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 involves depositing a thin layer of metal onto the surface of the part. This can be used to enhance the appearance of the part, increase its resistance to corrosion, or improve its conductivity.
Powder coating:
Powder coating involves applying a dry powder to the surface of the part and then curing it in an oven. This creates a durable, scratch-resistant finish that can be customized in a variety of colors.
Painting:
Painting is a common surface treatment for CNC machined parts, and it can be used to add color or a protective coating to the surface. Paints can be applied in a variety of finishes, from matte to glossy.
Sandblasting:
Sandblasting involves using abrasive particles to remove material from the surface of the part. This creates a uniform, matte finish and can be used to prepare the surface for other surface treatments or to remove surface imperfections.
Polishing:
Polishing involves using abrasive pads or compounds to smooth and shine the surface of the part. This can be used to create a mirror-like finish or to prepare the surface for other surface treatments.
Laser etching:
Laser etching involves using a laser to remove material from the surface of the part, creating a permanent, high-contrast mark or design.
