Metal processing can be divided into: automatic lathe processing, CNC machining, CNC lathe processing, five-axis lathe processing, can be roughly divided into: metal surface processing, metal forming two categories.
First, the subdivision of metal surface processing can be divided into: metal painting processing, electroplating, surface polishing processing, metal corrosion processing and so on.
1. Paint processing: At present, the hardware factory adopts paint processing when producing large-scale hardware products. Through painting, the hardware can avoid rust, such as daily products, electrical enclosures, and handicrafts.
2. Electroplating: Electroplating is also the most common processing technology for hardware processing. Electroplating is performed on the surface of hardware by modern technology to ensure that the product does not undergo moldy growth for long periods of time. Plating processes are common: screws, stampings, Cell, car parts, trinkets, and more.
3, surface polishing: Surface polishing process is generally used in daily necessities, through the surface treatment of hardware products, burrs, sharp edges will be thrown into a smooth face, so that in the course of use will not cause harm to the human body.
Second, the metal forming process includes: die-casting (die-casting and sub-cold pressure and hot pressure), stamping, sanding, mold casting and other processes
