Engineering Plastic

Engineering plastic (such as PA, PC, ABS, PET, PPS, PEEK, etc.) is widely used in the fields of electronics, electrical appliances, automobiles, transportation, aerospace manufacturing, national defense, and military industry, etc. Therefore, engineering plastic compounding is a main application of twin screw extruders. Jinwo engineering plastic compounding extruder line can improve the performance of machines and increases the output.
