Shuangcheng Hardware die casting factory explain the surface treatment method of hardware die casting parts?
We should also treat the surface of the hardware before the die casting operation to see if there is oil, rust and impurities. Because the hardware die casting in the storage and transportation process, the surface will have rust, oxide skin, welding slag or dust and other dirt, so the treatment method is divided into many kinds.
Before the die casting of hardware, you should also treat its surface to see if there are oil stains, rust and impurities. As the surface of hardware die casting will be contaminated with rust, oxide skin, welding slag or dust during storage and transportation, there are also many kinds of treatment methods. The following section will introduce the surface treatment methods of Shuangcheng Hardware Die Casting Factory p>
1、 Mechanical treatment method
This method mainly includes shot blasting, shot blasting and polishing, which is also a cleaning method used by many hardware die-casting plants. Shot blasting is actually a method of accelerating the shot by centrifugal force, throwing it on the surface of the workpiece, and cleaning the rust. Everyone is familiar with the polishing method. It is a method to remove the oxide scale on the surface by high-speed rotation on the surface under the action of the motor p>
2、 Manual processing method
It is generally used for manual operation, and the tools used in the operation are grinding wheel, wire brush, scraper, etc. The oxide skin and rust on the surface of the workpiece in the hardware die casting factory can be removed, but the labor intensity of this method is very high, and the work efficiency is naturally a little low. Due to low working efficiency, the cleaning is not very clean. At present, many metal die casting plants rarely use this method p>
3、 Chemical treatment method
It is mainly to use alkaline or acid-base solution to make contact with the surface of the metal die casting, so that a lot of chemical reactions can be generated and the dirt on the surface of the metal die casting can be removed p>
The above three methods are commonly used for surface treatment of metal die castings. When operating, you can choose the appropriate treatment method according to the situation. Shuangcheng Hardware Die Casting Factory explained that these methods can make the surface of metal die castings clean, without acid and alkali residues or adhesive impurities, which is more consistent with the production needs of the metal die casting factory p>
