Precision aluminum casting refers to a range of casting processes designed to produce aluminum parts with intricate details and tight tolerances. Common methods include investment casting, die casting, and lost foam casting. Each process has unique advantages, but they all share the ability to produce high-quality parts that can significantly reduce the need for further machining.

Sand casting is one of the oldest and most widely used casting processes in the manufacturing industry. It involves creating a mold from sand and then pouring molten grey cast iron into the mold cavity. The process begins with the preparation of a mold, which consists of two halves the cope (upper half) and the drag (lower half). The sand is mixed with a binder, usually clay, and water to create a mold that can hold its shape when the molten metal is poured.
