Method for simultaneously producing first and second piston parts

A method for simultaneously producing a first piston part and a second piston part via a forging device, comprising:

• an upper die, at least one intermediate die and a lower die, and
• placing a first billet between the upper die and the intermediate die, and placing a second billet between the intermediate die and the lower die,
• moving the upper die and the lower die toward each other, whereby the first piston part is forged from the first billet and the second piston part is forged at the same time from the second billet,
• moving the upper die and the lower die apart, and
• removing the piston parts.

A forging device comprising:

• an upper die, at least one intermediate die, and a lower die,
• a first billet placed between the upper die and the intermediate die, and a second billet placed between the intermediate die and the lower die,
• wherein the upper die and the lower die are configured to be moved toward each other, whereby the first piston part is forged from the first billet and the second piston part is forged at the same time from the second billet, and
• wherein the upper die and the lower die are configured to be moved apart, and the piston parts are configured to be removed.

A piston comprising:

• a first piston part and a second piston part,
• an upper die, at least one intermediate die, and a lower die,
• a first billet placed between the upper die and the intermediate die, and a second billet placed between the intermediate die and the lower die,
• wherein the upper die and the lower die are configured to be moved toward each other, whereby the first piston part is forged from the first billet and the second piston part is forged at the same time from the second billet, and
• wherein the upper die and the lower die are configured to be moved apart, and the piston parts are configured to be removed.
