Method for producing multi-component part of vehicle

A method for producing a multi-component part (200) of a vehicle includes inserting an air-guiding device (10) having at least one contact portion (40) into a cavity (310) of a tool (300). The methodthen includes heating a composite part (100) having at least one mating contact portion (140) to a melting point of at least one material of the composite part (100), and heating the contact portion (40) of the air-guiding device (10) to a melting point of at least one material of the contact portion (40). The method further includes inserting the heated composite part (100) into the cavity (310)of the tool (300) and pressing the heated composite part (100) into a geometry of the part while simultaneously forming an integrally bonded connection between the mating contact portion (140) of thecomposite part (100) and the contact portion (40) of the air-guiding device (10). 种用于制造车辆的多部件构件(200)的方法，尤其用于车辆底板，具有以下步骤：将至少个空气导流装置(10)插入模具装置(300)的空腔的保持部分中，空气导流装置具有至少个空气导流部分(30)和至少个接触部分，为了压紧过程而将具有至少个配合接触部分(140)的复合构件加热到复合构件的至少种材料
