Centrifugal Casting Process

Miller Centrifugal Casting Company (now a wholly owned subsidiary of ESW –Austria) began its life in 1957.
Miller Centrifugal Casting Company produces centrifugally cast sleeves for the hot rolling of structural shapes and tubular products. There are several advantages to the centrifugal casting process compared to the static casting process.
The Centrifugal Casting Process begins with the electric induction melting of high grade materials and close control over chemistry and temperature. After pre-heating the ladles the furnace is tapped and the ladle transported by electric overhead crane to where the mold is rotating at high speed within the spin casting machine. At the correct temperature the shell metal is poured first and after an appropriate time the softer, tougher core metal is poured giving the desired fine grained bi-metallic structure.
