Hardware processing accounts for the majority of precision parts processing. I would like to share with you the technological functions of hardware, and I hope to help you.

1、Casting function: refers to some process functions of whether the metal or alloy is suitable for casting, mainly including flow function and full casting ability; Shrinkage, ability of volume shrinkage during casting solidification; Segregation refers to the inhomogeneity of chemical composition.

2、Welding function: refers to the characteristic that two or more metal materials are welded together by heating or heating and pressure welding, and the interface can meet the application intention.

3、Top gas section function: refers to the function that metal materials can be upset without cracking.

4、Cold bending function: refers to the function that metal materials can accept twists and turns without cracking at normal temperature. The degree of twists and turns is generally determined by the angle of twists and turns α The ratio of (external angle) or bending center diameter d to material thickness a shows that the greater a or the smaller d/a, the better the cold bending property of the material.

5、Stamping function: the ability of metal materials to accept stamping deformation processing without cracking. Stamping at normal temperature is called cold stamping. The inspection method is cupping test.

6、Forging function: metal materials can accept plastic deformation without cracking during forging.
