First, Shenzhen precision parts processing:

(1) Classification of precision parts processing:

The precision parts processing industry is very extensive, and can be roughly divided into two categories: metal surface processing and metal forming processing.

Metal forming processing is that we process a piece of iron through mechanical stamping or manual shearing to get the shape we want. For example, the Metal Stamping parts introduced by Shenzhen Chuangxing Hardware Products Factory are metal parts that are stamped and corrected by punching machinery and molds. Metal forming processing is not only these, but also through instrument lathe processing, wire cutting forming processing, etc

(2) Precision metal surface processing:

Hardware surface processing can be divided into: hardware painting processing, electroplating, surface polishing, hardware corrosion processing, etc

1. Painting processing: At present, hardware factories use painting processing when producing large-scale hardware products. By painting, hardware parts can be avoided from rusting, such as daily necessities, electrical shells, handicrafts, etc

2. Electroplating: Electroplating is also one of the most common processing techniques for hardware processing. Through modern technology, the surface of hardware is electroplated to ensure that the product does not undergo mildew and embroidery after long-term use. Common electroplating processes include: screws, stamping parts, batteries, car parts, trinkets, etc.

3. Surface polishing: Surface polishing is generally used for a long time in daily necessities. By performing surface burr treatment on hardware products, for example, we produce a comb. The comb is a hardware piece made by stamping, so the edges of the stamped comb are very sharp. We need to polish the sharp corners into a smooth face, so that it will not cause harm to the human body during use.
