LBI produces high quality centrifugal cast components based on specific non-ferrous alloys, special steels or composites with a metal matrix and made as per your requirement.
The Centrifugal Casting (or spun casting) process in metallic tooling under very high acceleration, produces a casting using centrifugal pressure. This pressure creates, within the alloy, a very important degassing, which rejects all the impurities, potentially contained in a liquid metal melt, towards the bore.
The one-direction cooling and solidification of the alloy are perfectly controlled.
Vertical centrifugal casting (or vertical spun casting): heavy parts, whose diameter is generally more important than the length, are produced using vertical centrifugal casting machines
Horizontal centrifugal casting (or horizontal spun casting): long parts are produced using horizontal centrifugal casting machines
LBI can supply different part profiles such as: tubes, crowns, rings, sleeves, etc. for various applications: pressure vessel component, radioactive waste storage or transport packaging, submarine mast or surface vessel, pump body, autoclave body, chromatography column body, etc.
Centrifugation is mainly reserved for hollow cylindrical parts (rings, tubes, etc.). The raw external profile, generally of revolution, can be stepped (several different diameters), with flange(s) or even conical shapes.
The bore, which is cylindrical because cores are not used, is obtained by the quantity of metal introduced into the centrifugation shell.
The large fleet of tools, of more than 1,500 shells, makes it possible to achieve the dimensions and shapes requested very closely enabling an economical solution with little waste.
The combination of induction melting and centrifugal casting (or spun casting) process leads especially, as far as austenoferritic steels are concerned, to very high quality levels, similar to those obtained on parts cast under vacuum or with AOD converter.
Centrifugal casting is an alternative to forging or to wrought processes: ring rolling, stamping and open-die forging.
Centrifugal casting consists of pouring liquid metal into a metal coquille/mould under high acceleration (> 50g). LBI produces components by horizontal or vertical centrifugal casting. The solidified alloy, under the effect of the centrifugal pressure, has a fine and homogeneous structure.
Centrifugal castings are an alternative to forgings in several sectors such as nuclear, defence, shipbuilding, machine tools… We offer different centrifugal casting pieces made of stainless steel, copper based alloys or aluminium in different shapes and sizes.
