3. Weight Reduction Aluminum is known for its lightweight properties, making it an ideal material in industries such as automotive and aerospace where weight reduction is critical for performance and fuel efficiency. Precision casting allows manufacturers to create thin-walled structures without sacrificing strength.

The first step in the sand casting process is to create a pattern, which is an exact replica of the object to be cast. This pattern can be made from various materials, including wood, metal, or plastic, and it is often designed to be slightly larger than the final product to account for material shrinkage during cooling.
