Product description

Highlights at a glance

A Counter-rotating Parallel Double Screw Extruder is a specialized polymer processing machine characterized by two parallel screws that rotate in opposite directions within a single barrel.

Unlike co-rotating extruders which are designed for high mixing speed, counter-rotating systems are engineered for low-shear, high-pressure performance, making them the industry standard for heat-sensitive materials.

1. Working Principle

1) Positive Displacement: The opposite rotation of the screws creates a "calendering" effect, trapping material between the screw flights and the barrel to force it forward with high volumetric efficiency.

2) Low Thermal Stress: Because the screws do not generate the intense frictional heat found in co-rotating systems, the material maintains its physical properties without thermal degradation.

3) Venting & Degassing: These machines are often equipped with vacuum exhaust zones to remove moisture and volatile gases, which is critical for high-quality final products.

2. Common Applications

1) PVC Processing: The most widespread use, including rigid pipes (U-PVC), window profiles, and siding.

2) Wood Plastic Composites (WPC): Ideal for compounding wood fibers with plastics due to superior moisture removal and compression.

3) Recycling: Efficiently processes 100% recycled materials into high-quality profiles.

3. Advantages

1) Modular extruder concept with high process flexibility for various formulations and materials

2) Low maintenance effort thanks to internally tempered screws and air-cooled barrel

3) High output rates, reliable degassing, and consistent production of single- and multi-layer pipes with excellent quality

Certifications & compliance
