Process
 Centrifugal casting process is specifically adapted to the production of cylindrical parts. In the
centrifugal casting process, molten metal is poured into a hollow cylindrical mold spinning
about a horizontal or vertical axis at high speeds (300-3000 rpm) generating more than 100 Gs
of centrifugal force. The centrifugal force distributes the molten metal and shapes it into a
tubular casting. Spinning is continued until the metal solidifies. Gates, risers and cores are
eliminated in this process, resulting in maximum yield.
The advantages of Centrifugal Casting
Improved physical properties
Formed under pressures many times that of gravity combined with directional solidification,
two unique characteristics of the centrifugal casting process, the products exhibit a denser,
closer grained structure, with absolutely no porosity. 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.
Longer Life
Parts made from centrifugal process, with the castings’ closer grained, denser structure provide
more reliable service life and withstand greater stress and impact without fracturing.
Due to higher reliability and life of the components produced using this process, total costs over the life of the end product is much lower due to fewer end-of-life/failure situations and lower maintenance.
Competitive Product Pricing and lower lifetime costs
Our unique insight and in-depth engineering expertise in Centrifugal casting process coupled with inherently low metal wastage characteristics of this process allow us to produce highly reliable products at competitive pricing as compared with traditional casting methods such as sand casting.
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.
Minimum Developmental Lead-time and Expense
The molds are made in-house at Vijay Spheroidals which minimizes the lead time in developing
new items and on continuous offtake the customers are free of developmental expenses.
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.
Production Flexibility
The centrifugal process allows economical production of a diversified range of sizes, shapes
and quantities.
