Pore-Free Die Casting is an advanced die casting technique designed to minimize internal gas porosity during the solidification process. At ZincAlu, this process is used to manufacture parts that require pressure-tightness, post-machining, or surface coating without the risk of blistering or leakage.

🧪 What Is Pore-Free Casting?

Pore-Free casting works by injecting pure oxygen gas into the die just before the molten aluminium is shot into the cavity. This forms fine oxides that suppresses gas entrapment and minimizes voids or air bubbles in the final product.
