AI Technical Summary

Problems solved by technology

The current rotational molding equipment is not equipped with a real-time temperature monitoring device, so it is difficult to control the temperature inside the oven, the temperature of the inner and outer walls of the mold and the temperature change of the material during the rotational molding process

Due to the inability to accurately monitor and adjust the temperature parameters in the rotational molding process, the efficiency of rotational molding is low, the energy consumption is large, the quality precision of the processed products is not high, and the selection and application of rotational molding raw materials is limited. The application field of the technology is limited
