What are the surface treatments of precision hardware parts?

2022-11-25

The surface treatment of precision hardware parts can be divided into oxidation, surface polishing, electroplating, etc.

Surface treatment of precision hardware processing parts:

1. Natural color of oxidation: oxidized surface. This process is used when customers require that some products have bright surface and are not easy to be oxidized, mildewed or blackened for a long time. After oxidation, the color is the same as the raw material, but it will be brighter and more beautifu
2. Surface polishing: surface polishing is commonly used for general decorative parts. By deburring the surface of precision hardware parts, for example, we produce a precision metal car. Some corners are very sharp, so we need to polish the tip of the corners into a smooth surface, so that the assembler will not be injured during use.
3. Electroplating: the most common processing technology in surface treatment of precision hardware parts. The surface of precision hardware parts is plated with the current process to ensure that the products will not be oxidized, mildewed or embroidered after long-term use. The common products of electroplating processing are: lathe parts, nuts and screws, trinkets, stamping parts, etc.

The surface treatment of precision hardware processing manufacturers can also be divided into: primary color air oxidation, electroplating process and surface polishing

1. Primary color of air oxidation: the process of air oxidation surface is used when some customers specify that the surface is bright, the use time is long, and the products are not easy to grow mildew and black due to air oxidation. After air oxidation, the color is the same as the raw material, but it will be brighter and more beautiful.
2. Electroplating technology: Z is a processing technology widely used in surface treatment of precision hardware parts. According to the current production process, the surface of precision hardware parts will be electroplated to ensure that the equipment will not be subject to air oxidation, mildew and rust under long-term use. The common equipment for electroplating process includes: CNC lathe parts, nuts and screws, decorations, metal stamping parts, etc.
3. Surface grinding and polishing: surface grinding and polishing are very common in decorative design works. It is necessary to solve the problem by deburring the surface of precision hardware. For example, when you are manufacturing a precision metal stamping part, some edges are very sharp, so you need to polish the sharp parts of the edges into smooth surfaces according to the surface polishing method, so that it is not easy to hurt the assembly workers in the application process
