Abstract

A cellular product having a required shape and density is produced by extruding foamable liquids which are made sensitive to magnetic fields. The foam is subjected to at least one force field during the forming process. Specifically, numerous kinds of foamable substances can be used, e.g. polymer materials comprising a number of urethane groups.
