Degasser Units
Aluminum Degassing Units
Flawless Metal Purity
Gas and residual inclusions dissolved in liquid aluminum cause porosity (gas voids) and structural weaknesses after casting. Our Degassing Units use rotor technology to bring the liquid metal to the highest purity level. This process ensures your parts pass leak tests successfully and maximizes their mechanical properties.
Rotor Technology and Operating Principles
The system injects inert gas (argon or nitrogen) into the liquid metal via a graphite rotor that is immersed in and rotated at high speed. The rotor disperses the gas throughout the metal, breaking it down into millions of microbubbles. These rising microbubbles carry hydrogen atoms and suspended impurities (oxides) from the liquid metal to the surface, providing effective cleaning.
Advantages of Our Gas Removal Units
Key features that guarantee your casting quality:
Eliminates Porosity Risk: By reducing hydrogen levels below a critical threshold, it completely prevents the formation of micro and macro voids in cast parts.
Maximum Sealing Performance: Guarantees sealing standards (X-ray and pressure tests) that are vital, especially for engine blocks and hydraulic components.
Effective Inclusion Removal: Purifies the internal structure of the casting by removing non-metallic contaminants (impurities) from the molten metal to the surface.
Adjustable Processing Parameters: By controlling parameters such as rotor speed, gas flow rate, and processing time via PLC, the same high quality is achieved in every crucible.
Graphite Protection System: Special protection systems that prevent rotor oxidation extend consumable life and reduce operating costs.
Our Product Options
Mobile Gas Removal Units: Flexible solutions that can be easily moved between different crucibles within the foundry thanks to their wheeled structure.
Fixed Station Degassing Units: Fully automated and high-capacity stations installed on the ladle conveyor line in mass production lines.
Crane-Mounted Suspended Gas Removal Units: Heavy-duty systems designed for large crucibles, operated by being attached to a crane hook.
