PP corrugated hollow sheet extrusion machine

PP PE PC Twin wall sheet production line

Description of PP corrugated hollow sheet extrusion machine

This production line realizes continuous production of PC/PE/PP hollow grid plate, which is applicable to construction decoration, advertisement collocation, and noise insulation of highway as well as packaging. PE/PP hollow grid plate is an ideal substitute for paper box in making packaging box. It is characterized by light weight, high intensity, dampproof, and anticorrosion. The width of the products is 1220-2100mm, and the thickness is 2mm-12mm.

Extruder for pp hollow sheet machine: The specially designed screw and the advanced controlling system ensure excellent plasticization, high output and stable extruding.

Co-extruder for the PP hollow sheet machine. the co-extrusion system is used for making AB layer PP hollow sheet.

the inner layer can use recycled PP material or High PP filling material.

Mould for pp hollow sheet machine: Mould adopts high-quality alloy steel and throttling device to ensure even pressure of feed influent at the mould lips, and also differential action of up-down piece guarantee even thickness of the plate.

Screen changer for pp hollow sheet machine : Quick screen changer of hydraulic system ensures the short course of screen changing. Double-position combined with special sealing structure guarantee stable operation of screen changer.

Vacuum calibrating table for PP hollow sheet machine: Heating exchanging and cooling system of quick speed in calibrating system alternate effectively and ordinally with vacuum system, which ensures calibrating precision. Vacuum system composes two independent subsystems and each is equipped with several fixed circulating vacuum lines of three-point type. Meanwhile, each line carries vacuum regulating system and vacuum display system that realize even and stable vacuum degree of plate surface.

Tractor for PP hollow sheet machine: There are two tractors. The first one is high power, high reduction ratio, multi-roller type, well low-speed operation, high traction and is able to draw the plate up from the calibrating table evenly and synchronal. The second one is designed to remove stress, and in addition it is equipped with edge-cutting device to ensure the valid width and smooth cut of the edges.

Stress remover corona treatment device for PP hollow sheet machine:The advanced large area conductive heating mode can effectively remove the stress of plate and further improve planeness of the plate.

Auto Cutting machine for PP hollow sheet machine: Accurate instant length-fixed cutting and automatic up-down discharging system combined with alloy steel sharp blade realize high quality of cutting.
