Cover, sump or cap-shaped housing connection part manufacturing method for e.g. oil sump, involves spraying plastic onto elastomer unit for forming housing unit, and durably connecting housing unit to frame-shaped fastening part

摘要

The method involves spraying plastic onto an integrated sealing and sound-damping elastomer unit (12) for forming a housing unit (15), where the spraying of the plastic takes place through a thermoplastic foam casting. The elastomer unit is durably connected to the housing unit, and the housing unit is durably connected to a frame-shaped fastening part (10) for fastening a housing connection part (11) to a motor vehicle unit by using the elastomer unit. An independent claim is also included for a housing connection part for a motor vehicle unit.
