Sand casting is a metal casting process that involves creating a mold from a mixture of sand, clay, and water. The first step in this process is to prepare the mold. A pattern, typically made of metal or plastic, is pressed into a sand mixture to create a cavity in the shape of the desired engine block. Once the mold is formed, it is aligned and secured, and molten metal, usually made from aluminum or iron, is poured into the cavity. After cooling, the mold is broken away to reveal the cast engine block, which undergoes further machining to achieve the necessary specifications and finish.

Lead castings have a variety of applications across different industries. One of the most common uses is in the production of weights, such as those used for fishing, diving, and balancing applications. Lead's density makes it an ideal material for creating heavy components that require stability without occupying excessive space.

5. Finishing After the metal has solidified, the mold is broken away, and the casting is cleaned and finished. This may involve machining, welding, and surface treatment processes to achieve the desired specifications.
