5. details of pp hollow board extruder/PP board extrusion line
a. Extruder for pp hollow board extruder/PP board extrusion line
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.
The specially designed screw and the advanced controlling system ensure excellent plasticization, high output and stable extruding.
auto spiral screw feeder
drying hopper
siemens motor
aluminum heater
b. Mould for pp hollow board extruder/PP board 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.
c. calibrating table for pp hollow board extruder/PP board 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.
d. haul off device for pp hollow board extruder/PP board 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.
e. Heating oven for pp hollow board extruder/PP board 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
f. corona treatment for pp hollow board extruder/PP board extrusion line
The advanced large area conductive heating mode can effectively remove the stress of plate and further improve planeness of the plate.
g. Auto Cutter for pp hollow board extruder/PP board extrusion line
Accurate instant length-fixed cutting and automatic up-down discharging system combined with alloy steel sharp blade realize high quality of cutting.
6. how to make a box ?
How to make PP packing box from the PP hollow corrugated sheet?
Item | PP packing box making Machine | Note |
01 | Material Mixing machine | For mixing material, such as chemicals, color masterbatch, filling masterbatch, recycle material |
02 | PP hollow corrugated sheet extrusion line | For makeing Pp hollow corrugated sheet for required width and thickness. width: 1200-2700mm thickness: 2-12mm |
03 | PP hollow sheet die cutting machine | For cutting the Pp sheet into required shape for folding box |
04 | PP hollow sheet printing machine | for printing logo and designs on the Packing box, there is different printing machine, such as single color printer, double color printer, four color printer. |
05 | PP hollow sheet welding machine PP hollow sheet bookbinding machine | For folding the Pp hollow sheet into required box shape, welding machine and bookbinding machine both can work for |
7. Comparing of canton packing material and PP hollow sheet material
a, Paper - paper fear of water, fear of tide, perishable, can not guarantee the quality of the product transport, there may be increased costs, so most of the cartons, cartons, cardboard and other paper products can only be used once.
b, PP hollow sheet related products can be flexibly produced, compared to the expensive plastic injection box, PP hollow sheet box cheaper many, customized according to customer size, thickness, toughness, hardness, printing, etc.
c, Traditional cartons will be broken after several times of using, the PP hollow sheet crates life is about 20 times of the carton material, or even longer, it can reduce the using cost greatly.
d, And the PP hollow sheet products are non-toxic, pollution-free, environmental protection, waterproof, moisture-proof, shock absorption and other characteristics, compared with traditional cardboard, wood, easy to use, easy to store, can be reused, long life, but also recycling, Higher social and economic value.
