Basic classification of hardware processing industry

Hardware processing industry is very extensive, according to the roughly can be divided into: hardware surface processing, hardware molding processing two categories.

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

and so on.
1. Painting processing: At present, hardware factories use spray painting processing when producing large hardware finished products, and avoid rust of hardware through painting processing, such as: daily necessities, electrical shells, handicrafts, etc.
2, electroplating: electroplating is also the most common processing technology of hardware processing, through modern technology on the surface of hardware plating, to ensure that the product does not occur mildew embroidery under long-term use, electroplating processing is common: screws, stamping parts, battery sheets, car parts, trinkets and so on.
3, surface polishing processing: surface polishing processing is generally used for a long time in daily necessities, through the surface burr treatment of hardware products, for example: we produce a comb, the comb is made of hardware by stamping, then the corners of the stamped comb are very sharp, we have to throw the sharp part of the corners into a smooth face through polishing, so that it will not cause harm to the human body in the process of use.

Second, hardware molding processing Hardware forming processing is that we will a piece of iron through mechanical stamping or manual cutting processing to the shape we want, such as hardware stamping parts is through punching machinery and mold stamping and positive hardware accessories, hardware forming processing is not only these, but also through instrument lathe processing, wire cutting molding processing

, CNC lathe one-time forming processing, etc. For example, Dongguan Donghuang Precision Components Company adopts CNC CNC walking machine, computer gong and other advanced hardware processing automatic assembly line, precision cutting processing of materials, one clamping (automatic feeding) can process internal and external cone, male and imperial threads, spherical surface, drilling, tapping and other complex processes.
