Two Stage Vented Screw Barrel

Experience superior processing control with VS Engineers' high-performance two-stage vented screw barrels!

This innovative technology offers a powerful solution for removing volatile materials and enhancing product quality in various extrusion applications.

Unveiling the Two-Stage Vented Advantage:

Two-stage vented screw barrels are essentially two screws working in tandem:

Stage 1: Feeding, Melting & Conveying: The first stage functions like a traditional screw, efficiently feeding, melting, and conveying the polymer forward.
Stage 2: Dedicated Degassing & Processing: The second stage receives the melt from the first stage and incorporates strategically placed vent ports.

Efficient Removal of Volatile Materials:

The key advantage of vented screw barrels lies in the vent ports:

Eliminating Impurities: These ports allow controlled removal of volatile materials that could negatively impact the processing and final product quality.
Improved Product Consistency: By effectively removing contaminants, vented screws contribute to consistent and high-quality end products.
Enhanced Additive Control: Vent ports can also be utilized for introducing heat or shear-sensitive additives at specific points during the extrusion process.

Applications for Diverse Needs:

VS Engineers’ two-stage vented screw barrels are ideal for a variety of extrusion applications where precise control over volatile materials is crucial:

Moisture-Sensitive Materials: Ensure optimal processing and product quality for materials prone to moisture issues.
