Surface processing method of precision stamping parts
The application of precision stamping parts in our lives is very widespread, often involving the functional requirements of the appearance of wear resistance and corrosion resistance. In order to further improve the utilization rate of precision stamping parts, it is very important to deal with the appearance of precision stamping parts. The surface processing methods of precision stamping parts are as follows:
1. Painting processing:
Precision stamping parts processing plants use spray paint when producing large hardware products, such as daily necessities, electrical enclosures, and handicrafts. The existence of spray paint not only makes the product not easy to rust, some special spray paint can also produce some other effects, making the product function better.
2. Electroplating, chemical plating:
Electroplating is also one of the most widespread processing techniques for metal processing. Modern technology is used to electroplate the appearance of precision stamping parts to ensure that the products will not be moldy or embroidered under long-term use. Common electroplating processes include screws, stamping parts, battery sheets, Car parts, small accessories, etc. Electroless plating refers to the film-forming technology of depositing a metal coating on the surface of a metal by autocatalytic chemical reaction in a solution in which a metal salt and a reducing agent exist together. Among them, electroless Ni-P alloy plating is widely used. The surface treatment of precision stamping parts is compared with the electroplating process. Electroless plating is a relatively low-pollution process, and the Ni-P alloy obtained is a good chromium-replacement coating. However, there are many process equipments for electroless plating, material consumption is large, operation time is long, working procedures are cumbersome, and the quality of plating parts is not good.
3. Surface polishing processing:
Surface polishing is generally used in daily necessities for a long time. Through the surface burr treatment of hardware products, the sharp corners are polished into a smooth face, so that it will not cause damage to the human body during use.
4. Alloy catalyst fluid skills:
The alloy catalyst liquid is suitable for various metal raw materials, and it can be catalyzed only in the place where it can flow and soak. The product can be processed by heating to about 83°C at room temperature. In the process of processing, the general metal soaking time is about 15-20 minutes. After soaking, wash it with clean water and dry it naturally before use. Sealed and stored under normal temperature and pressure for up to 3-5 years without deterioration. The application range of alloy catalyst liquid is very wide, and it is used in the aviation industry, automobile industry, petrochemical industry, textile industry, hardware industry, mechanical equipment, electronics and electrical engineering, food, medicine and other fields.
5. Oxidation treatment:
The oxidation treatment is mainly anodic oxidation, chemical oxidation, and micro-arc oxidation. In the wear test and the corrosion resistance test, the appearance, oxide layer thickness, friction resistance and corrosion resistance of the aluminum alloy after three kinds of surface treatments were analyzed and compared in detail. The surface treatment results of precision stamping parts show that different thicknesses of oxide films can be formed on the surface of aluminum alloy by different surface treatments, the surface hardness and friction resistance are obviously increased, and the corrosion resistance of the alloy is also improved to different degrees. In terms of overall function, micro-arc oxidation is better than anodic oxidation, and anodic oxidation is much better than chemical oxidation.
As for how to choose the right appearance treatment? It is necessary to comprehensively consider the raw materials, processing technology and use of the precision stamping parts, and choose a suitable surface treatment method for the product to make the precision stamping parts more beautiful and durable.
