High Impact & Shatter Resistance
Polycarbonate offers roughly 250 times the impact strength of standard glass and 30 times that of acrylic, making it ideal for safety guards, enclosures, and protective instrument lenses.
Optical Clarity & Vapor Polishing
Post-machining internal stress relief and specialized chemical vapor polishing restore pristine transparency for fluidic manifolds, sight glasses, light guides, and display covers.
Thermal & Dielectric Reliability
Maintains dimensional integrity between -40°C and 125°C with excellent dielectric insulation properties, suitable for electronics housings, terminal covers, and high-voltage isolators.

Surface Finishing & Optical Clarity Post-Processing
Polycarbonate is prone to micro-scratches and residual tool marks during subtractive CNC milling. Plasticpartsmfg offers specialized chemical and mechanical finishing lines in Shenzhen to achieve application-ready transparency:
- ✓ Vapor Polishing: Solvents reflow the outer micron layer, eliminating tool marks on internal channels and external surfaces without dimensional degradation.
- ✓ Optical Hand Lapping: Progressive wet sanding up to 2000+ grit followed by compounding for flat inspection windows.
- ✓ Mold Texture Standards: SPI A-1/A-2 mirror polish for clear molded parts; Mold-Tech textures (MT11010, MT11020) for matte cosmetic skins.
- ✓ Anti-Scratch & Anti-Glare Coatings: Dip or spray hard-coating for components subjected to regular wipe-downs and outdoor abrasion.
