Centrifual Casting Process

K C Engineering operates two horizontal casting machines, 1,800mm and 700mm in diameter. The maximum design load for our centrifugal casting machines is 2,000 Kgs and we hold up to 4,000 Kgs of whitemetal alloy.
To ensure perfect bonding of whitemetal to the backing material we only use a submerged tinning process in a 8,000 Kg pure tin bath, 2.5m x 1.5m, serviced by two 5 tonne overhead cranes. Provided it is feasible we will always centrifugally cast any manufactured or repaired bearing in order to achieve a higher quality product, for several reasons:

• Dirt, oxide and gas are moved to the inside of the casting, where they are removed on machining
• Shrinkage porosity is eliminated by centrifugal force
• Metallographic structure is improved by directional solidification
• Shorter cooling times reduce crystal growth during solidification
