Custom CNC milling machined POM plastic gear

Machining Characteristics of POM Plastic：

• Dimensional Stability: POM has excellent dimensional stability, making it ideal for precision machining. It maintains its shape and size over a wide range of temperatures and mechanical stresses.
• Low Friction: POM has a low coefficient of friction, which makes it suitable for components that require smooth, low-friction movement, such as gears, bearings, and sliding elements.
• High Strength and Stiffness: POM exhibits high mechanical strength and stiffness, providing robustness and durability to machined parts.
• Good Wear Resistance: POM is resistant to wear and abrasion, enhancing the lifespan of components subjected to repetitive motion or friction.
• Chemical Resistance: POM is resistant to many solvents, oils, and chemicals, making it suitable for applications in chemically harsh environments.
• Easy to Machine: POM is relatively easy to machine compared to many other plastics. It can be cut, drilled, and milled with standard machining tools while maintaining high accuracy and finish quality.
• Thermal Stability: POM can withstand a moderate range of temperatures, making it suitable for use in environments where temperature fluctuations occur.
• Excellent Surface Finish: Machined POM parts typically have a smooth surface finish, reducing the need for additional finishing processes.
• Low Water Absorption: POM has low water absorption, which helps maintain its mechanical properties and dimensional stability in humid or wet conditions.
• Applications: Due to these characteristics, machined POM parts are widely used in automotive, electronic, medical, and industrial applications, including precision gears, bushings, housings, and components that require high precision and durability.
