Product Description
CNC milled POM plastic parts are essential components used in the manufacturing and processing of various products. POM (Polyoxymethylene) is a thermoplastic material that is known for its excellent strength, durability, and resistance to abrasion, chemicals, and wear and tear. The CNC (Computer Numerical Control) machining process is used to manufacture these parts, ensuring precision and accuracy in their design and dimensions.
One of the key benefits is their versatility. For example, POM gears are commonly used in automotive transmission systems due to their low friction and excellent wear properties, while POM bearings are used in medical equipment due to their biocompatibility and resistance to sterilization.
In addition to their mechanical properties, they also offer excellent electrical and thermal insulation. They are non-conductive, making them ideal for use in electrical applications, and they have a low coefficient of thermal expansion, which means they can maintain their shape and size even at high temperatures.

Product Feature
POM, also known as polyoxymethylene, is an engineering thermoplastic that is widely used in industrial applications due to its unique physical properties. Here are some of the most notable features of this material:
1. High tensile strength:
POM exhibits a tensile strength of around 70 MPa, which is higher than many other thermoplastics. This makes it suitable for high-stress applications.
2. Good wear resistance:
Due to its highly crystalline structure, POM has excellent abrasion resistance. It can withstand repeated friction and wear without losing its dimensional stability.
3. Low friction coefficient:
POM has a low coefficient of friction, which means that it can slide easily against other materials without causing excessive wear or heat buildup.
4. High stiffness:
POM has a stiffness of around 2,500 MPa, which makes it suitable for applications that require tight tolerances and precise geometries.
5. Good chemical resistance:
POM is resistant to many common chemicals, including acids, alcohols, and oils. This makes it ideal for use in harsh environments.
Despite its many advantages, POM also has some drawbacks that need to be considered:
1. Poor UV stability:
POM is prone to degradation when exposed to UV light, which can cause it to become brittle and crack.
2. Limited temperature range:
POM has a relatively low melting point and can only withstand temperatures up to around 170°C. This means that it may not be suitable for some high-temperature applications.
3. High water absorption:
POM has a relatively high degree of water absorption, which can affect its mechanical properties over time.

Application
1. Consumer Goods Industry:
CNC milled POM plastic parts are widely used in consumer goods such as sporting goods, toys, and home appliances. For example, POM gears are commonly used in sports equipment such as ski bindings and ice skates due to their high strength and wear resistance. POM also finds applications in toys, especially those that need to withstand impact. It is also used in various components of home appliances, such as blenders, mixers, and door handles due to its durability and smooth surface finish.
2. Packaging Industry:
POM is an excellent material for packaging applications due to its high stiffness and low moisture absorption. It is commonly used in the manufacturing of bottle caps, closures, and pumps for cosmetics and personal care products. POM’s low friction coefficient and excellent dimensional stability also make it a good option for packaging machinery components such as gears, bearings, and rollers.
3. Textile Industry:
The textile industry also uses them in various applications. For example, POM bobbins and gears are commonly used in textile machinery due to their wear resistance and low friction properties. They also play a significant role in the smooth operation of weaving machines.
4. Construction Industry:
POM finds its application in various components used in construction equipment. For example, POM bushes and gears are used in cranes, excavators, and bulldozers due to their ability to withstand high loads and harsh environments. POM also plays an important role in the manufacturing of sliding doors, windows, and locks.
5. Food Industry:
The food industry uses them extensively due to its excellent resistance to chemicals and high temperatures. POM’s non-toxic and odorless properties make it an ideal material for food contact applications such as conveyor belts, pump components, and food processing equipment.
6. Agricultural Industry:
CNC milled POM plastic parts also find extensive use in the agricultural industry due to their high durability and corrosion resistance. For example, POM bearings and gears are used in various agricultural machinery such as tractors, harvesters, and seeders.
