Deburring,descaling and polishing method of copper alloy die castings (floor sockets)
How to chamfer, deburr, descale, polish and brighten copper alloy die castings?
Copper alloy die casting is a mature and versatile production process, which is used to manufacture a variety of hardware parts products. Commonly copper alloys include copper-aluminum alloy, copper-zinc alloy, copper-nickel alloy, etc. Die casting products will produce burrs, flash, scratches, oxide scale and other defects during the production process. Do you know what kind of finishing and polishing process copper alloy die castings need to go through to obtain a satisfactory surface effect? In this case, we will share a copper alloy floor socket deburring, descaling, polishing, brightening process technology and methods. This polishing process solution is also suitable for the surface polishing of brass, zinc alloy, aluminum alloy, magnesium alloy and other products.

5. Additional instructions
-
Copper alloy floor outlets have low hardness and are medium-sized product parts with a large daily processing quantity. Therefore, a vibratory polishing machine is used with a cone plastic media with low hardness to perform rough finishing. The conical tip can touch deep into the groove to remove burrs and chamfers.
Fine polishing and brightening is also achieved by using a vibrating finishing machine, with spherical white corundum finishing media with high hardness and light cutting force, which can cut a small amount, further reduce the roughness and improve the surface brightness. - In order to improve the anti-rust and anti-corrosion performance of the product after water treatment, it is immersed in the anti-rust liquid for anti-rust treatment after polishing. Finally, a vibrating dryer is used to dry the surface moisture and dry it.
6. Final summary
- In this case study, we demonstrate the process of chamfering, deburring, descaling and polishing the surface of a copper alloy die-casting component, a floor socket.
