The Mechanics of Directional Solidification

By utilizing high centrifugal forces up to 100G, we eliminate gas porosity and force non-metallic impurities to the inner bore, delivering zero-defect components with refined grain structures.

CENTRIFUGAL PHYSICS

How Centrifugal Force Refines Metal

During rotation, centrifugal force exceeding 100 times gravity forces the heavier, dense molten alloy outward against the mold wall. This intense pressure forces lighter oxides, slag, and gas bubbles to migrate inward to the inner diameter bore.

As the component cools, our precise thermal management ensures directional solidification from the outside in. This progressive crystallization prevents shrinkage cavities, ensuring a completely solid, high-density grain structure ready for precision machining.

METALLURGICAL BENEFITS

Engineered to Outperform Sand Castings

Centrifugal casting produces physical properties that match or exceed those of forged components, without the directional weaknesses of traditional sand molds.

Zero Gas Porosity

Refined Grain Structure

Machined Purity

High centrifugal force eliminates trapped air and gas pockets, producing a uniform, high-density alloy structure that resists high-pressure failures.

Rapid cooling against the metal mold induces directional solidification, creating a fine, equiaxed grain boundary with superior tensile strength.

Because lighter oxides float to the inner bore, we machine away the inner layer entirely, leaving a 100% pure, defect-free metal cylinder.

Bore Machining & Inspection

The mold is coated with a refractory wash and spun at calculated RPMs to generate the required centrifugal force for the specific alloy.

The inner bore containing the concentrated impurities is machined out on our CNC lathes, followed by rigorous NDT testing.

We formulate the alloy in our induction furnaces, verifying the exact elemental composition with our 8-channel spectrometer before pouring.

Molten metal is introduced into the spinning die, solidifying progressively from the outer diameter inward to prevent shrinkage cavities and micro-porosity.
