surface quality of Stainless steel castings are higher than other casting methods, and it is more complicated than other casting methods. The castings that are resistant to high temperatures during processing and are not easy to process can be directly used. Investment casting is precision cast.

Stainless steel precision casting is simply effective in the production process by using its fusible materials such as plastic or wax, effectively making a fusible model, effectively coating several layers of special refractory coatings on it. It is then cured after it has been hardened or dried to form a unitary shell.

Effectively use the hot water to melt the model from the shell, effectively place the shell in the sand box, fill the surrounding sand with its shape, and finally put the casting into the roaster and calcine it at high temperature.

Stainless steel precision casting requires high dimensional accuracy. Under normal circumstances, it can effectively reach CT4-6. Due to the complicated process of investment casting, there are many factors affecting the dimensional accuracy of castings, such as the deformation of the investment mold and the shell. In heating, shrinkage of the molding material, and the like.
