The invention relates to a method for producing of a form part, especially of a plane thin-walled fiber composite part, in a mold (), comprising the steps: a) Providing of the mold (), wherein the mold () comprises a cavity () with a nominal form volume (V) for inserting of a reactive mixture, wherein the cavity () is delimited by at least one cavity wall section () which is elastically deformable during the inserting of the reactive mixture and wherein the modulus of compressibility (K) of the cavity () is between 2,000 bar and 10,000 bar; b) Inserting of the reactive mixture into the cavity (), wherein the reactive mixture is inserted with such a pressure into the cavity () so that the cavity volume is increased during the insertion of the reactive mixture due to elastic deformation of the at least one cavity wall section () above the nominal form volume (V); c) Letting solidify of the reactive mixture in the cavity (); d) Demolding of the finished form part from the mold (). Furthermore, the invention relates to a device for the execution of the method.

Method and device for producing of a form part

The invention relates to a process and a device for the production of polyurethane clock foam, in which the reaction mixture, after flowing through a mixer, flows freely from an outflow opening and then flows through an accumulation chamber, in which a static pressure is built up, a gap and finally an expansion chamber.
