Abstract: Polymer materials such as rubber and plastic exhibit poor thermal conductivity and significant viscous dissipation, leading to a significant rise in temperature during the extrusion molding process. Excessive temperatures may increase the thermal history of polymers, cause chain scission due to high-temperature oxidation, damage their original properties, and increase energy consumption, thereby affecting the molding quality of polymer products. Based on these issues, this article analyzed the causes of temperature rise during the polymer extrusion process, reviewed the contributions made by domestic and foreign scholars in the direction of low-temperature extrusion technology from the aspects of barrel cooling devices, temperature control systems, screw structure optimization, and measures taken in energy consumption management. Finally l the future development trend of low-temperature extrusion technology was prospected.

Key words: low-temperature extrusion, screw structure, cooling device, temperature control, energy consumption management
