Best POM CNC Machining Services
MachMaster offers precision CNC machining for POM parts, known for their high stiffness, low friction, and excellent wear resistance. POM (Acetal) is ideal for producing durable, high-performance components for automotive, industrial, and consumer applications.
Material Description
Polyoxymethylene (POM), also known as acetal, is a high-performance thermoplastic with superior dimensional stability, low moisture absorption, and excellent chemical resistance. POM is widely used for manufacturing precision components that require strength, low friction, and long-term durability.
Key Advantages of POM
- Excellent stiffness and tensile strength
- High wear resistance and low friction
- Good chemical resistance, even in harsh environments
- Stable mechanical properties over a wide temperature range
- Minimal moisture absorption, maintaining shape and performance
Wide Application of POM
POM is used in a variety of applications that require low friction, high strength, and excellent wear resistance. Typical uses include:
Automotive parts (e.g., gears, bushings)
Industrial components (e.g., bearings, conveyor systems)
Electrical housings and enclosures
Consumer goods (e.g., handles, fasteners)
Medical devices (e.g., valve components, implants)
POM Grades We Machine
We machine various grades of POM based on the application requirements:
POM-C (Copolymer) – Offers superior strength and chemical resistance, ideal for mechanical components like gears, bearings, and precision parts.
POM-H (Homopolymer) – Higher stiffness and rigidity compared to POM-C. Used for parts requiring exceptional wear resistance, such as in automotive applications.
FDA-Compliant POM – Biocompatible grade suitable for medical and food-grade applications.

POM Grades We Machine
POM (Polyoxymethylene) is available in different grades tailored for various industrial needs. We work with the most common types of POM, each offering unique advantages for different applications. Below is an overview of the commonly machined grades:
| Material | Description |
|---|---|
| POM-C (Copolymer) | POM-C, also known as acetal copolymer, is a versatile thermoplastic with excellent machinability, low friction, and high dimensional stability. It’s ideal for producing durable, precision components that don’t absorb water easily. |
| POM-C FDA Approved | This grade of acetal copolymer is FDA-approved, ensuring compliance for use in medical and food-grade applications. It offers superior rigidity, shape retention, and excellent mechanical properties, making it a great choice for high-performance parts. |
| POM-H (Homopolymer) | POM-H, or acetal homopolymer, is a highly rigid, low-friction material known for its high strength and low moisture absorption. It is ideal for applications that require excellent stiffness and wear resistance in harsh environments. |
| POM-C ESD (Electrostatic Discharge) | This special grade of POM-C features anti-static properties, making it perfect for use in sensitive electronic environments, such as clean rooms and safety zones, where electrostatic discharge could cause issues. |
POM Properties Overview
| Material | CNC Process | Tensile Strength | Elongation | Hardness (Rockwell) |
|---|---|---|---|---|
| POM-C (Copolymer) | Milling | 8,000 psi | 30% | R120 |
| POM-H (Homopolymer) | Turning | 9,500 psi | 25% | R130 |
