KDP Alloy Centrifugal Casting, Shape : Round for Industries

ADVANTAGES OF THE CENTRIFUGAL PROCESS

What are centrifugal castings? Centrifugal castings are sometimes referred to as liquid forgings. The centrifugal

casting process is unlike other foundry processes in that it requires special knowledge, practices and skills not

usually found in other types of foundry operations.

In the centrifugal casting process, molten metal is poured into a hollow cylindrical mold spinning about a

horizontal or vertical axis at speeds generating more than 100 Gs of centrifugal force. The centrifugal force

distributes the molten metal and shapes it into a tubular casting.

Improved Physical Properties formed under pressures many times that of gravity combined with directional

solidification, two unique characteristics of the centrifugal casting process, parts made from centrifugal exhibit

a denser, closer grained structure with vastly improved physical properties. Because of high structural

uniformity, physical properties such as tensile strength, yield strength, elongation, reduction of area, and other

desirable properties are improved by up to 30% over conventional gravity or static casting methods. 6 | P a g e

Longer Life Parts made from centrifugal, with the castings' finer grained, denser structure provide increased

service life and withstand greater overloads and impact without fracturing.

Reduced Rejects As the molten metal is poured, centrifugal forces distribute the molten metal against the walls

of the mold with tremendous force, thereby displacing the lighter oxides and impurities, causing them to

surface on the inside diameter of the hollow cylinder being cast. The trapped oxides and impurities are easily

removed in the machining process.

Pattern Expense Eliminated The extensive inventory of molds available at CCI eliminate the customer's expense

of buying, storing, maintaining and insuring patterns.

Reduction of Manufacturing Costs as a result of the uniformity and other desirable characteristics of centrifugal

castings, machining time and material waste are significantly reduced. Hard spots, sand residue, cavities,

blowholes and porosity are virtually eliminated.

Production Flexibility The centrifugal process allows economical production of a diversified range of sizes,

shapes and quantities. Faster Delivery Due to the short mold set up and preparation time required for

centrifugal castings, delivery can be scheduled to meet the customer's needs. The customer benefits from

reduced manufacturing lead time and avoids the high cost of maintaining inventory.
