Plastic Hollow Sheet Making Extruder Machine for layer pads boxes tray advertising printing sheet

Qingdao Tongsan Plastic Machinery co.,;td have been develop the PP hollow corrugated sheet making machine since 2015,now we have the machines for the PP hollow grid plate  width from 1220mm to 2450mm and thickness from 1.5mm to 12mm.We have different model production line,such as the 1400 type PP hollow sheet extruder machine,1860 type PP corrugated sheet production line,2300 type PP hollow corrugated board making machine,2600type plastic hollow grid panel making machine,and for each model,we have the co0extrusion type for customer choose.The co-extruder type can use 20%-60% fillermatch for reduce the cost,so our customer can product the cost competitiveness sheet with goog quality.Our machine have the advantage of high output,easy operation,high precision,good products with smooth surface straight rib.

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

Accurate instant length-fixed cutting and automatic up-down discharging system combined with alloy steel sharp blade realize high quality of cutting.
