How to deal with deformation of precision casting castings

Casting deformation is a common problem during the casting process, and there are usually several treatment methods:

1. Redesign the mold: If the cause of casting deformation is improper mold design, the mold can be redesigned to reduce or eliminate the possibility of deformation.

2. Adjust the casting process: You can reduce or eliminate the possibility of casting deformation by adjusting the casting process, such as adjusting the casting temperature, cooling rate, etc.

3. Use prestressed technology: Prestressed technology can apply pressure before the casting is formed to reduce the possibility of deformation of the casting.

4. Heat treatment: Heat treatment can change the structure and properties of the casting through heating and cooling, thereby reducing or eliminating the possibility of deformation of the casting.

5. Mechanical processing: If the casting has been deformed, its shape and size can be corrected through mechanical processing to make it meet the requirements.

In short, to deal with the deformation of castings, it is necessary to adopt corresponding treatment methods according to the specific situation, and pay attention to controlling various factors during the casting process to reduce or eliminate the possibility of casting deformation.
