Six-point process performance of precision hardware parts processing

In the processing of fine parts, hardware processing accounts for the vast majority. Let me share with you the technical performance of the hardware, hoping to help everyone.

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

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

The performance of the top gas section: refers to the performance of metal materials that can be forged without breaking.

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 the bending angle α (external angle) or the diameter of the bending center d to the thickness a of the material. The larger a or the smaller d/a, the better the cold bending property of the material.

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

Forging performance: The performance of metal materials that can accept plastic deformation without breaking during forging and pressing.
