Applications of Precision Casting

The primary ingredients of green sand consist of silica sand, clay, water, and sometimes additional additives. The silica sand serves as the backbone of the mixture, providing the necessary granular structure. The type of silica sand can vary; however, it is important to choose sand with good strength and refractoriness. A fine grain size is often preferred as it allows for finer details in the castings and ensures better surface finish.
