The hardware processing process is to open the material according to the production needs. After the opening, some small parts, such as small parts, can be punched and then processed by gong cutting or CNC processing. This is a lot in the production of glasses parts and auto parts. To make a container: it is to go to welding after cutting and punching, and then spray oil after sanding, and then assemble the accessories before shipment. For small hardware accessories, there is a lot of surface treatment after grinding, electroplating or oil injection. Then welding or screwing to assemble and package for shipment. So, what are the classifications of surface processing of precision hardware parts?

1. Spray paint processing: The hardware factory adopts spray paint processing when producing large-scale hardware products, and the hardware parts are prevented from rusting through spray paint processing, such as: daily necessities, electrical enclosures, handicrafts, etc.

2. Electroplating: Electroplating is also the most common processing technology for hardware processing. The surface of hardware parts is electroplated through modern technology to ensure that the products will not become mildewed and embroidered under long-term use. Common electroplating processing includes: screws, stamping parts, Batteries, car parts, small accessories, etc.

3. Surface polishing: Surface polishing is generally used in daily necessities for a long time, by surface polishing hardware products.

4. Burr treatment For example: we produce a comb, the comb is made of hardware by stamping, then the corners of the punched comb are very sharp, we need to polish the sharp parts of the corners into a smooth face, so that In the process of use, it will not cause harm to the human body.
