Abstract (en)

[origin: DE19719321A1] In order to produce a steering wheel with a low mass moment of inertia, a process is disclosed for casting a plastic material around a metallic steering wheel skeleton. The process is characterised in that the steering wheel skeleton and a predetermined amount of a thermomer plastic granulate, in particular polypropylene or polyethylene, mixed with foaming agents, are introduced into a steering wheel mould, and the granulate is heated up to at least 100 DEG C. The granulate particles are foamed, molten and bonded within the steering wheel mould, forming a steering wheel body which surrounds the steering wheel skeleton. The steering wheel body is foamed within, outwardly provided with a substantially closed surface and has a specific density of less than 0.4 g/cm<3>.
