PC
Polycarbonate combines transparency and high impact strength for protective covers, optical parts and heat-resistant housings.
Discuss clarity, impact and finishing as one decision
For a protective cover or PC housing, tell Aria which surfaces must be clear, which features control assembly and what the component will encounter in use. We help you review the grade and finishing requirements together. Cleaning agents, coatings and appearance criteria belong in that discussion before production.
Aria offers both machined and injection-molded PC components. You can discuss the prototype and repeat-production requirements together, including the viewing surfaces and acceptance requirements for each stage.

CNC Milling Services: Injection molding after thorough drying; the supplied guidance gives 120°C for at least four hours as a reference. CNC milling and turning of sheet or rod. Choose cleaning, paint and adhesive systems that avoid stress cracking. Dry before molding to prevent hydrolysis; select UV protection outdoors and hard coating when scratch resistance matters. 3-axis milling, 4-axis milling, 5-axis milling: Use a machinable stock grade; geometry, workholding and material condition determine feasibility.

Advantages and considerations
Advantages
Light transmission around 89%, good toughness, dimensional stability and electrical insulation. Representative heat-deflection temperatures are around 125°C, depending on grade and load.
Material limitations
Solvents and strong alkalis can cause stress cracking. Untreated PC scratches and can yellow under UV exposure; notches and combined mechanical/chemical stress need attention.
How Aria supports your project
Help choosing a material

Inspection to your drawing
Dimensional checks and inspection reports for the critical features on your drawing.
Compatible surface finishes
Selection requirements
- Laser engraving · Painting
Choose cleaning, paint and adhesive systems that avoid stress cracking. Dry before molding to prevent hydrolysis; select UV protection outdoors and hard coating when scratch resistance matters. Painting, hard coating, printing, vacuum metallization and laser engraving. Use compatible adhesive systems.
- Pad printing · Silk screening
Adhesion depends on polymer grade, surface preparation and coating or ink chemistry. Confirm with the selected formulation.
- Glossy · Semi-glossy · Matt · Textured
Mold-transferred appearance depends on the resin and tool surface; gloss and texture do not specify a material-independent roughness.
