Injection Screws – Precision That Powers Every Mold
At Kaivanya Extrusion Technik, we understand that the injection screw is the heart of every molding system. It defines the plasticization quality, consistency, and efficiency that manufacturers rely on. That’s why we craft each injection molding screw with unmatched precision, superior metallurgy, and years of engineering expertise.
As a trusted injection moulding screw barrel manufacturer, Kaivanya Extrusion delivers high-performance screws that optimize melt quality, reduce cycle time, and extend equipment lifespan. Whether you produce packaging, automotive parts, or medical components — our screws ensure your material flows flawlessly, every time.
Hardening Process of Screw Injection
| Extrusion Heat Treatment | Wear Resistance Bimetallic Screw |
| Gas Nitrided/ Plasma Nitrided | PTA Boron (Full Length) Colomony 56/63 Ni/Cr 1.5mm layer |
| PM Tool steel vacuum hardened | PTA Tungsten 20 to 50 % (Last Zone/Entire) Colomony 88/83/705 |
| Hard Chrome/Tin Plating | HVOF thermal spray coating (88 % Wc 12 cobalt) Flight od and core |
Precision-Driven Design for Every Application
Our injection mold screws are tailored to meet the exact requirements of modern injection molding machines. Each screw is crafted using specialized materials and advanced coating technologies to ensure maximum wear resistance and consistent output.
From general purpose injection molding screws to customized barrier designs, Kaivanya’s engineering delivers precision in every turn. The unique geometry of our screws ensures better melting, homogenous mixing, and higher throughput, reducing energy consumption while maintaining excellent product quality.
Material Science Meets Manufacturing Mastery
What sets our injection molding screws apart is our deep understanding of metallurgy and coating technology. Using bimetallic construction, each screw is built to withstand extreme processing conditions, including high temperatures, abrasive fillers, and corrosive polymers.
We utilize advanced coatings such as PTA tungsten carbide, boron carbide, and HVOF hard surface treatments that ensure high hardness (up to 1300 HV) and long-term stability. These processes make our injection screws 2–3 times more durable than conventional nitrided designs — resulting in lower maintenance and higher machine uptime.
