Zusammenfassung:	One or more electro-hydraulic forming tools are operated by a press and provide formed parts to a trimming operation. A locking mechanism holds the die against the chamber during the electro-hydraulic forming (EHF) discharge. The lock may be a pin or clamp. One method of manufacturing an article includes providing three EHF tools that feed a single trimming press on a line. An alternative embodiment discloses a single EHF tool that supplies parts on a production line to an electro-hydraulic (EH) trimming tool. An electro-hydraulic pulse generator may be used to provide a stored charge to the EHF tool and the EH trimming tool.
