How many types of hardware processing techniques are there in Dongguan?

Dongguan hardware processing can also be called metal processing. Modern machining has added electric discharge machining, such as turning, milling, planing, grinding, and boring. In addition, die-casting, forging, and other commonly used processing methods. If it only involves sheet metal, the commonly used methods are milling, grinding, wire cutting (discharge type), and heat treatment.
Dongguan hardware processing can be divided into: automatic lathe processing, CNC processing, CNC lathe processing, and five axis lathe processing. It can be roughly divided into two categories: hardware surface processing and hardware forming processing.

1、 Hardware surface processing can be subdivided into: metal spray painting processing, electroplating, surface polishing processing, metal corrosion processing, and so on.
1. Spray painting processing: Currently, Dongguan hardware processing adopts spray painting processing in the production of large hardware products, which prevents rusting of hardware parts through spray painting processing, such as daily necessities, electrical casings, handicrafts, etc.
2. Electroplating: Electroplating is also the most common processing technique in hardware manufacturing. By using modern technology to electroplate the surface of hardware components, it ensures that the products will not become moldy or rusty after long-term use. Common electroplating processes include screws, stamped 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. By deburring the surface of hardware products, sharp edges and corners are polished into smooth faces, so as not to cause harm to the human body during use.

2、 Hardware forming processing mainly includes: die-casting (die-casting is divided into cold pressing and hot pressing), stamping, sanding, solution casting and other processes.
