Investment casting, also known as lost-wax casting, is one of the oldest techniques and is widely favored for its ability to create complex shapes with smooth surfaces. Here, a wax pattern is coated with a ceramic material. Once the ceramic is hardened, the wax is melted away, leaving a cavity that is then filled with molten aluminum. This process allows for high detail and accuracy and is often used in industries where precision is paramount, such as aerospace and medical devices.

The primary function of casting sand suppliers is to deliver a product that meets the specific needs of the foundry industry. Suppliers must understand the nuances of different sand types and their applications. For example, fine grained sands provide excellent surface finishes, while coarse grained sands might be preferable for large, thick-walled castings. Furthermore, their knowledge of sand treatment techniques, including reclamation processes, enables them to offer tailored solutions to their customers.
