Abstract

A method of 3-D shaping at least a portion of a plate like object (30), whereby the object is arranged between two chambers (12, 16) at different pressures. The object is locally heated and a local plastic deformation is realized by means of the force due to the pressure difference at its two sides heated material is heated and deformed by a fluid pressure. A first fluid pressure is provided. This method is very suitable for manufacturing moulds for producing customized contact lenses.
