Definitions for "Hydroforming"
A method of forming sheet meal in which the metal is placed on a flexible rubber diaphragm which is supported by oil under pressure. The meal is formed around a male punch as the diaphragm is raised. The result part is generally of uniform thickness and quite strong.
Innovative forming method, whereby a liquid placed under high pressure is used to press the workpiece into a specified shape inside a closed die. This makes it possible to produce extremely complex shapes from tubular blanks.
A manufacturing process that involves pumping fluid into a die, so that the pressure will expand and form a tubular blank, providing many structural advantages.
