Why UAE PVC Plants Prefer Twin Parallel Screw & Barrel Systems
PVC extrusion continues to expand across the UAE, particularly in high-demand segments such as pipes, conduits, profiles, cable ducts, and window frames. To maintain competitive production rates and consistent output quality, factories rely heavily on advanced screw and barrel engineering. Among the most dependable technologies used across Dubai, Sharjah, Ajman, Abu Dhabi, Al Ain, Jebel Ali, and Ras Al Khaimah, Twin Parallel Screw & Barrel Systems have emerged as the preferred choice for PVC processing lines.
Vishwakarma Plast manufactures these systems in Ahmedabad, Gujarat (India) and supplies them across India and the UAE, ensuring the reliability and performance demanded by modern extrusion plants.
This article explains why Twin Parallel Screw & Barrel Systems UAE are now the industry standard for high-output PVC extrusion, and why manufacturers consistently choose Vishwakarma Plast for precision-engineered solutions.
What Makes Twin Parallel Screw & Barrel Systems Ideal for PVC Extrusion?
PVC is one of the most sensitive polymers to process. Its thermal window is narrow, requiring precise temperature control, uniform mixing, and stable shear. Twin Parallel Screw Barrel for PVC applications addresses these challenges through:
1. Advanced Geometry and Pitch Profile
Parallel twin screws feature uniform diameter and optimized helical geometry. This ensures:
- Consistent material conveying
- Higher feeding volume
- Balanced shear distribution
- Smooth material plasticizing
The fine-tuned L/D ratio improves melting efficiency, especially crucial for high-output lines in Dubai and Abu Dhabi that run continuous 24/7 cycles.
2. Feeding Efficiency for High Output
Unlike single or conical systems, parallel twin screws offer a larger feeding area. This enhances:
- Stronger grip on dry-blend PVC
- Reduced slippage during feeding
- Higher throughput per kW of power
This is particularly important for UAE plants producing pipes and conduits in large volumes.
3. Compatibility with High Torque & High NM Motors
Modern PVC extrusion lines in Sharjah, Jebel Ali, and Ras Al Khaimah operate on high-torque motors. Vishwakarma Plast designs screws for:
- Excellent torque transmission
- Low start-up load
- Smooth acceleration and deceleration
- Superior wear resistance under high stress
Parallel twin screws maintain structural integrity even under aggressive torque loads commonly encountered in high-output PVC extrusion.
Technical Advantages for UAE PVC Manufacturer
1. Metallurgy & Materials Built for Durability
To withstand the abrasive nature of PVC compounds, screws and barrels use proven metallurgical grades:
- EN41B nitrided steel for robust core strength
- H13 for high-heat resistance
- D2 tool steel for superior abrasion resistance
- Bimetallic liners for long-life performance
The combination ensures longevity even during high-temperature operations in UAE climate conditions.
2. Precision Heat Treatment & Surface Hardness
Vishwakarma Plast ensures:
- Nitriding depth of 0.5–0.8 mm
- Surface hardness up to 65–70 HRC
- Hard chrome finishing for smooth melt flow
- Deep case-hardening to withstand prolonged wear
The increased surface hardness ensures High Output PVC Screw Barrel UAE plants can operate continuously without premature wear.
3. CNC Machining + Tight Tolerances
All screws and barrels undergo:
- In-house CNC machining
- ±0.01 mm tolerance accuracy
- Profile grinding for perfect alignment
- Bore honing for smooth barrel interior
This guarantees superior melt homogeneity and consistent product wall thickness—critical for PVC pipe producers in Ajman, Dubai, and Abu Dhabi.
4. Barrel Sleeve Hardness & Wear Resistance
Bimetallic barrel sleeves resist:
- Chlorine release from PVC
- Filler-induced abrasion
- Thermal degradation
- High-pressure extrusion loads
The result: longer service life and reduced replacement frequency—ideal for high-demand industrial plants.
5. Enhanced Melt Homogeneity
Parallel twin screws deliver:
- Better mixing and homogenization
- Reduced thermal degradation
- Smoother melt flow
- Improved dimensional accuracy
PVC plants in Al Ain and Sharjah value this stability, especially when processing high-filler compounds or color masterbatches.
