What are the main process characteristics of metal precision parts processing? These six processing processes include casting, top gas section, welding, stamping, cold bending and forging. Let’s take a look at the relevant contents:

Hardware precision parts processing
1. Casting property: it refers to whether the metal or alloy is suitable for casting some process properties, mainly including flow property and mold filling capacity; Shrinkability, the ability of volume shrinkage during solidification of castings; Segregation refers to the inhomogeneity of chemical composition.

2. Top gas section performance: refers to the performance of metal materials that can withstand upset forging without fracture.

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

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

5. Cold bending property: refers to the property that metal materials can withstand bending without cracking under normal temperature. The bending degree is generally the bending angle α The ratio of (external angle) or bending center diameter d to material thickness a indicates that the larger a or the smaller d/a, the better the cold bending property of the material.

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