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
UV Treatment	UV curing technology is used to treat plastic surfaces, enhancing their wear resistance, chemical resistance, and weather resistance.	Smoother and more even
Cleaning	Effectively eliminates grease, oil, and various contaminants from surfaces.	Free of dust and grease
