Abstract: “The paper introduces a new concept in sheet metal forming, which is multichannel sheet hydroforming technology. The new con cept assures an improving of the flexibility of the hydroforming technology as well as an increasing of the productivity. This concept is based on the use of a high fluid pressure that is transmitted through a number of channels to the same number of defor mation cells. The experimental and numerical results validate the new technology concept.”
