Both investment casting and centrifugal casting can produce high-quality, near-net-shape parts. One of the key differences is that investment casting utilizes one-use ceramic molds that are broken off the cooled parts, while centrifugal casting employs permanent dies that are reused. In addition, centrifugal casting dies are spun at high RPMs to achieved designed casting properties. Investment casting is a static process that relies on gravity to flow the alloys.
