A method of fabricating an instrument panel includes providing a skin which forms a surface of the instrument panel and has side face portions extending rearwardly from a front face portion and providing a panel core having a recess for defining a molding space between the panel core and the skin. The front face portion and the side face portions define a bend angle. The recess of the panel core has peripheral walls for engaging the side face portions and the peripheral walls and a surface of the recess define a regular angle which is less than the bend angle. The bend angle, for instance, is larger than the regular angle by 2.degree. to 8.degree., and preferably by 3.degree. to 5.degree.. The panel core is placed in a first die and the skin is place in a second die such that the side face portions are deflected to fit into the recess of the panel core during mold closing. The dies are closed and a foaming material is injected between the panel core and the skin to integrate the panel core and the skin. The side face portions resiliently engage the peripheral walls to prevent leakage of the foaming material. In an embodiment of the method, a skin holding member is movably provided in the second die for holding the side face portions in position during mold closing. The skin holding member is withdrawn to permit engagement of the side face portions with the peripheral walls after mold closing.

[ What is claimed is:] [1.] A method of fabricating an instrument panel comprising the steps of:providing a skin formed with a front face portion to serve as a face surface of the instrument panel and side face portions extending rearwardly from the front face portion at end edge portions thereof and defining a bend angle subtended by the side face portions and a rear surface of the front face portion;providing a panel core having a recess for complementing a contour of the skin to define a molding space between the panel core and the skin, the recess having peripheral walls for engaging the side face portions of the skin when the skin and the panel core are engaged together, the peripheral walls and said rear surface of said skin subtending a regular angle when the side face portions of the skin are fitted into engagement with the peripheral walls of the panel core, and the regular angle being less than the bend angle;situating the panel core in a first die of a mold;situating the skin in a second die of the mold such that the side face portions are fittable into the recess of the panel core during mold closing;closing the mold and engaging the side face portions with the peripheral walls to define the molding space between the panel core and the skin; andinjecting a foaming material into the molding space between the panel core and the skin to thereby integrate the panel core and the skin with a foaming layer formed by the foaming material.
