POM materials commonly used in plastic mold injection molding

Today is July 27th. Another month in a blink of an eye, the situation of Dongguan Plastic Mould Factory is ups and downs, just as editing my life is also ups and downs. It is still necessary to rely on one's own efforts to slowly improve and get out of the predicament. I believe that the condition of Dongguan Plastic Mould Factory will be better and better, and your life will be better and better. Ok, today I will introduce you to the POM materials commonly used in plastic mold injection molding.


First, let's take a look at the chemical and physical properties of POM. POM is a tough, resilient material that retains excellent creep resistance, geometric stability and impact resistance even at low temperatures. POM has both homopolymer materials and copolymer materials. The homopolymer material has good ductility and fatigue strength, but is not easy to process. The copolymer material has good thermal stability, chemical stability and is easy to process. Whether a homopolymer material or a copolymer material, it is a crystalline material and does not easily absorb moisture.


The high degree of crystallization of POM results in a relatively high shrinkage rate of up to 2% to 3.5%. There are different shrinkage rates for a variety of different reinforced materials.


POM has a very low coefficient of friction and good geometric stability, making it ideal for gears and bearings. Because it also has high temperature resistance, it is also used in pipeline devices (pipe valves, pump housings), lawn equipment, etc.
