Industrial Packaging PP PE PC Plastic Hollow Sheet/Plate/Board Making Extruder Machine price

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.

Our advantage of Our PP hollow grid sheet

1,We adopt fan cooling style, the cooling speed can be fast.So it won’t shrink after cutting, it can effectively reduce the error.And the speed of production can be more fast.

2,The oven’s material is 201# stain steel,there are total 4 meters with two 2 meter oven.The customer can choose to use one or two according the product need.

3,Our company is the only one who adopt imported rubber roller which softness  is more suitable for hollow grid sheet.The friction force of the rubber roller is more strong ,more durable and longer lasting.

4,The cutter adopt SERVO motor from Japan

5,The haul off machine adopt helical gear

6,The mold adopt special steel which made with Italian formula technology ,it has the characteristics of memory rebound.The mold is more wear-resistant and the service life is several times longer than ordinary mold.

7,One set mold can produce different thickness range ,such as 2mm-5mm,5mm-8mm,8mm-12mm,just by change the center of the mold.

8,The screen changer adopt silk screen circulation, altogether 4 pcs  silk screen, 3 normal use, 1 standby . It does not need to stop when changing the silk screen .

9, The production line adopting the co-extrusion mode,so the recycled material (80 %-90 %) can be used in the middle, and new material can be used for the surface. The product has smooth surface which no visible difference to the naked eye, so it can reduce a lot of costs.

10,Our equipment has a good look. The wire is convenient to connect and the plug is easy to identify with the mark number.

11,There are 6 rollers on the front haul off machine and 3 rollers on the second haul off machine ,so the production line is more stable.

12,The haul off machine and the calibrating platform are on the same guide rail for convenient synchronous alignment adjustment.
