Is Dry Electropolishing Better?
Metals represent shine. Ant metallic surface we come across daily is shiny. But they are not as lustrous as they look; the process of electropolishing makes the metal shine.
Electropolishing removes a thin layer of metal to give the metal a smooth finish using electricity and chemicals.
How does Electropolishing work
Metal is immersed in an acidic liquid, where the metal serves as the positively-charged anode and the liquid as the negatively-charged cathode.
In a dry electropolishing machine, the liquid is replaced by sponge-like solid spheres, acting as the anode. These move with continued planetary rotation and work on the metal immersed. The current passed oxidizes the outer surface of the metal and is absorbed by the beads when they come in contact. The bumps in the surface are removed this way, and the metal surface s left shiny.
- It is safer and less hazardous than the acid liquid used in the traditional process.
- It is also more reusable than acid and hence environmentally friendly.
- The finish is very commendable, and it delivers a mirror finish.
- It is well suited for products with very intricate cuts.
- It leaves the metal highly corrosion resistant.
- Disposal of waste is relatively easy.
New technologies promise better results and eliminate the shortcomings of the previous process. Dry electropolishing is similarly a hassle-free process to working with hazardous concentrated acids. The finish is also perfect and shiny, then why not adapt to the newer technologies.
