POM board has high mechanical strength, high rigidity, high hardness, excellent elasticity, sliding and wear resistance, good creep resistance, even at low temperatures, it has high impact strength, very Good dimensional stability and excellent mechanical properties. It is widely used to manufacture various sliding rotating machines, precision parts, gears, bearings, etc.
The combination of the unique physical and chemical properties of thin sheet POM CO allows it to be processed in two main ways:
-Machining the blade tools on the processing equipment.
-Cutting the blank, and then forming in a closed heating mold.
