PP Coroplast Hollow Corrugated Sheet Making Machine by Qingdao Tongsanhegu Plastic Machinery Manufacturing Co., Ltd.
PP hollow sheet making machine /plastic hollow board extrusion line
This PP hollow corrugated sheet making machine 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 corrugated sheet extrusion line
The specially designed screw and the advanced controlling
system ensure excellent plasticization, high output and stable extruding.

4, aluminum heater
Mould for PP hollow corrugated sheet extrusion line
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.
calibrating table for PP hollow corrugated sheet extrusion line
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
haul off device for PP Hollow corrugated sheet extrusion line
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.
Heating oven for PP Hollow corrugated sheet extrusion line
the heating oven device is necessary for the PP hollow sheet to remove the stress of the sheet,
the heating oven should be made by 304 stainless steel,
the heating oven is equipped with separately temperature control system for each zone to
ensure the heating to be uniform, 4 meter lengths of heating oven is necessary,
corona treatment for PP Hollow corrugated sheet extrusion line
The advanced large area conductive heating mode can effectively remove the stress
of plate and further improve planeness of the plate.
Auto Cutter for PP Hollow corrugated sheet extrusion line
Accurate instant length-fixed cutting and automatic up-down discharging system
combined with alloy steel sharp blade realize high quality of cutting.
