At ICAST ALLOYS LLP, we specialize in the manufacturing of high-precision Open and Closed Impellers through the lost-wax investment casting process. Combining decades of metallurgical expertise with state-of-the-art casting simulation, we deliver impellers that define the standard for hydraulic efficiency, structural integrity, and durability.
At ICAST ALLOYS LLP, we challenge the industry standard that investment casting is only for small, intricate parts. Through continuous innovation and investment in high-capacity infrastructure, we have mastered the art of producing bulky and heavy-weight investment castings that maintain the signature precision and surface finish of the lost-wax process.
From massive pump housings to heavy-duty valve bodies, we provide "near-net-shape" solutions for components that were traditionally restricted to sand casting or expensive forging.
We don't just cast bigger; we cast better. Our facility in Rajkot is equipped with specialized machinery designed to handle the unique thermal and structural demands of large-scale molds.
Weight Range: Capability to cast components from 15 grams up to 85 kilograms (185 lbs).
Dimensional Envelope: Maximum casting dimensions up to 600 x 600 x 650 mm.
Infrastructure: * 15-Ton high-capacity wax injection presses.
1500 mm diameter big-volume slurry mixers for consistent shell coating.
1650 mm sand rainfall machines for robust mold building.
Custom-designed autoclaves and robotic conveyor systems for seamless movement of heavy shells.
| Feature | The ICAST Advantage |
| Material Versatility | We cast heavy components in Stainless Steel, Carbon Steel, Alloy Steel, Nickel Alloys, and Aluminum Bronze (AB2). |
| Complex Geometries | Large parts often have internal passages; we achieve intricate internal structures without the need for extensive machining. |
| Cost Efficiency | By delivering a near-net-shape product at 75kg+, we significantly reduce your raw material waste and secondary machining costs. |
| Rigorous Testing | Every heavy-weight casting undergoes meticulous sampling and process planning to ensure structural integrity and zero defects. |
Our bulky casting expertise is the backbone of critical industrial applications where durability and precision are non-negotiable:
Oil & Gas: Heavy-duty valve bodies, diffuser housings, and manifold components.
Pumps & Valves: Open and closed impellers, large-scale gate valves, and pump casings.
Marine & Defense: 24-inch bronze boat vent sliders and structural defense components.
Power Generation: Turbine components and high-pressure steam valve parts.
"Challenge Accepted"
“At ICAST, we don’t shy away from size. Whether it’s a non-symmetrical shape or a 40kg impeller with 8-inch wall thickness, our team combines years of experience with advanced simulation to deliver record lead times without compromising quality.”
Max Shell Capacity: 400 shells handled simultaneously.
Tolerances: Adherence to strict VDG P690 (D1/D2) standards even at large scales.
Surface Finish: Achieving 6.3 Ra (N9) or better, reducing the need for post-cast polishing.
Don't let size limit your design. Partner with ICAST ALLOYS LLP for heavy-weight investment castings that offer the perfect balance of scale, strength, and sophistication.
