centrifugal casting

Centrifugal casting is a metallurgical process where molten metal is poured into a rapidly revolving mold. This spinning action uses centrifugal force to distribute the metal evenly, filling the mold and solidifying into the desired shape.12

This method is particularly useful for creating long, hollow objects like pipes without the need for internal cores. It's also employed for casting small, precious-metal items, ensuring that nearly all the metal is used in the casting itself rather than in sprues or risers. The process is a specific type of casting, which is a fundamental technique in metallurgy for producing metal parts by pouring molten metal into a mold.2
