What is centrifugal casting? Centrifugal casting is a liquid forming process in which liquid metal is poured into a rotating mold by the centrifugal force generated by the rotating mold (up to 150 times the force of gravity) and rotated at high speeds (usually 250 to 1500 r/min) so that it fills the mold and solidifies under the action of centrifugal force to form a casting. The process is particularly suitable for the manufacture of marine engine cylinder liner, aerospace and high temperature parts and other harsh working conditions products - more measured data show that the centrifugal casting aluminum alloy pieces of tensile strength than the traditional sand casting to enhance the 25% or more. How Centrifugal Casting Works The centrifugal casting process begins with the injection of liquid metal into a rotating, high-temperature mold. Depending on the specific requirements of the design, the mold can rotate vertically or horizontally. During this process, centrifugal force evenly distributes the liquid metal at a pressure close to several times the force of gravity...
