Top 10 casting Factory in China

Introduction to Casting

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. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. Casting is used to create complex shapes that would be difficult or uneconomical to make by other methods. It has a wide range of applications in various industries such as automotive, aerospace, machinery, and construction.
