Surface Treatment of Plastics
| Surface Finish | Surface Finish Description | CNC Parts Appearance | |||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
| Machining Surface Finishes | Parts are machined and deburred, with sharp edges chamfered. Visible machining marks and slight surface scratches. | Depends on the material | |||||||||
| Polishing | A method to reduce surface roughness and achieve a bright, smooth surface. The polishing process ranges from Ra 0.8 to Ra 0.1. | Achieves a smooth surface or mirror finish, also used for matte finish | |||||||||
| Sandblasting | Uses compressed air to propel abrasive material onto the surface for cleaning or grinding. | Can be matte, semi-gloss, or glossy, usually without specific color | |||||||||
| PVD | A thin film of metal, metal compounds, or ceramics is deposited on the surface to enhance hardness, corrosion resistance, and aesthetics. | Various colors | |||||||||
| Titanium Nitride Coating | A layer of titanium nitride is deposited to improve hardness and wear resistance. | Gold, black | |||||||||
| Chromium Nitride Coating | Chromium nitride is deposited onto the surface to enhance hardness and wear resistance. | Silver | |||||||||
| Powder Coating | Fine powders of pigment and resin are sprayed onto the surface to form a uniform coating, providing corrosion resistance, wear resistance, and decorative effects. | Various colors (depends on powder color) | |||||||||
| Painting | Liquid paint is applied to the surface to provide protection and decoration. | Various (depends on paint color) | |||||||||
| Laser Marking | A laser beam create high-precision markings or engravings on the surface. | Various (depends on material) | |||||||||
| Heat Transfer Printing | Patterns are transferred from transfer paper to plastic using heat and pressure. | Can achieve complex patterns and color effects | |||||||||
