Abstract
A process for manufacturing products made of foamed polymeric material, comprising the following steps: generating, via software, a virtual model (M) of a product to be manufactured in a solid foamable polymeric material; performing a topological optimization via software of the virtual model (M) in order to obtain an optimized virtual model (MO) with areas of differentiated relative density; preparing the foamable polymeric material and inserting it in a mold (); solubilizing, under pressure, at least one foaming agent in the foamable polymeric material placed in the mold () with a pressure profile of the foaming agent variable over time and/or space as a function of the topological optimization; releasing the pressure in order to obtain a product (S) made of foamed polymeric material provided with the above-mentioned areas of differentiated relative density; removing the product (S) made of foamed polymeric material from the mold ().
