Surface Finish Service
FastPreci uses dozens of surface treatment processes to improve the corrosion resistance, wear resistance, appearance and other performance of CNC machined parts to meet the requirements of different application conditions.
Common Types of Surface Treatment
| Finish Type | Applicable Materials | Description | |||||||||||
| As machined | Metal, plastic | Roughness of approx. 3.2 μm (126 μin) removes burrs and sharp edges. | |||||||||||
| Electroplating | Metal | Deposits metal to improve corrosion resistance, hardness and appearance. | |||||||||||
| Anodizing | Metal | 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 aesthetics. | |||||||||||
| Painting | Metal, plastic, ceramic, Composite materials | The spray gun evenly applies liquid paint for a smooth, shiny 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. | |||||||||||
| Black Oxide | Metal | Produces a black or dark oxide film that increases corrosion resistance, abrasion resistance and oxidation resistance to enhance 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, uniform coating and strong adhesion. | |||||||||||
| Passivation | Metal | Forms an oxidized protective film to improve corrosion resistance. | |||||||||||
| Alodine | Metal | Transparent protective coating for improved corrosion resistance and surface hardness. | |||||||||||
| Chromate | Metal | Formation of passivation film for enhanced corrosion and oxidation resistance | |||||||||||
| PVD | Metal, ceramic, plastic | The paint evaporates and condenses to form a thin film, improving abrasion resistance, corrosion resistance and aesthetics. | |||||||||||
| CVD | Metal, ceramic | The chemical reaction forms a thin film that improves abrasion resistance, high temperature resistance and corrosion 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. | |||||||||||
| Polishing | Metals, plastics, ceramics | Rubbing or grinding surfaces to enhance smoothness and brilliance. | |||||||||||
| Silk Screen | Metal, plastic | The ink is embossed through a screen to print patterns and text. | |||||||||||
| Laser Engraving | Metal, plastic | The laser beam heats, melts or evaporates to mark, engrave or pattern engraving. | |||||||||||
