What manufacturing process involves pressing moist sand around a pattern to create a mold?

The process that involves pressing moist sand around a pattern to create a mold is known as sand casting. In sand casting, the pattern, which is usually made of metal or another durable material, is placed in a mold box and surrounded by sand mixed with a binding agent. The moisture in the sand helps the grains stick together, allowing for the formation of a solid mold cavity. Once the sand has hardened, the pattern is removed, leaving behind a mold that can be filled with molten metal to create the desired part.

This method is widely used due to its ability to produce complex shapes and accommodate large products, making sand casting a fundamental technique in manufacturing, especially in industries such as automotive and aerospace.
