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.
Surface Finishing Service Overview
Surface finishing plays a critical role in enhancing part performance, appearance, and durability. Our surface finishing services are designed to meet both functional and aesthetic requirements for CNC machined components.
By integrating surface treatment directly into our production workflow, we ensure consistent quality, controlled lead times, and reliable results for both prototype and production parts.
- Improve corrosion resistance and surface hardness
- Enhance visual appearance and surface uniformity
- Support functional requirements such as wear resistance and conductivity
- One-stop solution aligned with CNC machining tolerances
CNC Machined Parts Edge Options
We offer a full range of surface finishing and edge condition options for custom CNC machined parts to enhance appearance, durability, corrosion resistance, and fit-functionality.Please choose the option that suits you.
As Machined
Standard finish directly from the CNC process with visible tool marks. Suitable for functional parts and prototypes where finish is not critical.
Deburred Edge
Remove burrs to ensure smooth edges, eliminating sharp protrusions. Suitable for all parts to ensure safety and functionality.
Chamfered Edge
Deburring and edge rounding treatment give products smooth and rounded edges, which prevents interference and jamming during assembly, ensuring that components fit together smoothly and precisely.
