Application of computer simulation in the optimization of plastics processing technology

The application of proportional integral derivative (PID) and computer aided engineering (CAE) in the optimization and control of plastic processing technology is reviewed. PID method can be used to adjust and optimize the processing technology by stages, so as to obtain the processing technology with good dynamic and steady-state characteristics, and then improve the quality of plastic products. The CAE method is mainly used in the processing of thin-walled products. Through the scientific selection of materials, the rational design of the structure and the effective optimization of the process, the probability and extent of defects in plastic products can be reduced. In the process of process optimization, the use of computer simulation is a highly efficient, reliable and scientific method due to the huge workload.
