provide wide range CNC metal machined parts and plastic parts surface treatment
metal surface finishing
Metal Surface Finishing Service
Surface treatment is done by changing the mechanical, physical, and chemical properties of the surface layer of the product to meet the requirements of corrosion resistance, wear resistance, decoration, or other special functions of the product.
RALLY offers high-quality surface finishing services for all metal parts and plastic products. We have skilled specialists and a long-standing stable of brother factories that can provide perfect surface finishes for your prototypes and other components. We are subdivided according to two different materials: metal and plastic.
Metal Surface finishing
Mechanical Surface Finishing
Mechanical surface treatment mechanically alters the surface properties of a workpiece to make it smoother, flatter, or thicker. Common types are Polishing, Grinding, Blasting, etc.
Chemical Surface Finishing
Chemical surface finishing modifies the surface of metals through the use of chemicals. Common types: Plating, Black Oxide, Phosphating, Galvanizing, Anodizing, Pickling, Passivation, etc.
Electrochemical Surface Finishing
Electrochemical surface treatment or electrolytic polishing treatment is a finishing process that uses a combination of electricity and chemical substances to polish the surface of metal parts.

Plastic surface finishing
There are many common surface processing processes of plastic products, among which electroplating and spray painting are relatively common ways, the following comprehensive introduction of the plastic surface treatment process:
A process of printing the desired pattern on the surface of plastic parts by pad printing, screen printing, transfer printing, and other methods.
Applied to plastic surfaces to obtain a metallic finish and achieve the functional requirements of metals. Includes chemical plating and electroplating.
A coating is attached to the surface of plastic products to form a coating film, which protects and decorates the product. Generally, we use spray paint.
Removal of materials
The process of removing material from plastic parts includes wire drawing, laser engraving, sandblasting, and polishing.
