The strength of Forgings with the efficiency of Casting
See the Difference. Compare Metal Forgings to Centrifugal Casting
Forging is a process where thermal and mechanical energy is applied to a block of a solid metal (i.e. an ingot) to cause the alloy to change shape while in a solid state. Casting is a process where metal is heated in a furnace until molten and while in the liquid state, is poured into a die, or mold, to create a component shape.
The casting process is far simpler and requires fewer resources. By solidifying uniformly under high pressure, centrifugal castings combine the chemical and mechanical property capability of forgings at a significantly lower cost.
Additionally, the defect-free tight grain structure of centrifugal formings makes them well suited for pressure containing and anodized applications. JCT optimizes this technology with custom chemistry, versatile casting and complete machining capabilities.

Centrifugal forming is also far superior to a sand casting!
- The centrifugal process directional solidification avoids porosity and inclusions associated with centerline shrinkage defects in sand castings.
- The material used to riser the centrifugal process is fed to the casting at 60 times the force used to feed a sand casting.
- The solidification is fed by a huge surface area of high pressure molten metal rather than through a complex network of narrow gates and risers.
- The JCT process uses solid, high chill rate mold materials rather than pressed and glued particulate molds.
- Surface examination of a machined centrifugal can completely qualify a part contrasted with expensive radiographic, ultrasonic or magnetic particle inspection required to determine the soundness of a sand casting.
