Rheo Casting
G-Plast is among a select group of manufacturers in India utilizing this advanced technology to address the industry most critical challenges. By implementing this process, we effectively eliminate the inherent issues of internal porosity and thermal instability common in traditional pressure die casting, providing a superior solution for high-performance applications.
Key Technical Advantages of Rheo-casting
- Superior Structural Integrity: The laminar (non-turbulent) filling of the die significantly eliminates gas entrapment and shrinkage porosity, ensuring high-density, leak-proof components.
- Heat Treatability: Unlike traditional high-pressure die casting, rheocast parts can undergo T4, T5, or T6 heat treatments, allowing for significantly higher mechanical strength and ductility.
- Near-Net-Shape Precision: The process enables the casting of complex, thin-walled geometries with excellent dimensional stability, drastically reducing the need for secondary machining.
- Enhanced Thermal Conductivity: By utilizing specialized alloys and achieving a refined microstructure, rheocasting is ideal for high-performance heat sinks and thermal management components in the electronics and EV sectors.
- Extended Tool Life: The lower injection temperature of the semi-solid slurry reduces thermal shock to the moulds, resulting in increased tooling longevity and lower long-term production costs.
GISS (Gas Induced Semi-Solid casting)
The GISS (Gas Induced Semi-Solid) process is an innovative Rheocasting technique engineered to produce high-quality metal slurries characterized by a fine, globular microstructure. By injecting inert gas through a specialized graphite diffuser, the system achieves a unique combination of rapid thermal extraction and intense agitation, ensuring superior grain refinement and consistent material flow during the casting cycle.
