Casting is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. You are given a task to fabricate an engine block. In your own words, explain how to fabricate it using any suitable four types of processes which can be used and discuss the benefits of each processes
