High Quality PP Cartonplast Sheet Making Machine / Plastic PP Polypropylene Correx Sheet Machine

PP cartonplast sheet making  machine can used to produce PP hollow sheet, PP corrugated sheet, PP corflute sheet. 

These sheets are widely used in packaging, box making ,printing, and many kinds field

The width of the PP hollow sheet is 1220-2800mm, and the thickness is 2mm-12mm.

The specially designed screw and the advanced controlling system ensure excellent plasticization, high output and stable extruding.

We use four plate circulation screen changer, can achieve no stop screen chaning, it will save mateiral cost and improvie production stablitity.

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.

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.

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.

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

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