Adopts a high-efficiency PE/PP single-screw extruder. The extrusion section is equipped with a forced water-cooled feeding zone, which significantly reduces the power consumption of the main drive motor. The extruder features a large length-to-diameter (L/D) ratio screw, providing strong material adaptability and excellent plasticizing performance.
Features a coat-hanger type flow channel design with nitrided and polished surfaces. The specially designed thickness adjustment system ensures easy operation and high precision control.
Depending on the product width, the calender can be configured in vertical or inclined structures. The specially designed internal flow channel of the rollers ensures precise temperature control, guaranteeing excellent surface gloss for geomembranes and waterproof sheets. The high-precision mirror rollers are hard-chrome plated for superior strength and long service life.
Supports and cools the freshly extruded heat shrinkable tape, ensuring flatness and uniform thickness.
Monitors and adjusts the operational parameters of the production line in real time to ensure stable, safe, and efficient production.
