Why Polycarbonate (PC)?
High-transparency, impact-resistant custom parts for medical, automotive, and optical industries.
Optical Clarity
Achieves up to 90% light transmission, ideal for lenses, light guides, and sight glasses.
Impact Resistance
Virtually unbreakable; offers 250 times the impact strength of glass.
Heat Resistance
Maintains structural integrity up to 135°C (275°F).
Dimensional Stability
Low moisture absorption ensures tight tolerances for complex mechanical assemblies.
Polycarbonate Technical Properties
Engineered for durability, transparency and heat resistance — verified with in-house material testing.

Customer Feedback
Rated Excellent by procurement leaders & design engineers worldwide
“Allied Metal delivered optical-grade polycarbonate covers with flawless clarity. Vapor polishing exceeded our expectations. Fast turn and great DFM support.”
— Sarah K., Senior ME, Automotive Tier 1
“We switched to Allied for our medical device enclosures. Their polycarbonate machining quality, consistent tolerances, and quick prototyping saved us 3 weeks.”
— Dr. James L., R&D Director, MedTech
“Excellent communication, flexible with small batch runs. The 5-axis machining on complex PC brackets was flawless. Will continue long-term partnership.”
— Marco R., Procurement Manager, Industrial Automation
FAQs
Yes. Standard machining leaves a translucent finish. We offer Vapor Polishing and Manual Buffing to restore 100% optical transparency for lenses and sight glasses.
We use stress-relief annealing and plastic-specific sharp carbide tools. This eliminates the “crazing” or cracking often seen in poorly processed PC parts.
We typically hold ±0.05mm. For high-precision medical or aerospace components, we can achieve ±0.01mm depending on the geometry.
CNC: Best for < 500 units, rapid prototyping, and thick-walled designs.
Molding: Best for high-volume production where you can offset the mold cost.
Yes. We frequently machine GF20/GF30 PC for industrial parts requiring higher rigidity and heat resistance than standard PC.
Always. Every quote includes a free Design for Manufacturing review to help you reduce tool changes and lower your per-part cost.
