Looking for high-precision parts that blend strength, low friction, and cost-effectiveness? Our Polyoxymethylene (POM) CNC Machining services deliver top-tier results—from custom prototypes to high-volume production. Whether for automotive components, medical devices, or industrial equipment, we turn durable acetal resin into precise, reliable parts that meet tight tolerances and strict quality standards.
What Is Polyoxymethylene (POM) CNC Machining?
Polyoxymethylene (POM), also known as acetal resin, is a high-performance thermoplastic and engineering polymer prized for its exceptional mechanical properties. Its unique chemical structure—composed of repeating oxymethylene units—gives it high strength, rigidity, and resistance to wear and chemicals.
CNC Machining (Computer Numerical Control Machining) is a subtractive manufacturing process that uses computerized tools to shape materials with unmatched precision. When combined, POM CNC Machining leverages the polymer’s natural advantages to create complex, dimensionally stable parts for diverse industries. Below is a breakdown of POM’s key mechanical properties that make it ideal for CNC machining:
| Mechanical Property | Typical Value (ASTM Standard) | Key Benefit for CNC Machining |
| Tensile Strength | 60 MPa (ASTM D638) | Enables creation of strong, load-bearing parts |
| Flexural Modulus | 2.8 GPa (ASTM D790) | Ensures rigidity in precision components |
| Impact Strength | 6 kJ/m² (ASTM D256) | Resists breakage during machining and end-use |
| Coefficient of Friction | 0.15 (vs. steel, dry) | Reduces wear on tools and finished parts |
| Heat Deflection Temperature (HDT) | 110°C (ASTM D648, 1.82 MPa) | Maintains shape in high-temperature environments |

Process: How We Execute POM CNC Machining
The POM CNC Machining process at Yigu Technology follows a structured, step-by-step approach to ensure precision and efficiency. Each stage is optimized to leverage POM’s properties while minimizing waste and errors:
- Design & Programming: Our engineers convert your 3D models into CNC-compatible code, optimizing tool paths for POM’s machinability. This step ensures programming accuracy to avoid material waste.
- Setup: We prepare the CNC turning or CNC milling machines, installing the appropriate cutting tools (e.g., high-speed steel or carbide tools) for POM. Proper setup is critical to achieving tight tolerances.
- Machining: The machine executes the program, performing drilling, cutting, and other operations to shape the POM material. We monitor the process in real time to address any issues.
Inspection: After machining, parts undergo rigorous inspection using precision tools (e.g., calipers, micrometers) to verify dimensional accuracy and adherence to specifications.
Materials: Choosing the Right POM for Your Project
Not all POM materials are the same—selecting the right type is key to achieving optimal performance. We offer a range of POM (Polyoxymethylene) variants, each with unique properties suited to specific applications:
| Material Type | Key Properties | Ideal Applications |
| Acetal Homopolymer | Higher tensile strength, stiffness, and heat resistance | Automotive gears, precision mechanical components |
| Acetal Copolymer | Better impact resistance, chemical resistance, and processability | Medical devices, food-contact parts (FDA-approved grades) |
| Glass-Filled POM | Enhanced rigidity and dimensional stability (up to 30% glass fiber) | Structural parts, industrial equipment components |
| PTFE-Added POM | Lower friction coefficient (ideal for sliding parts) | Bearings, bushings, conveyor components |
Our team provides material selection guidance, helping you choose the best POM variant based on your project’s requirements (e.g., load, temperature, chemical exposure).
Surface Treatment: Enhancing POM Part Performance & Aesthetics
While POM has excellent natural properties, surface treatment can further enhance its performance, durability, or appearance. We offer a range of surface finishing options tailored to POM’s characteristics:
| Surface Treatment | Purpose | Benefits |
| Polishing | Improve surface smoothness | Reduces friction, enhances aesthetics, easier cleaning |
| Coating (e.g., PTFE coating) | Increase chemical resistance | Protects against harsh chemicals, extends part life |
| Painting | Add color or branding | Improves visual appeal, suitable for consumer goods |
| Plating (e.g., nickel plating) | Enhance conductivity or corrosion resistance | Ideal for electronic components requiring electrical contact |
| Texture (e.g., matte or textured finish) | Improve grip or hide surface imperfections | Useful for handles, knobs, or parts with human interaction |
We work with you to determine if surface finishing is necessary, ensuring the treatment aligns with your part’s end-use.
Tolerances: Meeting the Strictest Precision Standards
Precision is non-negotiable in POM CNC Machining—especially for critical applications like aerospace or medical devices. Our processes are optimized to achieve tight tolerances and exceptional dimensional accuracy, adhering to global quality standards. Below is a comparison of our typical tolerances versus industry averages:
| Tolerance Type | Our Typical Capability | Industry Average | Quality Standard Compliance |
