What is mechanical galvanizing

In a rotating drum containing plated parts, glass balls, zinc powder, water, and accelerators, the glass balls, as the impact medium, rotate with the drum and generate mechanical and physical energy through friction and hammering with the surface of the plated parts. Under the action of chemical accelerators, the coated zinc powder is "cold welded" to the surface of the plated parts, forming a smooth, uniform, and fine coating with a certain thickness.
