Twin Parallel Screw & Barrel Set Supplier in Abu Dhabi – Full Guide
A Complete Technical & Buyer-Intent Resource for UAE Plastic Manufacturers
The UAE plastic industry—especially in Abu Dhabi, Dubai, Sharjah, Ajman, Al Ain, Jebel Ali, and Ras Al Khaimah—is continuously upgrading its extrusion lines to achieve higher output, better melt quality, and longer machine life. One component that plays a critical role in PVC, WPC, and pipe extrusion is the Twin Parallel Screw & Barrel Set.
As a leading Twin Parallel Screw Barrel Supplier UAE, Vishwakarma Plast provides high-performance, precision-machined screw & barrel solutions manufactured in Ahmedabad, Gujarat, India and exported to all major UAE industrial hubs. This full guide explains technical specifications, applications, benefits, metallurgy, and how UAE buyers can choose the right set for their machinery.
Why UAE Extrusion Units Prefer Twin Parallel Screw & Barrel Sets
UAE plastic factories operate under demanding conditions—high ambient heat, humidity, and heavy-duty, long-hour production cycles. This makes it essential to use a screw & barrel set engineered for:
- Higher output
- Stable melt flow
- High wear resistance
- Corrosion protection
- Energy-efficient performance
That is exactly where a Twin Parallel Screw & Barrel Set in Abu Dhabi becomes the preferred choice.
Technical Overview of Twin Parallel Screw & Barrel Set
1. Geometry & Mechanical Design
Twin parallel screws are designed with:
- Parallel shaft alignment for stable extrusion
- Optimized compression ratios suitable for PVC & WPC
- L/D Ratio typically from 18:1 to 36:1, depending on machine size
- Specialized mixing, feeding & metering sectio
- Precision-tuned clearances between screws and barrel
This geometry ensures consistent plasticizing with minimal backflow and uniform melt quality.
2. Metallurgy & Surface Treatment
Vishwakarma Plast uses globally accepted metallurgical standards to deliver long-lasting performance.
Base Materials Used:
- EN41B
- D2
- M2

Wear-resistant design results in:
- Fewer replacements
- Reduced shutdowns
- Lower cost per kg of production
5. Energy-Efficient Operations
Better melt consistency reduces motor load, helping reduce energy consumption—critical for UAE’s rising production costs.
6. Compatibility with UAE’s Major Extruder Brands
Suitable for leading brands used across:
- Abu Dhabi pipe plants
- Dubai WPC manufacturers
- Sharjah PVC factories
7. Designed for Harsh UAE Conditions
Engineered to withstand:
- High heat levels
- Dust-heavy environments
Long-hour extrusion
Twin Parallel vs Twin Conical – Which Is Better for UAE?
Parameter | Twin Parallel | Twin Conical |
Output | Higher | Moderate |
Wear Life | Longer | Good |
Mixing Quality | Excellent | Good |
Application | PVC/WPC profiles, pipes, granules | Mostly PVC pipe & small profiles |
Maintenance | Lower | Medium |
Best For UAE | PVC/WPC factories seeking high productivity | Small to mid-sized PVC plants |
UAE buyers focused on high-volume output prefer Twin Parallel Screw & Barrel Sets.
