Abstract
A device and method for expansion forming of an article used in conjunction with an isostatic press comprising a pressure cell equipped with an elastomeric membrane. The expansion forming tool has at least one pressure intensifier and at least one molding cavity. A blank is arranged in the molding cavity and an elastomeric forming body is arranged inside the blank. The pressure intensifier is arranged such that it is acted upon by the elastomeric membrane and it exerts pressure on the elastomeric forming body inside the blank inside the molding cavity so that the blank is expanded into an article shaped according to the shape of the molding cavity.
