Product Overview
Polycarbonate (PC) plastic CNC machining delivers precision-engineered components from one of the toughest and most versatile transparent thermoplastics available. Polycarbonate offers an exceptional combination of properties, including outstanding impact strength (up to 900 J/m), excellent optical clarity (88-91% light transmission), and high heat resistance with a glass transition temperature of 147°C. Its unique balance of transparency, toughness, and dimensional stability makes it ideal for critical applications across safety equipment, optics, electronics, automotive, aerospace, and medical device industries.
Our advanced CNC machining capabilities enable us to produce custom polycarbonate parts with exceptional precision and consistent optical quality. Using state-of-the-art CNC milling and turning centers with specialized tooling for transparent plastics, we manufacture complex geometries, intricate optical features, and tight-tolerance components that maintain the material's clarity and mechanical integrity. Our experienced engineering team collaborates with you throughout the entire process, from material grade selection and design optimization to final delivery, ensuring your polycarbonate parts meet the highest optical and mechanical standards.
We offer comprehensive finishing options for your polycarbonate parts, including optical polishing (achieving up to 92% light transmission), anti-reflective coating, UV-resistant hard coating for outdoor applications, flame retardant treatments (UL94 V-0 achievable), dyeing in various translucent and transparent colors, and precision assembly. These finishes enhance both optical performance and functional properties, providing improved scratch resistance, weatherability, and flame safety. With fast delivery options and no minimum order quantity, we're ready to meet your production needs, whether you require rapid prototypes or large-scale production runs for safety-critical applications.

Frequently Asked Questions
What is the minimum order quantity for polycarbonate parts?
We have no minimum order quantity. Whether you need a single optical prototype or thousands of production parts, we can accommodate your requirements with the same level of precision and optical quality.
What is the typical lead time for polycarbonate parts?
Prototype orders typically ship within 3-5 business days. Production orders usually take 7-14 days depending on quantity, complexity, and optical requirements. Expedited options are available for urgent requirements.
What surface finish options are available for polycarbonate parts?
We offer optical polishing (achieving up to 92% light transmission), anti-reflective coating, UV-resistant hard coating for outdoor applications, flame retardant treatments, dyeing in transparent/translucent colors, and precision assembly. Each finish provides different optical and functional benefits.
Is polycarbonate suitable for outdoor applications?
Yes, polycarbonate has excellent weatherability. For extended outdoor use, we recommend UV-resistant hard coating to prevent yellowing and maintain optical clarity. Polycarbonate's high impact resistance makes it ideal for outdoor safety glazing and protective equipment.
Can polycarbonate achieve flame retardant certifications?
Yes, polycarbonate is inherently flame retardant and can achieve UL94 V-0 rating without additives. This makes it suitable for aerospace, transportation, and electronics applications requiring strict flame safety standards.
What is the difference between polycarbonate and acrylic?
While both are transparent thermoplastics, polycarbonate has significantly higher impact strength (250x that of glass) and heat resistance (147°C vs 100°C). Acrylic offers slightly better optical clarity (92% vs 91%) and UV resistance, but is much more brittle. Polycarbonate is preferred for safety-critical applications requiring impact resistance.
