What is Prototype Sand Casting?

CNC sand casting is a two-step process. First, a mold is created using sand, which is typically mixed with a binding agent to ensure its stability. The mold is shaped in accordance with the design specifications of the desired part, often using CNC machines to ensure precision. Once the mold is prepared, molten metal is poured into it, allowing it to solidify and take the shape of the mold. After cooling, the mold is broken away to reveal the cast part.

The applications of aluminum sand castings are vast and varied. In the automotive industry, components such as engine blocks, transmission cases, and bracket supports are frequently made using this method. The aerospace industry also relies on aluminum sand castings for critical components that require both strength and lightweight properties. Additionally, consumer products such as cookware and outdoor fixtures benefit from the durability and design flexibility of aluminum sand castings.

Once the pattern is prepared, the sand mixture is packed around it to form the mold. The following steps outline the typical sand casting process
