Twin Screw Extruder

BC-45 Twin Screw Extruder

The twin screw extruder is specialized equipment engineered for the high-precision manufacturing of plastic seal strips used in resealable packaging. The system comprises a transmission unit, feeding device, barrel, and synchronized screws. Under the action of the twin screws, the raw material undergoes a continuous process of conveying, compaction, melting, and homogenization. This results in a uniform melt that is extruded through the die head under stable pressure, followed by shaping and cooling to create high-quality zipper profiles.

Features
  • Superior Self-Cleaning Action

    Utilizing a co-rotating twin-screw design, the zipper profile extruder generates high shear speeds in the meshing zone where screw flights move in opposite directions. This effectively scrapes away any material adhering to the screws, ensuring an excellent self-cleaning effect.

  • User-Friendly HMI Touchsreen

    Allowing for easy parameter setting, simple operations and quick die changeover.

  • Versatile Customization

    By simply changing various extrusion dies, the plastic seal strip machine can produce a wide range of zipper profile designs to meet different packaging requirements.
