Surface Finish Capabilities
We offer 15+ surface finishing options tailored for custom components. From initial production to final surface refinement—ensuring your parts meet the most stringent functional and aesthetic standards.
A. Mechanical Finishes
Physical treatments to refine surface texture, eliminate tool marks, and enhance tactile quality.
| Surface Finishes | Description | Compatible Materials | Service | Cosmetic Availability | Tolerances |
|---|---|---|---|---|---|
| Bead Blasting | Propels glass or ceramic beads to create a uniform matte or satin finish; ideal for removing tool marks. | Metals, Plastics | CNC & Die Casting | On Request | Negligible impact |
| Brushing | Creates a distinct directional grain texture on the surface for a high-end, industrial metallic look. | Metals | CNC Machining | Always Cosmetic | No impact |
| Polishing (Mirror) | Mechanical buffing with fine abrasives to achieve a highly reflective, mirror-like aesthetic. | Metals | CNC & Die Casting | Always Cosmetic | Met after process |
| Tumbling | A vibratory or barrel process used to smooth, debur, and clean high-volume batches of parts. | Metals, Plastics | CNC & Die Casting | Semi-cosmetic | Minimal edge radiusing |
| Smooth Machining | Utilizing high-precision tool paths and feeds to achieve superior surface smoothness. | Metals, Plastics | CNC Machining | No (Functional) | No impact |
B. Chemical & Electrochemical Treatments
Surface chemistry modification for extreme corrosion resistance, hardness, and decorative coloring.
| Surface Finishes | Description | Compatible Materials | Service | Cosmetic Availability | Tolerances |
|---|---|---|---|---|---|
| Anodizing (Type II) | An electrochemical oxide layer that provides decorative protection; available in various custom colors. | Aluminum, Titanium | CNC Machining | Excellent | Minor build-up (5-25μm) |
| Hard Anodizing (Type III) | Creates a thick, ceramic-like wear-resistant layer designed for high-friction industrial applications. | Aluminum | CNC Machining | Functional | Build-up (25-50μm) |
| Chromate Conversion | Also known as Alodine; provides a protective film while maintaining surface electrical conductivity. | Aluminum, Magnesium | CNC & Die Casting | No | No measurable impact |
| Passivation | A chemical treatment for stainless steel that removes surface contaminants to maximize rust resistance. | Stainless Steel | CNC Machining | No | No impact |
| Black Oxide | A chemical conversion that creates a sleek, matte black finish with excellent dimensional stability. | Steel, Copper | CNC Machining | Semi-Cosmetic | Zero build-up |
C. Coating & Painting
High-performance protective layers designed for environmental shielding or branding requirements.
| Surface Finishes | Description | Compatible Materials | Service | Cosmetic Availability | Tolerances |
|---|---|---|---|---|---|
| Powder Coating | A durable, heat-cured dry powder finish available in a massive range of colors and textures. | Metals | CNC & Die Casting | High (Decorative) | 50-100μm build-up |
| E-Coating | Electrically applied paint that ensures 100% coverage and rust protection for complex die-cast parts. | Metals | Die Casting | Functional/Cosmetic | 15-30μm build-up |
| Teflon (PTFE) | A specialized non-stick coating for parts requiring low friction, high lubrication, or heat resistance. | Metals | CNC Machining | Functional | Minimal build-up |
| PVD Coating | Vacuum deposition for ultra-hard, luxury metallic films in colors like Gold, Rose Gold, or Gunmetal. | Metals | CNC & Die Casting | Always Cosmetic | Ultra-thin (<5μm) |
D. Plating & Specialized Marks
Electro-deposited metal films and precision marking for branding and functional enhancement.
| Surface Finishes | Description | Compatible Materials | Service | Cosmetic Availability | Tolerances |
|---|---|---|---|---|---|
| Electroplating | Zinc, Nickel, or Chrome plating via electrolysis for enhanced hardness and superior corrosion protection. | Metals | CNC & Die Casting | Yes (Shiny/Matte) | 5-15μm build-up |
| Laser Etching | High-precision laser marking for permanent logos, serial numbers, branding, or QR codes. | Metals, Plastics | CNC & Die Casting | Always Cosmetic | Zero impact |
