Built to Last – Designed to Perform
At Kaivanya Extrusion Technik, we believe the extrusion barrel is more than just a housing — it’s the backbone of your production line. Every melt consistency, pressure build-up, and extrusion quality starts here. As a leading extrusion barrel manufacturer, we specialize in crafting barrels that redefine durability, precision, and performance for a wide range of polymer applications.
Whether for a single screw barrel or a twin screw barrel configuration, our bimetallic technology ensures exceptional wear resistance, superior heat transfer, and consistent output. Trusted by global OEMs and processors alike, Kaivanya’s barrels are designed to deliver productivity that lasts.
Extrusion Barrel Heat Treatment and Bimetallic Components
| Extrusion Heat Treatment | Spin Cast Inlay Layer Bimetallic Barrel |
| Gas Nitrided/ Plasma Nitrided | Boron inlay layer 1.5 to 2mm |
| PM Tool steel vacuum hardened | Tungsten (10 to 35 %) inlay layer 1.5 to 2mm |
| Hard Chrome/Tin Plating | PM Tool steel vacuum hardened throughout hardened |
The Power of Bimetallic Innovation
Our bimetallic barrels are engineered using advanced metallurgy and cutting-edge surface protection technologies. Each barrel undergoes specialized processes — from tungsten carbide inlay spin casting to HVOF (High Velocity Oxygen Fuel) coating — ensuring an ultra-hard inner layer that withstands abrasion, corrosion, and thermal fatigue.
What sets our plastic extrusion barrels apart is our proprietary inlay layer technology with up to 2.0 mm of tungsten carbide coating, offering wear protection that lasts up to three times longer than conventional nitrided barrels. These coatings maintain their integrity even under high pressures and temperatures, delivering consistent extrusion quality across every cycle.
Precision at the Core
Kaivanya’s approach to extrusion barrel design revolves around one principle — perfection in alignment and precision. Each extruder barrel for sale is manufactured on advanced CNC machining centers, ensuring flawless concentricity between the screw and barrel.
We also offer barrels in a range of premium bimetallic barrel materials, including high-alloy tool steels, nickel-based alloys, and wear-resistant composites — each chosen based on your specific polymer type and operating environment.
The result? Barrels that not only enhance melt homogeneity but also minimize backpressure, reduce energy consumption, and extend overall machine life.
Single or Twin – We Build for Every Application
- Single Screw Barrels: Ideal for extrusion and injection molding, our single screw barrels are vacuum-hardened and optionally nitrided or coated for high corrosion resistance. Perfect for processing PVC, HDPE, and PP, these barrels ensure steady melt flow and uniform temperature control.
- Twin Screw Barrels: Designed for high-output and compounding lines, our twin screw barrels come with modular liner options and PTA tungsten carbide coatings for exceptional endurance. Whether co-rotating or counter-rotating, Kaivanya’s twin screw systems deliver precision feeding, better mixing, and longer operational life.
Crafted for Performance and Productivity
Our production philosophy goes beyond standard manufacturing — it’s about engineering trust. Each extrusion barrel is inspected under strict quality parameters for straightness, surface hardness, coating adhesion, and dimensional accuracy.
Kaivanya’s bimetallic barrels also come with plasma or gas nitriding options, achieving surface hardness up to 1300 HV with deep case hardening — ensuring stable performance even under continuous 24/7 operations.
Every detail is designed to make your system more efficient — from our optimized extrusion barrel design to our high bonding strength coatings (up to 70,000 PSI adhesion).
