Vented Screw & Barrel Set Supplier in Dubai for High-Moisture Materials
For extrusion plants across Dubai, Sharjah, Abu Dhabi, Ajman, Al Ain, Jebel Ali, and Ras Al Khaimah, managing high-moisture raw materials is one of the biggest operational challenges. Excess moisture leads to bubbles, melt instability, porosity, black specs, and frequent production interruptions. The most effective solution is a precisely engineered vented screw & barrel system designed to improve degassing, enhance melt quality, and streamline throughput.
As a leading Vented Screw & Barrel Set Supplier in Dubai, Vishwakarma Plast has become a trusted name among UAE extruder manufacturers and plastics processors. With a state-of-the-art manufacturing plant in Ahmedabad, Gujarat (India), the company supplies high-performance vented screw & barrel sets UAE for PVC, HDPE, LDPE, PP, WPC, masterbatch, and other moisture-sensitive compounds — engineered for continuous industrial operations and long-term reliability.
Why Vented Screw & Barrel Systems Are Critical for High-Moisture Extrusion
High-moisture content in polymer materials disrupts extrusion stability. Vented screw designs integrate a dedicated degassing zone that releases entrapped moisture and volatiles before they reach the metering section. This improves melt quality and enhances overall output.
How a vented screw works
A vented screw typically includes:
- Feed Zone – Material intake and compression begins
- Primary Compression Zone – Polymer begins melting
- Vented Zone (Open Atmospheric Vent) – Moisture escapes under controlled temperature
- Secondary Compression & Metering Zone – Melt is homogenized and stabilized
This structured design ensures that excess water is removed before the polymer reaches the die, preventing defects and maintaining consistent extrusion pressure.
Why venting is essential for materials used in the UAE industry
Many UAE extrusion plants process materials that inherently contain higher moisture levels, such as:
- PVC compounds
- HDPE/LDPE reprocessed granules
- PP compounds and filled masterbatch
- WPC (Wood Plastic Composite)
- Moisture-sensitive recycled plastics
A purpose-built High-Moisture Material Extrusion Screw dramatically reduces the likelihood of melt surging, degradation, voids, and surface defects — especially under Middle Eastern climate conditions where material storage humidity can vary.
Technical Advantages of Vented Screw & Barrel Sets
A vented extrusion system engineered by Vishwakarma Plast delivers quantifiable performance improvements for UAE processors:
✔ Better Moisture Removal
Efficient degassing eliminates trapped moisture, preventing bubble formation and melt porosity.
✔ Higher Output
Because the melt stabilizes earlier, extrusion speed can be increased without compromising quality.
✔ Lower Melt Temperature Fluctuations
Improved thermal control leads to superior dimensional stability and smoother downstream operations.
✔ Improved Melt Quality
Material passes through two compression zones for better homogenization and reduced contamination.
✔ Fewer Moisture-Related Defects
Prevents common issues such as:
- Air bubbles
- Burn marks
- Black specs
- Surface porosity
- Die-line imperfections
✔ Extended Equipment Life
Premium wear-resistant metallurgy such as EN41B nitrided steel, bimetallic barrels, alloy-coated flights, and hardened zones increases durability and reduces maintenance costs.
Collectively, these benefits help UAE industrial buyers increase production stability, reduce scrap, and achieve a more predictable extrusion output.
