The material barrel of the injection machine does indeed have independent temperature sensors and controllers.
Heating coils are usually installed in the material cylinder and other parts of injection machines, which convert electrical energy into thermal energy to heat the plastic raw materials inside the cylinder. In order to ensure that plastic raw materials can be plasticized and molded at a suitable temperature, the material barrel of the injection machine is equipped with an independent temperature sensor. These sensors closely monitor the temperature in different areas of the material barrel and provide real-time feedback to the temperature controller.
The temperature controller is the core component of the injection machine temperature control system. It adjusts the heating power of the heating coil through a certain control algorithm based on the preset temperature setting value and the actual temperature value feedback from the temperature sensor, in order to maintain the stability of the temperature inside the barrel. When the temperature is lower than the set value, the temperature controller will continue to heat the heating coil; When the temperature reaches or exceeds the set value, the temperature controller will adjust the heating power of the heating coil or stop heating according to the control strategy.
In addition, the temperature control system of injection machines usually has intelligent regulation functions, which can automatically adjust the temperature setting value and control strategy according to the actual needs of the production process, to adapt to the requirements of different plastic raw materials and molding processes. At the same time, the system also has data analysis and recording functions, which can record every temperature change and adjustment process in detail, providing valuable data support for subsequent process optimization and quality control.
