All finishes
The raw surface left directly by the cutting tool. Fast, low cost, standard tolerance.
Learn more →A matte, uniform texture created by blasting fine abrasive media onto the part.
Learn more →An electrochemical process that removes a thin layer of metal, leaving a smooth, bright surface.
Learn more →Controlled heating and cooling to change the metal's hardness and strength.
Learn more →A chromate conversion coating for aluminum that adds corrosion protection and a base for paint.
Learn more →An electrochemical coating on aluminum that creates a hard, colored, corrosion-resistant layer.
Learn more →A chemical conversion coating that gives steel a black, slightly matte finish.
Learn more →Chemical plating (often nickel) that coats complex shapes evenly without electricity.
Learn more →Electrically depositing a metal layer (nickel, chrome, gold) onto the part surface.
Learn more →A chemical treatment that removes free iron from stainless steel to boost corrosion resistance.
Learn more →Dry powder is electrostatically applied then cured to a tough, durable finish.
Learn more →A water-based coating applied with an electric field for even coverage.
Learn more →Standard mold surface grades (A1-D3) that control the gloss of molded plastic parts.
Learn more →Molten material is sprayed onto the part to build a thick protective coating.
Learn more →A coating method using an electric field to deposit paint evenly, including into recesses.
Learn more →Chemical reduction deposits a metal layer evenly without electric current.
Learn more →A chemical conversion coating that prepares steel for painting or adds corrosion resistance.
Learn more →An ultra-thin protective coating applied at the nano scale for special surface properties.
