Plastivo Launches Highperformance Twinscrew Barrels for PVC PE Extrusion

Plastivo Extrusions has introduced its new high-performance tapered twin-screw barrel system, designed to revolutionize extrusion processes for PVC, PE, and other thermoplastic materials. This advanced engineering solution promises to enhance production efficiency while optimizing product quality across various industrial applications.

The tapered twin-screw barrel system represents a significant advancement in extrusion technology, offering several key benefits:

• Enhanced mixing and homogenization: The unique tapered design creates multiple mixing zones along the screw length, ensuring uniform melting and consistent material properties.
• Exceptional durability: Constructed from high-grade carbon steel with advanced heat treatment processes, achieving surface hardness of HRC 60-65.
• Stable melt flow control: The tapered geometry enables precise compression ratio control and consistent pressure buildup throughout the extrusion process.

The system has been specifically engineered to address the challenges of processing sensitive thermoplastic materials:

• Specialized design minimizes shear stress and thermal degradation in PVC processing
• Accommodates both rigid and flexible PVC formulations
• Adaptable for various polyethylene grades and other thermoplastics

The tapered twin-screw barrel system supports numerous manufacturing applications:

• PVC pipe and profile extrusion
• Wood-plastic composite (WPC) production
• Cable insulation and sheathing
• Plastic compounding and recycling

The system offers customizable configurations to meet specific production requirements:

• Screw diameters ranging from 20mm to 150mm (custom sizes available)
• Adjustable length-to-diameter (L/D) ratios
• Optional specialized coatings for enhanced wear resistance
• Vented and non-vented barrel options

Plastivo Extrusions maintains rigorous quality control throughout the production process:

• CNC precision machining for exacting tolerances
• Deep-hole boring and precision grinding for optimal surface finish
• Advanced nitriding and heat treatment processes
• Comprehensive quality testing including hardness verification and dimensional inspection
