Plate And Sheet Layer, Muti Layer Extrusion Line

These Plate And Sheet Layer, Muti Layer Extrusion Line consists of KRSJ-series plate &sheet special-purpose single screw extruder KRSJZ-series conical twin screw extruder Or KRSJP-series parallel twin screw extruder; equipped with auxiliary downstream accessories and moulds, the flowering can be produced: PP, PS, HIPS, PE, ABS, EVA, PMMA, PC, PT, PVB, PVC and other plate & 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, The machinery unit has stable performance and efficient operation.
