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

      1. Spray painting processing: At present, the hardware factory adopts spray painting processing when producing large hardware products, which can prevent hardware from rusting, 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 pieces is electroplated through modern technology to ensure that the products will not be mildewed or embroidered after a long time of use. The common electroplating processes are: screws, stampings, battery chips, car parts, trinkets, etc.

      3. Surface polishing: surface polishing is generally used in daily necessities for a long time. Through surface burring of hardware products, the sharp edges and corners are polished into smooth faces, so that no harm will be caused to human body during use.
