Plastic PP Packing Box Grid Sheet Hollow Board Making Machine
This production line is used for PP PC hollow grid board, this board is widely used in construction, decoration, packing, advertise.
Extruder:
The specially designed screw and the advanced controlling system ensure excellent plasticization, high output and stable extruding.
Screen changer:
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.
Mould:
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.
Vacuum calibrating stable:
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:
There are two tractors. The first one is of high powr, 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:
The advanced large area conductive heating mode can effectively remove the stress of plate and further improve planeness of the plate.
Cutting machine:
Accurate instant length-fixed cutting and automatic up-down discharging system combined with alloy steel sharp blade realize high quality of cutting

Hollow grid pp sheet making machine can be used to produce PC, PP, PE hollowness grid boards.
The board is popularly used to buildings, decoration, advertisement ornament, sound insulation on road and packaging.
The PP hollowness board can replace the paper packaging canton with the advantages of light weight, high strength, damp-proofing and corrosion-resistance.
