In the aluminum die-casting industry, hydrogen gas trapped in molten aluminum is a common issue. If not removed, this gas causes porosity, reducing the strength and finish of the final product. One proven solution to this problem is the use of GBF/RGB degassing shafts.
GBF (Gas Bubbling Flux) and RGB (Rotating Gas Bubbling) shafts are advanced tools used to remove dissolved hydrogen gas from molten aluminum. The shaft introduces an inert gas—such as nitrogen or argon—into the melt. As the gas bubbles rise, they carry hydrogen and impurities to the surface, which are then removed from the system.
Using GBF/RGB shafts offers several advantages:
Additionally, rotating shafts (RGB) enhance the contact between gas bubbles and metal, which increases degassing efficiency compared to static systems.
Effective degassing is crucial for industries that require:
For example, automotive and aerospace industries demand flawless quality, and degassing helps meet those expectations.
At PT Wilisindomas Indahmakmur, we provide reliable GBF and RGB shaft systems to optimize your aluminum die-casting process. Our products are designed for:
Degassing with GBF/RGB shafts is a simple yet powerful step toward better casting results. Not only does it remove hydrogen effectively, but it also improves productivity and product quality.
