The oldest known casting process, sand casting, dates back to before 1000 BC. C. Of course, great progress has been made in process control, material selection, tolerance capabilities, the ability to produce precision parts, and a wide range of sizes. 

But the fundamentals of metals have remained relatively unchanged. Create a cavity in the shape of the part you want, and then pour molten metal into it. Examples of Sand Casting After centuries of development, sand casting is the most versatile and possibly the most widely used method of metal casting. When choosing how to manufacture a product, the manufacturing industry determines which metal processing technology (including casting technology) is most suitable.

The technology used in sand casting products can produce molded parts of almost any design, including very large parts and parts with internal channels. Based on the following factors, there may be a more optimized casting or metallurgical process for any particular product: the necessary tolerances, the design complexity, the availability of batch tools, and the delivery time. However, the required configuration of the casting is likely to be manufactured by the sand process. 

This is a decision left to the design engineer. This process is called sand casting because the mold containing the cast metal cavity is made of compressed or compacted sand. Sand contains some other materials that can encourage it to maintain its shape.
