During tilt pour filling (or “tilt casting”), a manufacturer connects a crucible (also called a “pour basin”) directly to mold gates. These openings in the mold lead to a network of interior sprues allowing molten material to flow inside the mold cavity. A slow rotation of both the crucible and the gating system enables liquefied metal to fill the mold completely. This tilting movement reduces problems associated with abrupt filling, which may accidentally trap air pockets inside the interior. Today, automation permits close control over the tile pour process.
