Best 10 casting Factory in China 2025

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 one of the oldest manufacturing processes, dating back thousands of years, and it is widely used in various industries such as automotive, aerospace, machinery, and construction. It offers several advantages, including the ability to create complex shapes, high production efficiency, and cost - effectiveness for large - scale production.
