Models of foundry

The most common process is sand foundry, because it is a refractory material very abundant in nature and, mixed with clay, acquires cohesion and moldability without losing the permeability that makes it possible to evacuate gases from the mold while pouring molten metal .

Sand casting consists of casting molten metal, typically alloys of iron, steel, bronze, brass and others, into a sand mold, letting it solidify and then breaking the mold to remove the cast.
