Rubber Hot Feed Screw & Barrel Set Supplier in UAE: Complete Guide
Rubber processing industries across Dubai, Sharjah, Abu Dhabi, Ajman, Al Ain, Jebel Ali, and Ras Al Khaimah rely heavily on durable, high-performance screw and barrel systems to maintain continuous extrusion, mixing, and reprocessing operations. Among these components, the Rubber Hot Feed Screw & Barrel Set plays a critical role in ensuring stable material feeding, efficient plasticization, and uniform discharge.
For procurement managers, plant owners, OEMs, and maintenance engineers searching for a trusted Rubber Hot Feed Screw & Barrel Set Supplier in UAE, understanding the technical parameters, metallurgical properties, and performance benefits is essential. This guide provides complete clarity—supported by the manufacturing expertise of Vishwakarma Plast, a leading Indian manufacturer exporting premium screw-barrel solutions to the UAE rubber industry.
Understanding Rubber Hot Feed Screw & Barrel Sets
Hot feed rubber extruders operate differently from cold-feed extruders. They process pre-heated rubber compounds, which require a robust screw and barrel capable of handling:
- High material viscosity
- Elevated temperatures
- Abrasive fillers such as carbon black, silica, and mineral powders
- Continuous high-pressure processing
A Rubber Hot Feed Screw features a deep-flighted design and a large root diameter to provide consistent intake and uninterrupted discharge.
Core Functions
- Efficient feeding of pre-heated rubber sheets
- Compression and homogenization of rubber compo
- Controlled shear generation to maintain consistency
- Uniform pressure generation at the die head
- High output rate even under demanding conditions
For UAE factories involved in rubber hose extrusion, tread extrusion, sealing profiles, gaskets, footwear production, and reprocessing units, the reliability of the screw-barrel system directly impacts productivity.

These specifications ensure compatibility with a wide range of UAE rubber processing machinery, including legacy OEM systems and modern high-output lines.
Metallurgy & Material Grades Used
Selecting the right steel grade ensures durability under continuous high-stress operation. Vishwakarma Plast uses premium, industry-approved alloy steels.
Common Materials
- EN41B (Nitro-Alloy Steel) – Best for nitrided screws
- EN24 / 4340 – High-tensile steel for heavy-duty use
- EN31 (Bearing Steel) – Exceptional wear resistance
- D2 / H13 Tool Steel (Optional) – Extreme abrasion protection
These steels maintain structural integrity even when exposed to carbon-filled rubber and aggressive chemical additives.
Wear-Resistant Surface Treatments
Rubber compounds often contain abrasive fillers (carbon black, silica), which quickly wear out untreated screws and barrels. Vishwakarma Plast leverages advanced surface engineering techniques:
1. Gas Nitriding
- Case depth: 0.40–0.70 mm
- Surface hardness: 58–62 HRC
- Ideal for heavy-use UAE rubber processing lines.
2. Hardfacing / PTA Welding
- Coatings: Stellite, Colmonoy 56/6, Ni-based alloys
- Extends screw life 2–3× in abrasive compounds.
3. Chrome Plating
- Reduces friction and material sticking.
4. Bimetallic Barrel Liners
- NiCrB alloy options
- Superior wear and corrosion resistance
These treatments drastically reduce downtime and maintenance costs for UAE factories.
Barrel Manufacturing Capabilities
The barrel must match the screw’s geometry and withstand continuous internal pressure. Vishwakarma Plast ensures precision with:
- Deep nitrided or bimetallic options
- CNC machining ±0.01 mm tolerance
- High-precision honing
- Integrated cooling channels
- Barrel lengths up to 4,000 mm
Built to perform in the demanding environments of Dubai, Sharjah, Abu Dhabi, and Jebel Ali.
