Operating Principle

Pressure and temperature are applied to the material through the roller to achieve the effect of flattening and calendering. Specifically, the calender is usually driven by an electric motor, which transmits power to the roller or pressure plate through the reducer. During the working process, the material is subjected to the combined action of pressure and temperature through the gap between the rollers or pressure plates.

Under the action of pressure, the fiber or film layers on the surface of the material are bonded to each other to form a smooth, flat surface. At the same time, some calendering machines also make the surface of the material reach a certain temperature by heating, thereby increasing the plasticity and fluidity of the material, which is conducive to the formation of a smoother surface.
