PC Material Properties

Property Value
Density 1.20 g/cm³
Tensile Strength 60–70 MPa
Impact Strength Extremely high (superior to PMMA)
Hardness Rockwell M 75
Heat Deflection Temperature 125–135°C
Transparency Up to 88% (nearly clear)
Flammability Self-extinguishing
Machinability Good, but heat-sensitive

PC offers higher strength than PMMA but slightly lower optical clarity—ideal for protective and structural components.

Our CNC PC Machining Capabilities

Processes

  • CNC milling (3-axis / 5-axis)
  • CNC turning
  • Pocketing, contouring, engraving
  • Complex transparent or semi-transparent shapes
  • High-strength mechanical components

Typical Tolerances

  • Standard: ±0.05 mm
  • Precision: ±0.02–0.03 mm
  • Typical surface finish: Ra 0.8–1.6 μm

Surface Finishing Options for PC

  • Flame polishing (for edges)
  • Vapor polishing (limited compatibility)
  • Manual polishing
  • Deburring & edge smoothing
  • Laser engraving / marking
  • Textured surface machining

PC can achieve high clarity, but cannot reach the optical perfection of PMMA.

Polycarbonate parts typically hold ±0.05 mm tolerances, and simpler geometries can reach ±0.02–0.03 mm.

PC is tough but sensitive to heat. If overheated, it may show stress marks or localized melting. CMS uses optimized feeds, speeds, and cooling to ensure clean, stable cuts.

Yes. PC supports flame polishing, vapor polishing (limited), and manual polishing, producing clear edges and improved transparency.

Yes. PC is far more impact-resistant—about 250× stronger than glass—but PMMA offers higher optical clarity. CMS can recommend the right material based on your application.

PC is ideal for protective covers, light diffusers, housings, guards, medical components, machine windows, and automotive lighting parts.

Yes. Polycarbonate maintains performance at 125–135°C, making it suitable for high-temperature environments.

Yes. With 60+ CNC machines, CMS handles rapid prototyping and high-volume production.

Most parts ship within 3–7 days, depending on complexity and finishing.
