Plated Hardware sheet metal stampings

The hardness of nickel coating is relatively high, which can improve the wear resistance of the product surface. In the printing industry, nickel coating is commonly used to improve the hardness of lead surface.

Because nickel metal has high chemical stability, some chemical equipment is also commonly used thicker nickel coating, to prevent corrosion by the medium. Nickel plating layer It is also widely used in functional aspects, such as repairing worn and corroded parts, using brush plating technology for local plating. The electroforming Process for making electrocasts, record molds, and other molds for the printing industry. The thick nickel coating has good wear resistance and can be used as resistance Mill coating. Especially in recent years, the development of composite electroplating, can be deposited with wear-resistant particles of composite nickel coating, its hardness and wear resistance ratio plating

The nickel layer is higher. If graphite or fluorinated graphite is used as a dispersive particle, the nickel-graphite or nickel-fluorinated graphite composite coating is very good Self lubricity, can be used as lubrication coating. Black nickel coating is also widely used as a coating or decorative coating for optical instruments.

The purpose of polishing is to obtain a flat and smooth surface. At this time, the grinding surface also left very fine and uniform wear marks. Polishing is divided into coarse grinding and fine grinding two kinds.

1. Rough grinding is the modification of rough surfaces and irregular shapes.

2. There are still deep marks on the surface of the metal after coarse grinding, which need to be eliminated in fine grinding in preparation for polishing.
