Injection molding is the most effective process to produce plastic parts of complex shape to the highest precision at the lowest cost. Considerable progress has been made over the last two decades in modeling and simulation of the molding dynamics. However, due to complex material properties and other uncontrollable disturbances, consistency of part quality cannot be assured in production. This...

the variations in plastic injection molding process may lead to the inconsistency of molded parts' dimensions. furthermore, due to the speed of production as well as post-shrinkage of molded parts make the control of process difficult and give inaccurate molded parts. the objective of this research is to predict the dimensions of injection molded parts on the basis of cavity pressure durin...
