Six processes for processing metal stamping parts

Six processes for processing metal stamping parts

1. Casting performance: refers to the process performance of metal or alloy whether it is suitable for casting, including flow performance, ability to fill the mold; shrinkage, the ability to shrink the volume when the casting solidifies; segregation refers to the unevenness of chemical composition.

2. Top gas section performance: refers to the performance that metal materials can bear upsetting without breaking.

3. Welding performance: refers to the characteristics of welding two or more metal materials together by heating or heating and pressure welding methods, and the interface can meet the purpose of use.

4. Stamping performance: the ability of metal materials to withstand stamping deformation without breaking. Stamping at room temperature is called cold stamping. The inspection method is tested by cupping test.

5. Cold bending performance: refers to the performance of metal materials that can withstand bending without breaking at room temperature. The degree of bending is generally expressed by the ratio of bending angle α (external angle) or bending center diameter d to material thickness a. The larger a or the smaller d/a, the better the cold bendability of the material.

6. Forging performance: The ability of metal materials to withstand plastic deformation without breaking during forging.
