Our state-of-the-art Plastic Sheet Extrusion Line is engineered for high-capacity, reliable production of diverse plastic sheets and films. Available in three optimized system sizes (65mm, 90mm, and 120mm extruders), our lines cater to a wide range of output requirements. Built for efficiency and stability, these systems are ideal for manufacturing quality plastic sheets for various industrial applications.

Working Principle:

The plastic material transitions through glassy, elastic, and viscous fluid states within the extruder barrel under controlled temperature and screw rotation. The molten plastic is then uniformly extruded through the T-die. Subsequently, the sheet undergoes calendering for shaping and thickness control, cooling for solidification, edge trimming, haul-off for continuous movement, and finally cutting or winding into the desired form.

Key Features:

• High-Efficiency Single Screw Extruder:

  • Equipped with a robust motor and precise digital control system for consistent operation.
  • Features vacuum venting to remove volatiles, ensuring superior material quality.
  • Includes a quick and easy screen changer for reduced downtime.
  • High-torque gearbox for reliable and efficient power transmission.
  • Flexible lip die for precise control over sheet thickness and width.
  • Optional PLC/PCC control system for enhanced automation and process management.
  • Custom-designed screws available for optimal processing of HIPS, PP, and PET.

• Precision Three-Roller Calender:

  • Three hard surface polished rollers with flawless mirror chrome plating for exceptional surface finish.
  • Engineered for maximum heat transfer efficiency, ensuring uniform sheet quality.
  • Each roller features an independent, high-volume pressurized water temperature control system for accurate thermal management and consistent product dimensions.

• Advanced Cooling System:

  • Utilizes forced water cooling for rapid and efficient solidification of the sheet.
  • Temperature synchronization ensures consistent product quality and dimensional stability.
