The main advantages of gravity casting are mold reusability, high surface finish, high dimensional accuracy, and high production efficiency.
This process is particularly suitable for applications requiring low production volumes and high-quality results. Compared to sand casting, gravity casting achieves smoother surfaces and greater efficiency. Since its founding, United Machine has been a trusted brand in the gravity casting industry. We support small to medium-sized batch production.
