Advantages of pp corrugated sheet extrusion line

New design screw extruder: line with market demands and adapt to many kinds of raw materials, with the advantages of good plasticizing, uniform distribution and high output.

Hydraulic pressure screen exchange: short course of changing screen and stable operation of operators

Molding die: with high quality alloy steel lips and restrict bars to ensure even pressure and uniform thickness of the finished sheet.

Vacuum Calibrator: convective heat with array interleaved to ensure high precise calibration. the vacuum system composes two independent subsystem, equipped with several closed loop vacuum lines, which carries vacuum regulating system and vacuum displaying system, to ensure stable and even vacuum degree of sheet surface.

Haul off Device:

First haul off device is of high power, high reduction gear ratio, multi roll type, high traction, to draw the sheet up from calibrator evenly and synchronizedly.

Second haul off device is to remove stress and equipped with edge cutting device to ensure effective width and smooth cutting.

Cutting Machine: Accurate imported automatic length indicator, adopts electric fly cutting and traversing cutting.

Electrical control system: adopt PLC to control precise parameters.
