Surface Treatment
(CNC Machined Parts Surface Treatment)

Anodizing: Anodizing is an electrochemical process that creates a layer of oxide on the surface of aluminum and other metals. It enhances the corrosion resistance and wear resistance of the parts and can also be used to add color to the surface.

Plating: Plating is the process of adding a thin layer of metal to a part's surface to enhance its appearance, increase corrosion resistance, or improve conductivity.

Powder Coating: Powder coating is a process that involves applying a dry powder to a part's surface and then curing it in an oven to create a durable finish. This finish is scratch-resistant and available in a variety of colors.

Painting: Painting can be applied to CNC machined parts to add color or a protective coating in a variety of matte to glossy finishes.

Sandblasting: Sandblasting is a process that utilizes abrasive particles to remove material from a surface. This method creates a uniform, matte finish and can be applied to prepare the surface for other surface treatments or to eliminate surface imperfections.

Polishing: Polishing is the process of using abrasive pads or compounds to smooth and shine a surface. This can be done to achieve a mirror-like finish or prepare the surface for other treatments.

Laser Etching: Laser etching is the process of using a laser to remove material from the surface of a part to create a permanent high-contrast mark or design.
