Wall thickness refers to the thickness of the walls of a die-cast part. In general, the wall thickness in aluminum die casting can range from 1 mm to 10 mm, depending on the specific application and design requirements. Achieving the right wall thickness is crucial; if it is too thin, it may not be able to withstand operational stresses or manufacturing conditions, while excessively thick walls can lead to increased weight and material costs.

The automotive industry heavily relies on sand-cast engine blocks due to the demanding performance characteristics required in modern vehicles. Manufacturers often utilize aluminum for engine blocks to minimize weight while maintaining strength. Aluminum alloys, such as A356, are particularly favored for their excellent casting characteristics and high strength-to-weight ratio. Iron is another popular choice, known for its durability and resistance to wear, making it suitable for heavy-duty applications.

Precision casting, often referred to as investment casting or lost-wax casting, is a method that allows for the creation of intricate parts with outstanding dimensional accuracy. The process begins with a wax pattern that is coated in a ceramic material. Once the ceramic hardens, the wax is melted and drained away, leaving a hollow shell. Molten metal is then poured into the shell to form the desired component. After cooling, the ceramic shell is removed, revealing a precision-cast product.
