POM plastic raw materials commonly known as "Saigang" market application potential unlimited
POM plastic raw material is a crystalline plastic, which is very good in steel, so it is commonly known as “Saigang”. It has various excellent properties such as fatigue resistance, creep resistance, wear resistance, heat resistance and impact resistance, and has small friction coefficient and good self-lubricating property. The unmodified POM plastic material is a white or black plastic granule with high hardness, high rigidity and high wear resistance.
Because POM plastic raw 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 that play a skeleton role in the damp environment. .
Because of its different performance attributes, the process characteristics of POM and other plastic materials are quite different. Here we will explain the process characteristics of POM plastic materials:
POM plastic raw materials can be used without pre-heating before processing. It is best to preheat during processing. This is good for the dimensional stability of the product. 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 and produce irritating formaldehyde gas, so be careful when processing.
POM products have large shrinkage, easy to shrink or deform, POM is hotter than heat, mold temperature is high, the product is hot when demoulding, and it is necessary to prevent burns on the fingers. Finally, it should be pointed out that POM should be at medium, medium and low temperatures. The molding process is carried out under the conditions of material temperature and high mold temperature, and the mold temperature is controlled during the molding of precision products.
The success of POM plastic raw material injection molding 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 POM plastic raw materials. In this case, production resources will be wasted and production costs will be increased. As the five general engineering plastics in China, POM has become more and more widely used, and its market potential is unlimited.
