Introduction:

This unit is a specialized equipment for extruding LDPE/PP/PC hollow grid boards. Its products have a smooth, beautiful surface, and are resistant to pressure, and are widely used in many fields such as construction, packaging, and decoration.

This production line is used for the continuous production of PVC, PE, PP hollow grid boards, which are widely used in building decoration, advertising layout, highway noise, sound insulation, and packaging.

PE and PP hollow grid boards can replace cardboard boxes as packaging boxes, with light weight, high strength, moisture resistance, and corrosion resistance. Finished board width 1220-2100mm, thickness 2-12mm

1. Extruder: The special design of the screw and advanced temperature control system ensure good plasticization of the plastic and stable extrusion with high output.

2. Screen changer: Choose a hydraulic quick screen changer to make the screen changing process fast and effective; Dual station and special sealing structure ensure stable operation of the screen changer.

3. Mold: The mold is made of high-quality alloy steel and has a highly active throttling device to ensure that the material flow is evenly distributed in the mouth mold and the pressure is consistent; The differential adjustment of the upper and lower mouth molds ensures uniform thickness of the upper and lower walls.

4. Tractor: There are first and second groups of tractors. The first group of tractors is high-power, with a large reduction ratio and multiple rollers. It has excellent low-speed operation performance, high traction force, and can synchronously and evenly pull the sheet out of the vacuum forming table. The second group of tractors undergoes stress relief treatment. Equipped with a trimming device to ensure the effective width and edge quality of the board.

5. Cutting machine: equipped with precise instant fixed length cutting and automatic lifting unloading device, special alloy wear-resistant blade edge, ensuring the quality of the cut surface of the sheet metal.
