🔹 Hydrogen Gas = Hidden Cause of Aluminum Casting Rejections 🔹
Many casting defects don’t come from moulds or machines — they come from Hydrogen gas dissolved in molten aluminum.
When metal is poured, this gas forms tiny bubbles inside the casting, causing:
❌ Porosity
❌ Weak parts
❌ Leakage
❌ Machining failures
❌ High rejection & scrap
✅ The solution is Degassing — removing Hydrogen before casting.
Clean melt = Strong castings = Low rejection.
Many foundries lose money daily just by ignoring this step.
