sand casting and investment casting_sand casting and investment casting

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.

1. Enhanced Surface Finish One of the major advantages of dry sand casting is its ability to produce superior surface finishes. The customization of sand grain size and choice of binder allows manufacturers to achieve smoother finishes, which reduces the need for extensive machining and post-processing.
