Electropolishing
|
Shiny Metal | Stainless Steel, Metals | A process that removes a thin layer of material to create a smooth, shiny surface, often used for stainless steel parts to enhance corrosion resistance. |
Brushing
|
Metallic | Metals | Gives the surface a directional satin finish, commonly used to improve the aesthetics of metal parts. |
Polishing
|
High-Gloss | Metals, Plastics | Achieves a mirror-like finish, commonly used for both aesthetic appeal and to enhance optical clarity on transparent parts. |
Electroplating
|
Silver, Gold, Nickel | Metals | Coats parts with a thin layer of another metal (e.g., nickel, chrome) to improve appearance and corrosion resistance. |
Black Oxide
|
Black | Steel, Iron | Provides a thin, durable black finish for ferrous metals, improving corrosion resistance while maintaining the part’s dimensions. |
Passivation
|
N/A | Stainless Steel | Cleans and protects stainless steel surfaces by removing contaminants and enhancing corrosion resistance. |
Heat Treatment
|
