Surface Finishing Capabilities
We provide a comprehensive range of surface finishing services to improve corrosion resistance, wear performance, and visual appearance of CNC machined parts. Suitable for both functional and cosmetic requirements.
Deburring & Edge Rounding
Removes sharp edges and burrs from parts to improve safety, performance, and assembly compatibility.
Polishing
Produces smooth or mirror-like surfaces for decorative parts and reduced surface friction.
Sandblasting
Creates a uniform matte surface and removes machining marks, commonly used as a pre-treatment before anodizing or coating.
Anodizing
Enhances corrosion resistance and appearance of aluminum parts, available in clear and multiple color options.
Electroplating
Applies zinc, nickel, or other metal coatings to improve corrosion resistance and surface durability of steel components.
Conversion Coating
Provides a protective oxide layer for aluminum, enhancing corrosion resistance and paint adhesion.
Spray Coating
Applies a uniform coating to improve wear and corrosion resistance, suitable for functional and decorative finishes.
Laser Marking
Uses laser technology to engrave precise markings, serial numbers, and logos on metal or plastic surfaces.
