Abstract

A cranium is firstly produced form an epoxy resin, whose thickness is adapted so that the compressive strength at a given point is the same as at the corresponding point of a real cranium. This is followed by the fitting of the soft parts, i.e. the brain, eyeballs, flats of the ear and nasal pyramid. These members are made from a silicone to which a variable quantity of oil has been added to ensure that their hardness is the same as that of the corresponding real organs. The cranium is then placed on a support permitting the correct orientation thereof in the mould where the skin is cast.
