MATERIALS OF CYLINDER LINER

Why Use Centrifugally Cast Material?

The centrifugal casting process involves pouring molten metal into a spinning die and allowing the metal to solidify over time while the die continues to rotate at a high velocity. The metal is literally spun to the outside of the die, leaving a hole in the center and ultimately creating a cylindrical metal tube.

Centrifugal castings are superior to static castings because the casting process results in a more consistent crystalline structure in the metal, drastically reducing the potential for casting defects and impurities in the metal. Through the effect of the g-force applied to the metal, heavier metal is spun to the exterior of the tube and any impurities essentially “float” to the inside diameter of the casting, and are machined away.

Centrifugal casting saves material and processing time in the production process, so our price is more advantageous.
