1. The main parts such as screw, rod barrel, die head are made of 38CRMOALA alloy steel material and have been nitrided, which has the advantages of wear and corrosion.
2. This machine adopts three-screw mutual aid, which can realize the function of three to five layers of mutual aid. The manufacturing cost of the sheet can be greatly reduced, and the return material and the filler can be added to the main machine in proportion, without changing the shape and forming effect of the sheet.
3. The heating method in the die head, the screen changer adopts a hydraulic double-station device, the screen can be changed without stopping the machine, which is convenient for operation and improves production efficiency. The plastic sheet unit is basically designed and manufactured by our company in absorbing advanced technology at home and abroad. This machine is suitable for producing polypropylene (PP), polyethylene (PE), polystyrene (PS) and other plastic sheets.
