And because POM plastic materials are not easy to absorb moisture and have good dimensional stability in a humid environment, it is mainly used in gears, bearings, auto parts, machine tools, instrument internals and other products with a skeletal operating environment that operate in a humid environment .

　　Due to the different performance attributes, the process characteristics of POM and other plastic materials are also quite different. Here we explain the process characteristics of POM plastic materials:

　　POM plastic raw materials can be dried without processing, it is best to preheat during processing, which is beneficial to the stability of product size; because the processing temperature of POM is very narrow, the residence time in the barrel is slightly longer or the temperature exceeds a certain temperature It will decompose in time and produce strong irritating formaldehyde gas, so pay attention when processing.

　　POM products have a large shrinkage rate, which is easy to shrink or deform. The POM has a large specific heat and a high mold temperature. The product is very hot when it is demolded. It is necessary to prevent scalding of the fingers. "Material temperature, higher mold temperature" under the conditions of molding processing, precision molds need to be used to control the mold temperature.

The success of the POM plastic raw material injection process is the most critical for its products. Without knowing the process characteristics of the plastic raw materials, it is impossible to grasp the production process and details of the POM plastic raw material products. In this case, it will waste production resources and increase production costs. POM, as China's five general-purpose engineering plastics, has become more and more widely used, and its market potential is unlimited.
