    Options for the Finish of CNC stainless steel parts

  • Passivation: This type of chemical treatment takes away any free iron left on the surface and thus helps to protect the surface from corrosion whereby the surface has no additional thickness and remains smooth and shiny.
  • Electropolishing: Achieves ultra fine or mirror electric finishes by means of using an electric current together with a chemical bath to remove a controlled thin coating of the base material.
  • Powder Coating: The powdered paint is applied electrostatically, after which, thick and smooth coatings of paints are cured. It does alternate dimensions of the part, hence masking would be required for tight tolerances.
  • Media Blasting: Use of compressed air together with abrasive particles to remove surface contaminants and also alter the surface texture for even matte uniformly. It is mostly used together with other types of finishes to enhance the appearance.
  • Tumbling. Thermal barrel finishing is burial of parts in a barrel with some abrasive movement and motion that makes the parts achieve a smooth finish, aims for the removal , sharp edges and burrs.
  • Black Oxide: This Forms a layer of magnetite on ferrous products thereby creating a rust inhibition coating and improves the appearance of the product in a matte texture.
  • Zinc Plating: Acts as a barrier to corrosion to steel wherein zinc is coated either by means of electro-galvanization or hot-dip galvanization.
