Abstract

Electro hydraulic Forming (EHF) is a high speed forming method suitable for small series production of 3D sheet metal parts. The particular advantages of EHF are low cost tool technology, increased material formability, and minimal spring back. EHF of sheet metal components offers new possibilities for producing advanced components for machinery applications. This article describes the EHF process and the potential of EHF as a rapid prototyping method for sheet metal part production. The motivation is to get a breakthrough of this production technology. In additional, new design, process simulation methods and verified material models are needed. EHF technology in Finland (VTT and LUT) is based on a long-standing cooperation and technology transfer programme with the University of St. Petersburg (Russia).
