Casting comes in many forms and the main types I have seen in production environments are sand casting, dies casting and investment casting. One I was not familiar with until seeing this video was centrifugal casting. The centrifugal casting process is used in making pipes and tube bodies with good mechanical properties to a high quality. The mechanical properties make the end product suited to applications where high internal pressure will be applied such as oil and gas piping or hydraulic cylinders.
This particular video from centrifugal casting manufacturer Spuncast shows centrifugal casting process as well as machining of the cast products to create high quality steel and stainless steel products.
