Numerical Simulation Research of Precision Injection Molding Control Method Based on P-V-T Properties of Polymers

Abstract:

Nowadays, with the rapid development of aerospace, auto, communication, consumer electronics and other fields, precision injection molding has been widespread concerned. P-V-T (Pressure-Specific-volume-Temperature) properties are inherent characteristics of polymers. In this paper, P-T parameters were set up in packing stage to achieve constant specific-volume control. Numerical simulation of P-V-T control strategy with Moldflow was carried out. Compared with conventional control strategy, the results showed that P-V-T control of precision injection molding could bring out more uniform density distribution, reduction in volume shrinkage and warpage of molded parts. It was concluded that the P-V-T control method could effectively improve the molding quality of the plastic product.
