Interpretation for the Pressure and Temperature Signals of Injection Molding Process

Yugang Huang, Suhua Zhao

Abstract


An apparatus was developed to acquire temperature and pressure data from the injection molding process. There were three collecting points along the flow path which were allocated at the entrance to the nozzle, near the cavity gate and at the cavity end. Values and plots of temperature and pressure signals were interpreted. Firstly, each acquired signal was detailed introduced, and the characteristic points and segments of the signal plot were explained. Furthermore, comparison of process information which was introduced by one single was made among all of the acquired signals. The practical analysis shows that the pressure signal near the cavity gate is the most effective to describe the status of the sample melt during the injection molding process. But it has the significant delay of indicating the beginning of the cavity filling. With the explanation of signals, the injection molding experiments on the self-developed apparatus can be used to study the processing parameters of sample material.
