High-Capacity, Fully Automatic 8000mm Geomembrane Extrusion Sheet Making Machine

Key Features & Advantages

Extra-Wide Output: The flagship feature is its ability to produce seamless geomembrane sheets up to 8000mm (8 meters) in width. This significantly reduces installation time and seam counts on-site, enhancing the overall integrity and leak resistance of the final liner system.

High Production Capacity: Built for efficiency, this line ensures stable, continuous output, maximizing productivity and meeting the demands of major projects.

Superior Material Compatibility: The system is compatible with a wide range of thermoplastic polymers, including:

HDPE (High-Density Polyethylene)

LDPE (Low-Density Polyethylene)

LLDPE (Linear Low-Density Polyethylene)

EVA (Ethylene-Vinyl Acetate)

PVC (Polyvinyl Chloride)

Precision Thickness Control: Advanced computer-controlled systems allow for precise adjustment and consistent maintenance of sheet thickness across the entire 8-meter width, ensuring product uniformity and compliance with international standards (e.g., GRI-GM13).

Robust Construction & Stability: The machine frame and components are manufactured with heavy-duty materials to handle the high torque and stresses of wide-sheet production, guaranteeing long-term operational stability and minimal vibration.

Core Components of the Production Line

The complete system is a fully integrated line consisting of:

Automatic Feeding & Mixing System: Ensures a consistent and homogenous blend of raw polymer resin and additives (e.g., carbon black, antioxidants).

High-Output Extruder: A large-diameter, energy-efficient single or twin-screw extruder with precise temperature control zones for optimal plasticizing and melting of the material.

Specially Designed Wide-Slot Die Head: A critical component engineered for a uniform melt flow distribution across the 8000mm width.

Vertical & Horizontal Thickness Gauge: A non-contact, scanning measurement system that continuously monitors and provides feedback for real-time thickness control.

Multi-Stage Cooling & Calendering Unit: Features a large-diameter, precision-chilled roller system to solidify the sheet with excellent surface finish and dimensional stability.

Web Guiding & Tension Control System: Maintains perfect sheet alignment and controlled tension throughout the line to prevent wrinkling or stretching.

Automatic Winding & Cutting Station: Equipped with a turret winder for automatic roll changeover, producing tight, uniform jumbo rolls of finished geomembrane.

Centralized PLC Control System: A user-friendly human-machine interface (HMI) allows for centralized monitoring, recipe management, and data logging of all production parameters.
