In recent years, the modern plastic injection molding process has been inseparable from sensors, and both the injection molding machine and the mold required for injection molding require sensors. These electronic “perceived organs” undertake the process monitoring and quality inspection tasks of various cavities in modern production. With the development of digitalization and networking, sensor technology is preparing to expand its application range in the next stage, making it the main promoter of the development of Industry 4.0.

The sensor in the mold can be combined to measure the pressure and temperature in the mold. Dr. Thomas Walther, head of the application technology department at the Arburg injection molding machine manufacturing company, said: "The use of sensors is ultimately to visualize the state of the cavity." This means that the processor can know the current operating conditions in the "black box" through the sensor. Machine operators can access information directly from the mold sensor.

By using a sensor in an injection mold, not only the cavity pressure can be measured, but also the temperature and flow rate of the temperature controller during feed and reflow. Martin Schramm from Burkert Fluid Control Systems, Inc. states: "The better the temperature control process, the higher the quality of the product." Sensors play an important role in the use of injection molding tools in Industry 4.0. A control system consisting of sensors optimizes the regulator and valve network by integrating I/O links.
