<p>A method of forming a hollow workpiece (40) particularly made of metal in which the workpiece is placed between at least two parts (32, 33) of a die set; the parts are closed together so that the workpiece conforms approximately to the shape of the interior surfaces (45, 45') of the die set; a solidifying fluid (70) is then injected into the material at a greater pressure than applied outside the workpiece by the die.</p> |
