The subdivision of hardware surface processing can be divided into metal oxidation processing, metal painting processing, electroplating, surface polishing processing, metal corrosion processing and so on. As a CNC machining service factory, let's talk about it in detail.
1. Oxidation treatment: When the hardware factory produces hardware products (mainly aluminum parts), oxidation treatment is used to harden the surface of the hardware products and not easy to wear.
2. Spray painting process: The hardware factory adopts the spray painting process when producing large hardware products, and the hardware parts are sprayed to avoid rust, such as daily necessities, electrical appliances shells, handicrafts, etc.
3. Electroplating: Electroplating is also the most commonly used processing technology for metal processing. The surface of the hardware is electroplated with modern technology to ensure that the product will not be moldy or embroidered for long-term use. Common electroplating processes include screws, stamping parts, battery slices, auto parts, small accessories and so on.
4. Surface polishing: Surface polishing is generally used for daily necessities, through the surface burr treatment of hardware products. For example, we produce combs. The combs are made of stamping hardware, so the corners of the punching combs are very sharp. We need to polish the sharp parts of the corners into a smooth surface, so in the process of use, it will not Cause harm to human body.
