Structure of Machine:
It consists of SBJZ-series plate &sheet special-purpose single screw extruder SJZ-series conical twin screw extruder Or SJ-series parallel twin screw extruder; Equipped with auxiliary downstream accessories and moulds, it can produce: PP, PS, HIPS, PE, ABS, EVA, PMMA, PC, PT, PVB, PVC and other board & sheet.


The machinery unit consists of extruder, Screen changing device, melt pump, T-die, 3-rollr or multiple-roller calender, cooling device, edge cutter, Haul-off system, plate cutter winder, electrical control system.
Others, The working principle is the 3 states of the hot-plastics at different temperatures: The pushing force of the screw change the physical stat from glass state to high elastic state, then glutinous-and-fluid sate, it comes out from the slim gap of the die, the rest of the procedures are calendar, cooling-shaper, edge-cutter, Haul-off, cutter, winder.

Features of the machinery unit: High grade alloy structural steel ( 38CRMOALA) made material barrel& screw and mould, after nitriding treatment. It gets high hardness, corruption and long service life. Choice T-die the flowing passage is designed for easy flowing of thehout any detaining, and the product thickness is even, For the calender, large conical slot is designed, the cooling quality inside the roller is good, and the temperature synchronization,



PC/PP hollow cross-section plate. PVC transparent soft & hard plat & sheet. PVC foamed plate, PMMA/ABS co-extrusion bathing plate, inside chamber plate of the refrigerator and other multiple-layer composite co-extrusion plate & sheet size: Width: 300MM-700MM thickness0.2MM-45MM: Output rate: 80-1800KG. /H. The machinery unit is the best solution for plate & sheet production.
