Cast iron sand, also known as foundry sand, is derived from the natural silica sands. This type of sand is specially treated and processed to be used in metal casting applications, particularly in the making of molds and cores. The primary components of cast iron sand include quartz, clay, and other additives that enhance its casting properties. These materials are chosen for their ability to withstand high temperatures, provide excellent mold detail, and facilitate easy removal of the final cast product.

The process of investment casting begins with creating a wax pattern of the desired component. This pattern is then coated with a specially formulated ceramic shell, which hardens upon application. Once the shell is set, the wax is melted away, leaving a precise cavity for the molten metal. This method allows for exceptionally tight tolerances, often within a few thousandths of an inch, making it suitable for components that require high accuracy and reliability.
