This kind of line is suitable to producePE/PP/PS/HIPS/ABS/PVC
single-layer and multi-layer sheet with thickness of 0.1mm to 30mm and width of up to3000mm.
T-Die
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.
Three-Roller or Multi-Roller Calender
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.
Double-station hydraulic screen changer
It adopts a dual-channel and dual-station design, and the die head
is equipped with two sets of filtration systems. During normal
production, the two networks operate in parallel to share the load.
When replacing, switch to single network operation through
hydraulic means, and the other network can be replaced without
stopping the machine.
Feature: Change the screen without stopping the machine. It has
excellent sealing performance, a large filtration area, and can
fully remove the gas in the material
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.
Application of ABS, HIPS refrigerator board:This board is suitable to be used in gallbladder in the
refrigerator, door gallbladder, the drawer, water containedplate,
etc.
Application of PE, Pp board:Density low, good sanitation performance, erosion resistance and
heat resistance etc. So, they are widely usedin chemical industry,
erosion resistance project, depuration treatment environment
protection etc. industry
