Surface processing of hardware parts

文章來源:Wen'an County Angru Metal Products Co., Ltd    更新時(shí)間:2023-05-06 16:43:37

  The hardware processing process is to cut materials according to production needs. After cutting, some small parts, such as production, can be processed by punching machines or CNC machining, which is widely used in the production of glasses and automotive parts. And making containers: it means performing a cutting punch, then welding, sanding, and then spraying oil, and then assembling accessories to ship. For hardware accessories, there is still a lot of surface treatment, electroplating or oil spraying after polishing. Then, it is welded or screwed, assembled, packaged, and shipped.
  1. Spray painting processing: Hardware factories use spray painting processing when producing large hardware products, to prevent rusting of hardware components, such as daily necessities, electrical enclosures, handicrafts, etc
  2. Electroplating: Electroplating is also the most common processing process in hardware processing. Modern process technology is used to electroplate the surface of hardware components to ensure that products do not undergo mold or embroidery after long-term use. Common electroplating processes include screws, stamping parts, battery cells, car parts, small accessories, etc,
  3. Surface polishing processing: Surface polishing processing is generally used for a long time in daily necessities. For example, if we produce a comb, which is a hardware component made by stamping, the edges and corners of the comb are very sharp. We need to polish the sharp parts of the edges and corners to create a smooth face, so as not to cause harm to the human body during use.
