Traditionally, wiring harnesses are devices made of many manually assembled components like cables, connector housings, grommets, electronic components… In these applications, “Polyurethane foam” is often used for sheeting wiring harness components such as connectors and cables.
Polyurethane foam is also used to foam special components, e.g. grommets, directly to the wiring harness.
This paper describes the possibility of using polyurethane foam molding technology to integrate functions regarding passive safety systems into vehicles. Due to the fact that polyurethane foam delivers excellent results regarding energy absorption, we have tried to overfoam wiring harnesses in these critical areas with special polyurethane foam.
Due to the elimination of fastening elements and labor savings at the OEM, integrating crash pads into the wiring system offers considerable potential for cost reduction.
