Description Of JDS Artificial Grass Extrusion Line

Core Technology & Working Principle

The extrusion line employs a dual-screw, dual-die configuration specifically engineered for processing polypropylene (PP) and polyethylene (PE) raw materials—polymers widely recognized for their durability and weather resistance in synthetic turf applications. The key workflow involves:

Melting & Mixing: High-quality resin pellets, blended with color masterbatches, are melted and homogenized under precise temperature control.

Dual-Color Extrusion: A specialized co-extrusion system with high-precision dies enables simultaneous extrusion of two colored polymers, ensuring uniform color distribution throughout the yarn structure.

Curling Formation: Through a proprietary high-speed thermal deformation nozzle and air heating system, filaments undergo controlled texturizing to develop stable curly patterns that mimic natural grass morphology.

Cooling & Winding: Equipped with a single-head conveyor cooling system and automatic tension-controlled winding, the line ensures consistent yarn quality from extrusion to finished bobbin.

Key Advantages

One-Step Production: Eliminates intermediate processing steps by integrating melting, extrusion, texturizing, and winding into a continuous workflow, reducing production time by up to 30% compared to conventional systems.

Precision Control: Features metering pump pressure tracking systems and PLC-based inverter controls for main motors, ensuring stable yarn dimensions and uniform crimping even at high production speeds.

Enhanced Durability: Double-roll heating control in the texturizing section reduces yarn moisture content, significantly improving crimp stability and resistance to UV degradation and wear.

Flexibility: Adaptable to various raw materials (PP/PE) and customizable for different crimp patterns, pile heights (7–18mm), and color combinations to meet specific turf requirements.
