The English expression of hardware parts is MetalParts or HardwareParts. Traditional hardware parts are generally small hardware, and the materials are generally made of iron, copper, aluminum, steel and other materials through forging, die-casting, cutting and other physical processing. Devices, in fact, hardware parts also include mold hardware, mechanical hardware, home appliance hardware, household hardware, communication hardware, window hardware, construction hardware, etc. In addition to the use of mechanical processing technology, hardware processing is generally accompanied by Surface treatment technology, let it enhance some specific performance, today follow Hongweisheng to take a look, what are the common surface processing technology of hardware parts:

1. Spraying processing. When the hardware factory produces large-scale hardware parts, they generally need to spray the surface on them. Common spraying processing includes powder spraying, oil spraying, paint spraying, etc., and the sprayed ones we use daily Hardware parts include the shells of electrical appliances and mechanical equipment, etc.;

2. Electroplating. Electroplating is a process often used in the processing of hardware parts. The surface of the hardware parts is electroplated through modern technology to ensure that the parts will not be mildewed and grown during long-term use. Rust, common parts that need to be electroplated include screws, metal accessories, stamping sheets, car parts, etc.;

3. Polishing, surface polishing is more common in our common daily parts. Polishing the surface of hardware parts can achieve the effect of removing burrs. For example, we often use stirring, stainless steel bowls and watch straps in our kitchenware. , Equipment metal probes, etc., after mechanical processing, some burrs often remain. These burrs will cause trouble in later use, such as scratches, cuts, scratches, etc., so after polishing, The subsequent use process is more convenient and avoids harm to the user.

The above are three common surface treatment processes for hardware precision parts processing.
