| Finish Type | Applicable Materials | Description & Functional Benefits |
|---|---|---|
| As Machined | Metal, Plastic | Roughness of approx. 3.2 μm (126 μin); removes burrs and sharp edges for a standard industrial finish. |
| Electroplating | Metal | Deposits metal layers to improve corrosion resistance, surface hardness, and overall aesthetic appearance. |
| Anodizing | Metal (Primarily Aluminum) | Forms an oxide film to improve corrosion resistance, hardness, abrasion resistance, and aesthetics. |
| Powder Coating | Metal | Powder coated and cured to enhance corrosion resistance, impact resistance, and provides a durable aesthetic finish. |
| Painting | Metal, Plastic, Ceramic, Composite | The spray gun evenly applies liquid paint for a smooth, shiny, and customized color surface. |
| Brushing | Metal | Forms a continuous fine texture to improve appearance, slip resistance, and reduce light reflection. |
| Sand Blasting | Metal, Plastic, Ceramic | Abrasives are sprayed onto surfaces to clean, polish, or increase surface roughness for better coating adhesion. |
| Black Oxide | Metal | Produces a black or dark oxide film that increases corrosion, abrasion, and oxidation resistance while enhancing appearance. |
| Teflon Coating | Metal, Plastic, Ceramic | Forms a Teflon film for improved corrosion resistance, high temperature resistance, and low friction performance. |
| Electrophoretic | Metal | Even deposition of paint through electrical current, providing a uniform coating and strong adhesion. |
| Passivation | Metal (Stainless Steel) | Forms an oxidized protective film to significantly improve corrosion resistance by removing surface iron. |
| Alodine | Metal (Aluminum) | Transparent protective coating for improved corrosion resistance and surface hardness without changing dimensions. |
| Chromate | Metal | Formation of a passivation film specifically for enhanced corrosion and oxidation resistance. |
| PVD | Metal, Ceramic, Plastic | Physical Vapor Deposition; the paint evaporates and condenses to form a thin film, improving abrasion resistance and aesthetics. |
| CVD | Metal, Ceramic | Chemical Vapor Deposition; chemical reaction forms a thin film that improves abrasion and high temperature resistance. |
| Electroless Plating | Metal, Plastic | Homogeneous deposition of metallic coatings to improve corrosion resistance, abrasion resistance, and electrical conductivity. |
| Electropolishing | Metal | Electrolysis removes minor surface imperfections and enhances smoothness and brilliance for a mirror-like finish. |
| Polishing | Metals, Plastics, Ceramics | Mechanical rubbing or grinding of surfaces to enhance smoothness and brilliance. |
| Silk Screen | Metal, Plastic | The ink is embossed through a screen to print precise patterns and text onto the component. |
| Laser Engraving | Metal, Plastic | The laser beam heats, melts, or evaporates material to mark, engrave, or create pattern engraving with high precision. |
