Plastic Rapid Prototype POM Plastic Part

CNC Plastic Rapid Prototype POM Plastic Part

I. POM Description

Good mechanical properties and rigidity, and close to the metal material. It’s an ideal replacement material of copper, cast zinc, steel, aluminum and other metal materials. Excellent fatigue resistance and creep resistance. Good abrasion resistance, self-lubricated and friction. High thermal stability, good chemical stability and excellent electrical insulation. And it can be used in temperatures ranging from -50°C to +110°C.

II. POM Characteristics

Advantages: 

♦ High surface hardness, low abrasion consumption, impact fatigue and shock resistance, low coefficient friction, and self-lubricating, therefore, it is the first material choice for manufacturing gear.

♦ High mechanical strength and rigidity. Although the contraction rate is high, the dimension is stable.

♦ Good dielectric properties, solvent resistance, non-stress cracking, no porosity.

♦ Torsional resistance, it can be restored to the original shape when removing the external force.

♦ Low water absorption

Disadvantages: 

♦ Poor acid resistance

♦ Weatherability is not excellent especially the UV

♦ Difficult to glue and paint

III. POM Applications

♦ Machinery industry used to produce gears, springs, axle sleeve, bearings, wheels, connecting rod, impeller blades etc..

♦ Automobile industry

♦ Electronic and electrical appliances

♦ Others such as toys, windows, water tanks and washing basins
