Advanced RHEO Casting Facility – Roots Cast

Roots Cast Private Ltd., is a leading provider of advanced Aluminium casting solutions, with a strong focus on RHEO Casting technology. Our RHEO Casting facility is designed to produce high-quality, pressure-tight, and structurally sound Aluminium components. By using cutting-edge semi-solid casting techniques, we deliver superior mechanical properties and enhanced thermal performance across a wide range of industrial application components for Automotive, Electronics and Industrial Equipment. Roots Cast offers reliable and scalable solutions for the casting needs.

What is RHEO Casting?

RHEO Casting is a specialized semi-solid metal (SSM) casting process that uses a controlled slurry of Aluminium alloy with a specific solid fraction, which is injected into a die under high pressure. Unlike traditional die casting, which uses fully molten metal, RHEO Casting operates at temperatures lower than the melting point of the material.

Benefits of RHEO Casting:

We have designed and developed our assembly lines in a manner that allows us to have maximum efficiency with Poka-Yoke to prevent defects. We assemble parts using robust equipment and automated processes very efficiently and accurately. We develop and assemble the following child parts with our castings:

  • Thin Wall Castings: Capable of achieving wall thickness as low as 1.8 ~ 2.0 mm, enabling lightweight components without compromising structural integrity.
  • High Thermal Conductivity: Ideal for applications such as Heat Sinks and Automotive EV Power Electronics Housings, where efficient thermal management is crucial.
  • Improved Mechanical Properties: Parts exhibit enhanced strength, elongation, and toughness, resulting in superior durability.
  • Complex Geometries: The process allows for intricate and complex geometries to be cast with high precision, suitable for components that require functional integration.
  • Pressure-Tight Castings: Roots Cast ensures leak-free components, making it the ideal solution for critical applications like Pumps, Compressors, and Hydraulic Systems.
  • Extended Die Life: RHEO Casting processed with lower melt temperature, which reduces die soldering and thermal fatigue, extending the die life by 30 ~ 50%.
  • Reduced Die Casting machine tonnage than normal: Approximately 30 to 40% reduction in Die Casting machine Tonnage.
  • Weldable Components: RHEO Cast parts are weldable, providing more flexibility for post-casting processes.
