Abstract：Through pressure sensors and temperature sensors which are installed in multiple places in the cavity, a digital monitoring system in molding process of automobile injection molding products was constructed. This system can timely capture the real data and changes of important parameters such as cavity pressure and temperature in the molding process. And in this way, the required molding process replication can be done easily and quickly when the mould transfer between equipment or at different plants is needed. Furthermore, automatic identification and selection of defective products can also become reality. According to the sensor signals, a new sequential injection molding process can be achieved, which can make engineers get rid of the phenomenon that engineers just have to rely on the indirect parameters displayed by the equipment screen and get rid of the state of over reliance on engineer's experience. Thereby, the technology enables digital monitoring of injection molding process to become true.
