Plastic Sheets Extrusion Line Three Rolls Calender Extruder NSK Bearing SIEMENS Drive Motor

Operating Principle

• The calender is usually driven by an electric motor, and the power is transmitted to the drum or pressure plate through the reducer.
• During the working process, the material passes through the gap between the roller or the pressure plate, and the fiber or film layer on its surface is bonded to each other by the action of pressure, forming a smooth and flat surface.
• For paper or plastic film and other materials, the calender through continuous rolling, under the joint action of temperature and pressure, the coating attached to the calender surface is calender, thereby improving the gloss and flatness.

Applicaion

Widely used in printing, packaging, plastic products, metal processing and other industries. After coating on the surface of the printed matter, wait for the glazing layer to dry, if you need to improve the smoothness and gloss of the glazing coating again, you can press the calender. In addition, the calender is also used for sheet metal compression in metal processing, dressing irregular surfaces, making machine parts, etc.

Performance and effect

The gloss of the material treated by the calender can be significantly improved. Generally, the gloss after glazing is about 65-85%, and the gloss after calendering can reach more than 90-95%. At the same time, the calender can also make the surface of the material more flat and smooth, and improve the overall quality of the product.
