Three Layer PE Sheet Boards Extrusion Line China Plastic ExtruderStructure of PE Sheet Boards Extrusion Line 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.
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.

Performance characteristics
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,
