About Yueyi Precision

High-Tolerance Precision Plastics CNC Machining & Engineering Polymers

At Yueyi Precision, we specialize in CNC machining of plastics and engineering polymers. Our services include machining materials such as PEEK, ABS, POM, and more, offering high-tolerance, burr-free parts used in medical, automotive, and electronics applications.
Unlike metals, plastics and polymers have unique machining challenges due to their low thermal conductivity, low melting points, and varied rigidity. We apply specialized techniques to prevent material melting, deformation, and poor surface finishes.

Our Comprehensive Plastic CNC Machining Services

As a professional CNC plastic machining manufacturer, we provide a full suite of precision CNC machining services tailored to polymeric materials — from engineering plastics like PEEK, POM and Delrin to high-performance composites. Our advanced CNC milling and turning capabilities deliver tight tolerances (±0.005mm) and consistent quality, even for complex parts.
 
We address the unique machining challenges of plastics, such as thermal deformation and surface finish, using specialized tooling and optimized techniques. This expertise makes us a reliable CNC plastic supplier for industries including aerospace, medical, automotive and electronics, supporting both prototype and production-scale projects.

Plastic CNC Machining FAQ

Q: Why is CNC machining used for plastic parts instead of just injection molding?

A: CNC machining is ideal for prototypes, low to medium volumes, or parts with extremely tight tolerances that are difficult to achieve with molding. It avoids the high cost of mold tooling and allows for rapid design iterations. For very high volumes, injection molding becomes more economical.

A: We use a combination of sharp, specialized tooling, high spindle speeds with controlled feed rates, and effective air cooling to remove heat from the cutting zone. This ensures the plastic is cleanly sheared rather than melted.

A: Absolutely. While plastics can be more challenging than metals due to thermal expansion and flexibility, we routinely hold tolerances of ±0.005 mm to ±0.1 mm on critical features for engineering-grade materials like POM and PEEK, using our controlled processes.

A: Yes. We offer a range of finishes including sanding and polishing for optical clarity, vapor polishing for acrylic, texturing, and painting or silk-screening. We also perform stress-relieving treatments for certain materials if required.
