Centrifugal Casting

Centrifugal Castings At Great Lakes Industrial Solutions Inc.

Centrifugal casting services at Great Lakes Industrial Solutions Inc. produce high-integrity alloy tubes engineered for strength, purity, and demanding industrial environments. By spinning molten metal inside rotating molds, we create dense, uniform components with reliable mechanical performance.

Key technical advantages of centrifugal casting include:

Molten steel is poured into rotating molds, where centrifugal force forms the tube geometry.
High centrifugal pressure drives metal outward, creating dense, sound walls with minimal porosity.
Impurities concentrate toward the inner diameter and can be removed through pull-boring when required.
Chromium- and nickel-rich alloys maintain high purity throughout the casting.
Higher carbon content, typically 0.4–0.5%, can be achieved compared to drawn tubes, which are usually limited to about 0.1%.

Advantages of the Centrifugal Casting Process

Greater Strength

The greater strength of parts produced using centrifugal casting is a result of higher-density grain structures. As the process allows for more control over directional solidification, the grain structure is more uniform, and its mechanical properties are almost equal in all directions. This higher structural density increases the life span of the component and allows for higher stress tolerances. Another factor that contributes to the enhanced part strength is higher product purity, which eliminates internal porosity and improves structural uniformity.

Increased Product Purity

During the casting process, the spinning of the mold places extreme pressure on the molten material. This pressure causes lighter contaminants and impurities to separate from the denser metal. These impurities gather in the bore of the component, minimizing the risk of the formation of weak points or areas of porosity within the metal structure. The machining process following casting removes these impurities, leaving a highly pure end-product.

Better Production Cost-Efficiency

Increased product purity also affects production cost-efficiency. As impurities gather at the interior surface of the part and are machined out, there is a reduction in the number of defective parts and rejects. The lack of porosity produced through the centrifugal casting process also allows manufacturers to use less metal and produce less material waste. In addition, faster setup and shorter production cycle times lead to improved production cost-efficiency.
