Centrifugal casting is a metal casting technique that allows you to produce hollow castings without the use of cores. We are specialized in the production of centrifugal castings with horizontal axis for the production of pipes and flanges with axial symmetry.
The liquid metal, poured into a shell of special dimensions and rotating around its axis, is forced by the centrifugal force which develops to adhere to the walls of the form which is cooled until solidification has taken place. It is thus possible to obtain tubes of various thickness in relation to the quantity of metal poured.
In the centrifugal melting process of metals, the rotation speed represents a parameter of considerable importance depending on the centrifugal force on the square of the angular speed. It is determined according to the diameter of the tube, the fluidity of the material and its temperature, through an experimental development process.
As a guide, centrifugal acceleration equal to 50/150 times that of gravity is imposed on the liquid metal. Once introduced into the mold, the metal is subjected to a high cooling rate with consequent rapid solidification which is enucleated on the external surface and proceeds towards the inside of the tube. The centrifugal force of the casting process also favors the concentration of the lighter non-metallic and gaseous inclusions on the internal surface of the casting.
