Front wall lining producing method for motor vehicle, involves tempering surface area of foam tool before or during injection of reaction mixture into tool cavity such that molded part has open-pored surface or sound penetratable membrane |
摘要 |
<p>The method involves producing a lining (1``) as an expanded, sound proof molded part through injection of a reaction mixture containing polyol and isocyanate into a cavity of a foam tool. A predetermined surface area of the foam tool is tempered before or during the injection in such a manner that the molded part has a thickness of 0.5 millimeter and has an open-pored surface (1.2) or a thin sound penetratable membrane (1.4). An independent claim is also included for a light, soundproof lining for a body part of a motor vehicle.</p> |
