In the paper production process, Heating Roller plays a vital role and is mainly used in the steps of drying (making the paper evaporate water quickly in a short time) and calendering (avoiding paper surface defects caused by uneven temperature).

The role of Heating Roller in the plastic industry is mainly reflected in: uniform heating (avoiding local overheating or overcooling), improving the surface quality of plastic products, enhancing physical properties, improving production efficiency, and energy saving and environmental protection.
