UAE Maintenance Tips – Complete Guide to Customized Screw & Barrel Set
By Vishwakarma Plast – Ahmedabad, Gujarat, India (PAN-India & UAE Supplier)
The UAE plastic manufacturing sector—spanning Dubai, Sharjah, Abu Dhabi, Ajman, Al Ain, Jebel Ali, and Ras Al Khaimah—is rapidly growing, driven by high-output extrusion, injection moulding, and blow moulding demands. With rising production speeds and increased material expectations, the need for a Customized Screw & Barrel Set has never been higher.
Whether you manage large extrusion halls in Jebel Ali, operate injection moulding lines in Sharjah, or run packaging units in Ajman, a customized set ensures maximum melt quality, output stability, and long-term durability. As a leading UAE screw barrel supplier, Vishwakarma Plast supports the region with precision-engineered solutions from our advanced manufacturing plant located in Ahmedabad, Gujarat, India—supplying PAN India and exporting consistently to the UAE.
This guide delivers essential screw & barrel maintenance UAE tips while explaining how customization improves performance, reduces downtime, and increases ROI for plastic processors across the Emirates.
Demand for Customized Screw & Barrel Sets in the UAE Plastic Industry
The UAE industrial expansion has triggered a strong shift toward high-efficiency, application-specific screw and barrel systems. The region now demands:
- High-output extruders for pipes, profiles, WPC, and films
- High-pressure injection moulding machines for automotive, household, electrical, and packaging parts
- Energy-efficient blow moulding lines
A Customized Screw & Barrel Set ensures that each machine—whether Chinese, European, or Indian—delivers maximum melt homogeneity, wear resistance, and stable torque output based on the specific raw material, speed, and temperature requirements used in the UAE.

- Bi-metallic Alloy (Colmonoy / Tungsten Carbide Coating) – 1.5–2.5 mm thick coating for extreme wear resistance in high-output applications.
Hardness, Nitriding & Coating Specifications
- Nitriding Depth: 0.4–0.6 mm uniform layer
- Surface Hardness: 65–70 HRC
- Barrel ID Hardness: 58–62 HRC
- Bi-metallic Layer: Up to 2.5 mm for long wear life

Advantages of Custom Design for UAE Processing Units
A Customized Screw & Barrel Set gives UAE plastic units complete control over performance parameters:
1. Custom Compression Ratio
Improved melt quality and pressure build-up for specific polymers like HDPE, LLDPE, PVC, ABS, PP, and PA.
2. Optimized L/D Ratio
Higher L/D enables better mixing, improved output, and stable melt temperature—critical for high-volume lines in Dubai and Jebel Ali.
3. Wear-Resistant Coatings
Bimetallic coatings extend life when processing abrasive fillers commonly used in the UAE.
4. High-Output Screw Geometry
Barrier screws, Maddock mixers, pineapple mixers, and custom channel depths boost overall production efficiency.
5. Energy Efficiency & Long-Term Durability
Reduced torque load and optimized melting reduce electricity usage—essential for UAE’s cost-sensitive industrial plants.
UAE Maintenance Tips – Complete Guide to Screw & Barrel Longevity
Proper maintenance dramatically extends the life of any Customized Screw & Barrel Set, especially in UAE’s high-temperature environment.
1. Regular Cleaning
- Purge after every material change
- Use approved purging compounds
- Avoid metal scrapers to prevent surface scoring
2. Wear Detection
Monitor for:
- Output reduction
- Increased melt temperature
- Pressure fluctuations
- Black specs or unmelted granules
Early detection prevents costly machine downtime.
3. Corrosion Prevention in UAE Climate
The UAE climate accelerates rusting due to heat and humidity.
Best practices include:
- Apply anti-corrosion oil during shutdowns
- Store barrels in a controlled environment
- Keep heater bands properly insulated
4. Lubrication Schedule
- Weekly lubrication of drive-end bearings
- Use high-temperature lubricants for extruders in Dubai & Abu Dhabi regions
- Ensure gearbox oil is replaced at recommended intervals
5. Knowing When to Replace
Replacement is required when:
- ID wear exceeds 0.5 mm
- Output drops by 15–20%
- Overheating becomes frequent
- Backpressure becomes unstable
6. How Customized Sets Reduce Maintenance
A well-designed customized screw improves:
- Melt homogeneity
- Wear resistance
- Stable torque load
- Reduced shear heat
This results in 40–60% lower maintenance frequency for high-output UAE units.
