For machinery, fabrication lines, automation systems, and protective devices, polycarbonate CNC machined parts provide both mechanical strength and protection without adding excessive weight. This makes them suitable for applications where consistent performance under stress and exposure to chemicals or temperature changes is critical.
At Chiheng, we specialize in precision CNC machining of polycarbonate components for industrial use. With over 17 years of experience, advanced CNC equipment, and skilled machinists, we deliver parts with tight tolerances and excellent surface finishes. Our manufacturing capacity covers everything from prototypes to full-scale production, ensuring each part meets the exact requirements of your design and application. As a trusted polycarbonate milling parts supplier, we help industrial clients worldwide achieve high-quality, custom-made solutions for their equipment.
| Material | Comparison with Polycarbonate (PC) |
| Acrylic (PMMA) | PC is stronger and less likely to crack when machined. |
| Metals (Aluminum, Steel) | PC is lighter, corrosion-free, and easier to machine. |
| ABS / PVC | PC offers better clarity, toughness, and heat resistance. |
| Nylon (PA) | PC has greater dimensional stability and transparency. |
| Delrin (POM/Acetal) | PC is tougher and clearer but less smooth to machine. |
| PETG | PC is stronger, more heat resistant, and more durable. |
| PTFE (Teflon) | PC is far more rigid and better for structural parts. |
| Glass | PC is lighter, impact resistant, and easier to cut or drill. |
Polycarbonate is a tough, versatile plastic, but its unique properties require a specialized approach to prevent common issues like cracking, warping, and poor surface finish. At Chiheng, our precision CNC milling technology is specifically optimized to handle these challenges. We utilize high-speed 3-axis, 4-axis, and 5-axis CNC milling machines with sharp carbide tools and custom feed rates, ensuring every part is cut cleanly and accurately.
Our team is capable of holding extremely tight tolerances, down to ±0.005mm (0.0002 inches), ensuring every part is consistent and ready to drop into your final assembly without modification. From intricate small components to large structural pieces, we can machine parts ranging from a few millimeters to over a meter, handling everything from simple flat profiles to complex 3D geometries with internal pockets, slots, and contours.
Our CNC plastic milling services are tuned for:
Our optimized setup allows us to produce custom polycarbonate parts with smooth, stress-free edges and exceptional repeatable accuracy for multi-part production runs. This capability is why global manufacturers trust us to deliver precision, durability, and quick turnarounds on their most demanding projects.
To achieve a flawless, transparent, and durable finish after CNC machining, parts require specialized post-processing. Polishing and other surface finishes aren’t just for aesthetics; they are crucial for enhancing performance and protecting the parts from demanding industrial environments.
| Finish Type | Application & Benefits | How It Works |
| Vapor Polishing | Creates a high-gloss, crystal-clear finish. Ideal for intricate parts like windows, lenses, or protective covers where clarity is critical. | Uses a solvent vapor to microscopically melt the surface, smoothing out tool marks and creating a uniform, transparent surface. |
| Flame Polishing | Best for a glass-like finish on flat or simple edges. Quick and effective for achieving a high-gloss look on straight surfaces. | A controlled flame is passed over the surface, quickly melting and sealing it to remove machining marks and imperfections. |
| Bead Blasting | Produces a consistent matte or satin texture. Excellent for non-reflective surfaces like control panels or casings where glare needs to be reduced. | Tiny beads are propelled at the part, creating a uniform, textured finish that diffuses light. |
| Protective Coatings | Enhances durability. Used to improve scratch resistance, add UV protection, or increase chemical resistance for parts in harsh environments. | A specialized liquid coating is applied and cured onto the part’s surface, forming a protective layer. |
Polycarbonate CNC parts are used across a wide range of industrial equipment setups because they’re tough, lightweight, and easy to shape to exact specs. In most cases, they replace heavier metal parts or more brittle plastics.
