Prediction of Plastic Injection Shrinkage Ratio Using Grey Theory

Abstract:

The simulation method of the article is based on the analysis of injection molding software MPI and grey system simulation method. The basic model of injection molding parameters are mold temperature, melt temperature and dwell time. So it gets technological parameter of volumetric shrinkage ratio with having been selected point. It comes to the value of simulation with using grey system GM (1, 1) and comparing the value with the measure value. It shows that the volume shrinkage rate which is obtained by using MPI simulation and by using GM (1, 1) grey prediction is consistent and the errors are within 2.2% after comparison. The conclusion is that using grey system GM (1, 1) can effectively predict the volume of injection plastic shrinkage rate and its change trend.
