摘要： The invention relates to a method for producing of a form part, especially of a plane thin-walled fiber composite part, in a mould (1), comprising the steps: a) Providing of the mould (1), wherein the mould (1) comprises a cavity (2) with a nominal form volume (V) for inserting of a reactive mixture, wherein the cavity (2) is delimited by at least one cavity wall section (3) which is elastically deformable during the inserting of the reactive mixture and wherein the modulus of compressibility (K) of the cavity (2) is between 2,000 bar and 10,000 bar; b) Inserting of the reactive mixture into the cavity (2), wherein the reactive mixture is inserted with such a pressure into the cavity (2) 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 (3) above the nominal form volume (V); c) Letting solidify of the reactive mixture in the cavity (2); d) Demoulding of the finished form part from the mould (1). Furthermore, the invention relates to a device for the execution of the method.

摘要： A component mixing jet including a jet nozzle housing with at least one component inlet and one component outlet. An axially movable jet needle is arranged in a reception in the jet nozzle housing and can rest against the jet nozzle housing with an axial end in the region of the component outlet in a sealable manner. The jet needle is connected with a membrane fixed in the jet nozzle housing. A pressure chamber is arranged in the jet nozzle housing at the side of the membrane averted from the axial end of the jet needle. The membrane is a holding element for the jet needle and guides the jet needle axially and holds it radially in the reception. The axial region between the membrane and the axial end of the jet needle is free from any bearing element for the jet needle in the region of the component outlet.
