What is Centrifugal Casting?

Centrifugal casting is a method used to produce metal products that are tubular, cylindrical, or annular in shape that require high quality, purity, and structural uniformity. Molten metal is poured into a spinning mould, which forces the molten metal to the mould wall. The process is precisely monitored and controlled to assure the correct volume of metal is poured at the calculated flow rate and temperature. As the metal is poured, it conforms to the inside diameter of the mould and solidifies as it cools. Once solidified, the casting can be heat-treated, cut, and machined to customer specifications.

The centrifugal casting process naturally produces high-quality tubes with uniform properties and higher mechanical strength than provided by other casting methods. Centrifugal force causes impurities and lighter oxides to migrate to the inside diameter of the casting which, upon solidification, are easily removed by CNC machining and processing. Advantages of centrifugal casting over other casting methods include:

• Better suited to produce hollow cylinders
• Multiple parts can be made from a single casting
• Stronger and higher quality with exceptional material purity
• Less costly than forgings in most cases

We produces castings with outside diameters from 3 inches to 31 inches and in lengths from 29 inches up to 276 inches. The same mould can be used to produce castings of varying wall thickness and cut lengths. Industries utilizing centrifugal castings include oil and gas, aerospace, marine, defence, and other equipment manufacturers.
