PP/PE/ABS Thick Board Extrusion Line

Designed for PP, PE, ABS and modified compounds, this line integrates extrusion, calendering, cooling, cutting and stacking to produce 3–30 mm engineering boards for automotive and industrial applicat

Product Advantages

  • A high-torque screw with a large length-to-diameter ratio is optimized according to the material properties, improving melt uniformity and reducing bubbles, delamination and cracking in thick boards.
  • Three-roll calendering, staged cooling and controlled slow cooling gradually release internal stress, improving board flatness and dimensional stability while reducing warpage.
  • Online length measurement, cut-to-length and automatic stacking reduce manual handling and improve production continuity.
  • Key components, including the screw, barrel and die, are manufactured from wear-resistant alloy materials for continuous operation, extended service life and lower maintenance costs.
  • A single-screw or twin-screw extruder can be configured according to the material and product requirements, with support for qualified recycled materials.

Product Details

  • The PP/PE/ABS thick board extrusion line mainly consists of a material handling and feeding system, a high-torque single-screw or twin-screw extruder, a hydraulic screen changer, a coat-hanger T-die, a three-roll calendering and cooling unit, haul-off equipment, online length measurement, a cut-to-length unit, an automatic stacking system, and a PLC control system.
  • The screw geometry, die flow channels, roll temperatures, haul-off speed, and cooling and forming process are coordinated for the melt-strength, cooling-efficiency and internal-stress requirements of 3–30 mm thick boards.
  • Staged cooling and controlled slow cooling allow internal stress to be released gradually, helping reduce bubbles, delamination, deformation and warpage caused by uneven cooling. The online cutting and stacking system completes board measurement, cutting, conveying and collection according to the preset length.
  • Depending on the configuration, the line can process PP, PE, ABS, modified compounds and qualified recycled materials. Board thickness, effective width, output capacity, surface finish and downstream configuration can be customized.
