Abstract:
A piston, particularly a piston for use in a diesel engine, particularly a heavy duty diesel engine, is formed from a billet of metal, such that the finished piston has a mass that is at least 50%, and, more preferably, up to about 62%, of the mass of the billet. Other than finishing steps, the piston is formed with a closed gallery, without loss of mass through machining processes.

Claim (Index 1):
A method for forming a piston having a closed gallery, comprising the steps of:\n providing a billet of metal; hot forging the billet, producing a first piston preform having a skirt, a piston pin boss and a crown; hot forming the first piston preform to generate a second piston preform having a flange and an undercut, separated axially by a gallery that is open in the radial direction, the gallery being opened up on the second piston preform without any loss of material; hot bending the flange over the open gallery, generating a third piston preform having a closed gallery; and machining the third piston preform having a closed gallery, generating a finished piston.
