Precision You Can Rely On
At Kaivanya Extrusion Technik, we engineer every injection molding barrel to deliver maximum durability, uniform heat transfer, and flawless performance under the toughest production environments. As a trusted partner global injection moulding screw barrel manufacturer, our goal is simple — to help processors achieve consistent output and longer equipment life with world-class barrel designs.
Whether you are running general-purpose molding or advanced engineering polymers, our barrels are optimized for precise barrel temperature injection molding, ensuring perfect melt homogeneity and stability in every cycle.
Hardening Process of Barrel Injection
| 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 |
Built for High-Performance Plasticization
The injection molding barrel plays a crucial role in maintaining pressure, temperature, and melt uniformity. That’s why Kaivanya designs its barrels with a focus on thermal balance, hardness, and wear resistance. Each barrel is manufactured using high-grade alloy steel and reinforced with specialized coatings like PTA tungsten carbide and HVOF surface protection — extending its lifespan by 2–3 times compared to conventional nitrided barrels.
In combination with our precision screws, Kaivanya’s injection molding screws and barrels deliver excellent melt quality, improved plasticization, and reduced power consumption — optimizing your entire injection process from start to finish.
Smart Thermal Engineering
Controlling barrel temperature in injection molding is critical for achieving consistent melt flow and part quality. Our barrels are designed with precision temperature zones to ensure even heating and minimal heat loss across the length of the barrel.
With barrel heater injection molding compatibility, Kaivanya barrels maintain stable thermal performance even during high-output operations. This ensures reduced material degradation, faster start-up times, and consistent part quality throughout production.
