CNC Machining in PC Material
At Jiangzhi, we specialize in cnc machining polycarbonate components with high precision and superior clarity. Whether you require transparent prototypes or robust structural machining polycarbonate parts, we deliver high-quality PC CNC parts.
Thanks to polycarbonate excellent impact resistance and optical transparency, CNC machined PC parts are widely used in medical devices (like protective covers or light diffusers), electronics (transparent enclosures and lenses), automotive (light covers or housings), and aerospace (shields and panels). Our team ensures smooth processing of PC plastic, overcoming machining challenges like melting or cracking. From material selection to surface finishing, we provide a tailored, start-to-finish solution.

Advantages & Disadvantages of PC CNC Machining
Advantages
- Extremely high impact resistance – almost unbreakable, ideal for demanding use.
- Optical clarity – excellent light transmission, perfect for clear parts.
- Dimensional stability – maintains precision even under stress.
- Good thermal resistance – suitable for moderately high temperatures.
Disadvantages
- More challenging to machine – higher melting point, tendency to chip without proper tooling.
- Surface scratching – PC scratches more easily than acrylic or PET.
- Requires post-processing – for optical-grade finishes or smooth transparency.
- UV sensitivity – needs coating for prolonged outdoor use.
Surface Finishing Options for CNC Machined Parts
Standard finish with visible tool marks; suitable for functional prototypes and internal components.
Uses abrasive media to create a uniform matte or satin finish; also improves coating adhesion on plastic or metal surfaces.
Adds logos, text, or identification marks via silk screen or pad printing, ideal for branding or part tracking.
Removes machining marks and evens out surface texture; ideal for prototypes and parts where appearance is not critical.
Painting and powder coating provide colorful, durable, and corrosion-resistant finishes.
Deposits metal layers such as nickel or chrome on parts, improving wear resistance, conductivity, and aesthetic quality.
Produces a smooth, glossy finish; commonly applied to plastics like PC or PMMA for enhanced clarity and premium look.
Chemical treatment for ferrous metals, creating a dark, corrosion-resistant surface with minimal thickness.
Electrochemical process for aluminum that enhances corrosion and wear resistance, with options for colored finishes.
Jiangzhi PC CNC Machining Parts Are Guaranteed
Yes, especially for strong, transparent parts. It requires proper tools and speeds, but results are excellent.
PC can handle temperatures up to ~135°C. It’s more heat-resistant than ABS but less than materials like PEEK.
PC is tougher and more impact-resistant. Acrylic offers better scratch resistance and optical clarity but is more brittle.
Yes, CNC machined PC can be polished to near-optical clarity with the right finishing processes.
PC CNC machining is faster and more flexible for low volumes or complex geometries. PC molding is better for mass production.
