PP PE PC Plastic Hollow Corrugated Panel Making Extruder Machine Manufacturer

Qingdao Tongsan Plastic Machinery Co.,ltd is a professional plastic extrusion machines manufacturer which has more than 20 years experience.Our company self-developed plastic hollow corrugated sheet extrusion line with the feature of excellent configuration, stable operation, high production efficiency and best-selling at home and abroad.
The plastic hollow sheet is eco-firendly new material in the market. It can be ordered and manufactured by market requirement with different size and form,the container has been used in replacing the paper box and calcium plastic.
The hollow sheet is widely used in machinery,electron,appliance,food,advertising,interior decoration material,glass,agricultural product etc packing and transporting.
With the developing of e-commerce,the container is used largely more and more ,the logistics industry proposes high demand for the packing materials which are easier to use and transport,require simply technology and can be finished in short time.
Our hollow corrugated sheet making machine can produce the sheet with the width of 1220-2450mm and thickness of 1.5mm-12mm.We also can give the auxiliary machines for the plastic hollow sheet slit,printed,weld,bound etc.

Our hollow corrugated sheet making machine can produce the sheet with the width of 1220-2450mm and thickness of 1.5mm-12mm.The details of the production line:

1,Extruder

The specially designed screw and the advanced controlling system ensure excellent plasticization,high output and stable extruding.We have the co-extrusion type to use the recycled plastic to reduce the cost with high quality products.

2,Screen changer

Quick screen changer of hydraulic system ensure the continuously working of screen changing.Double position combined with special sealing structure guarantee stable operation of screen changer.

3,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.

4,Vacuum calibrating table

Heating exchanging and cooling system of quick speed in calibrating system alternate effectively and ordinally with vacuum system,which ensure 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.

5,Tractor

There are two tractor.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.

6,Stress remover

The advanced large area conductive heating mode can effectively remove the stress of plate and further improve planeness of the plate.

7,Corona machiner

In order to improve the surface tension of the hollow sheet surface, and thereby improve the printing ink fastness, the hollow corrugated sheet surface will under corona treatment, so that the surface produces micro-concave dense holes, plastic surface roughening, increase the surface activity.

8,Cutting machine
