Expert CNC Machining of Plastics Materials
From high-performance polymers like PEEK to versatile engineering plastics like Nylon and Delrin, we are experts in machining plastics to exceptionally tight tolerances. We deliver parts with superior dimensional stability, stress-free structures, and flawless finishes.
Our Comprehensive Range of Machinable Plastics
We machine plastics across all performance categories, from general-purpose to high-performance polymers.
High-Performance Plastics
These materials are designed for extreme environments requiring high temperature and chemical resistance.
PEEK (Polyether Ether Ketone)
One of the highest-performing thermoplastics. Exceptional strength, high-temperature stability, and superior chemical resistance. Ideal for aerospace components and medical implants.
PTFE (Teflon)
Famous for its extremely low friction and outstanding chemical inertness. Perfect for seals, high-purity insulators, and low-friction bushings.
Engineering Plastics
A balanced group of materials offering excellent mechanical properties and cost-effectiveness.
POM (Acetal/Delrin)
High stiffness, low friction, and excellent dimensional stability. A top choice for precision gears, bearings, and mechanical parts.
PA (Nylon)
Tough, strong, and wear-resistant. A workhorse material for functional structural components and parts experiencing friction.
PA + GF30 (30% Glass-Filled Nylon)
Reinforced with glass fibers to significantly increase stiffness and strength compared to standard Nylon. Ideal for structural parts under high loads.
PC (Polycarbonate)
Virtually unbreakable with outstanding impact resistance and optical clarity. Used for transparent housings, lenses, and protective guards.
PBT (Polybutylene Terephthalate)
Excellent electrical insulation and low moisture absorption. Common in automotive sensors and high-performance electrical connectors.
PMMA (Acrylic)
Exceptional optical clarity and weather resistance. A lightweight, shatter-resistant alternative to glass for light pipes and display windows.
General-Purpose & Olefin Plastics
Versatile, lightweight, and economical materials for various industrial and consumer applications.
ABS (Acrylonitrile Butadiene Styrene)
A versatile plastic with great impact strength and aesthetics. The standard choice for prototypes, enclosures, and consumer electronics.
PP (Polypropylene)
Lightweight and highly resistant to chemical fatigue. Excellent for fluidic components and living hinges that require repeated bending.
HDPE (High-Density Polyethylene)
Durable with high impact strength and low friction. Widely used for wear plates, fluid tanks, and chemical containers.
LDPE (Low-Density Polyethylene)
Softer and more flexible than HDPE. Known for high toughness and chemical resistance, used for flexible caps and plugs.
Mastering the Challenges of Plastic Machining
Machining plastics requires a deep understanding of material behavior. With 13+ years of experience, Jucheng has mastered the specialized techniques required to deliver perfect results.
| Challenge | Jucheng's Expert Solution | Result |
|---|---|---|
| Thermal Expansion | We account for specific expansion coefficients and machine in a temperature-controlled facility. | Parts hold tight tolerances in their real-world operating environment. |
| Material Melting | Specialized sharp tooling and optimized high-speed toolpaths manage heat at the cutting edge. | Clean, burr-free edges and preserved material integrity. |
| Internal Stress | We perform customized annealing (heat treatment) cycles for certain materials to relieve stress. | Prevents warping, cracking, or crazing over time, ensuring long-term reliability. |
| Surface Finish | Specific cutting strategies combined with professional deburring techniques. | Aesthetically pleasing parts, ready for assembly or clear-polishing. |
