One Die forming technique is to use a conforming die, or a die that has a male portion and female portion to it. The metal is sandwiched in-between the two halves and the male half is pressed into the female half of the conforming die.The two halves are pressed together using a hydraulic press.

Charles Lewton-Brain created the copper piece pictured
here, which was made using the dieforming technique from Brainpress.comAlso, the metal can be pressed into a female half of a die by a pad of Flexane. Flexane has some of the same characteristics of rubber. The metal is sandwiched in-between the flexane and the die. The Flexane is pressed into the die with hydraulic pressure.
This is a technique similar to what is used to mass-produce metal articles used in just about every industry from the auto industry to the aircraft industry.
This technique is also used to produce jewelry and other art made of metal at a much lower cost than what it would cost to mass-produce something for the aircraft or auto industry.
If you are handy around the shop than a hydraulic press used for this technique can be made for about a hundred dollars or less. If you would rather purchase a hydraulic press you could pick up a very good one for around a thousand dollars. I've seen them for sale online on E-bay and at the Bonny Doon Engineering web site.
A great site that includes two plans to build a hydraulic press,one that is similar to the picture below, and the other is a bolt together option that can be put together without any welding.
