It is a high-tech production line especially for the production of rubber sheet with less air bubbles in thin thickness. It consists of a cooling, winding system, pin extruder machine and 2-roll calendar machine. It is suitable for making high-quality rubber sheet, printing sheet, rubber lining sheet. This part is to feed the material to the calendar smoothly, it mainly consists of three parts. The middle part is tightly connected to the extruder, the opening and closing of the upper and lower parts of the extruder are driven by the hydraulic cylinder. The extruder head is made of high-quality steel with smooth working surface. The extruder head contains a set of molds that can change the output sheet width. The molds under the desired sheet width are designed for extruder head hydraulic locking, the maximum pressure is 300 bar. There is a pressure sensor inside the extruder head, the extruder head safety (alarm) system can be adjusted within 260 bar.
