How to deburr, descale, deflash, finish and polish precision aluminum alloy die casting gearbox housing

Deburring, deflashing, descaling, finishing and polishing technology for precision aluminum alloy die casting gearbox housing

Aluminum alloy die-castings are widely used in the production and manufacturing of mechanical parts in the electronics, automobile, aircraft, shipbuilding, motor, home appliance and other industries. They have the advantages of beautiful appearance, light weight, high strength and corrosion resistance. However, defects such as burrs, flash, and sharp edge often occur during the production process, so the surface finishing process of the product is particularly important. In this case, we will share a process technology and method for the automated and efficient deburring, deflashing, descaling of aluminum alloy die-casting parts for automobile gearbox housings. This polishing process solution is also suitable for the surface finishing of other die-casting parts made of soft metal materials such as zinc, magnesium, and copper.

5. Additional instructions
  • The gearbox housing is produced by high-pressure casting of aluminum alloy. The product has high precision and a smooth surface, but burrs and flashes will appear on the edges and holes of surface, which need to be polished. Therefore, a finishing process combining rough deburring, deflashing, descaling and cleaning is adopted. The rough finishing adopts a vibratory finisher with medium cutting force cone plastic media. The sharp angle of the tumbling media can reach into the grooves, corners and inner walls to remove burrs and flash.
    A vibratory polishing machine is used for cleaning. The abrasive media is made of precision finishing material without cutting force angle cut cylinder porcelain polishing media. This tumbling porcelain media has a high density and has a polishing and brightening effect, which can further reduce the surface roughness.
  • In order to improve the anti-rust performance of the product after water treatment, use a vibrating dryer with corn cob drying media to absorb moisture and dry the inner and outer surfaces.

6. Final summary
  • In this case, we demonstrated the process solution of automated deburring, deflashing, descaling and polishing of a precision die-cast aluminum product, a gearbox housing, used in the automotive parts industry.

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.
