A system includes a cavity, an injection nozzle configured to inject material into the cavity, and a plurality of sensors at sensor locations. Each of the plurality of sensors is configured to measureparameters at one of the sensor locations. The system lacks a strain gauge. The system further includes a controller configured to control a flow rate of the injection of material into the cavity. The controller is configured to receive the measured parameters and compare the received information to predetermined curves. The controller is configured to control the flow rate when the measured parameters deviate from the predetermined curves. 一种系统包括空腔、被配置为将材料注射到所述空腔中的注射喷嘴，和在传感器位置处的多个传感器。所述多个传感器中的每一个被配置为在所述传感器位置中的一个处测量参数。所述系统没有应变计。所述系统进一步包括控制器，所述控制器被配置为控制材料注射到所述空腔中的流量。所述控制器被配置为接收所测量的参数并将所述接收的信息与预定曲线进行比较。所述控制器被配置为当所述测量的参数偏离所述预定曲线时控制所述流量。
