摘要
A plastic moulded part 10, particularly a carper for a motor vehicle, comprises at least one low-load region 1 for accommodating relatively low loads which is formed using thin-wall technology and at least one high-load region 2 for accommodating relatively high loads which is formed using plastic foam technology and connected to at least one low-load region. A medium-load region may further be provided. The low load region preferably has a wall thickness of less than 1.2mm and the high-load region may have a foam core with a plastic shell and extends along a load path. Preferably, the regions are bionically designed to be structure-optimised. A multiple-stage method may be used for forming the part wherein the low load region may be manufactured by means of extrusion, deep-drawing, compacting or injection moulding. The combination of thin-wall and plastic foam technology make it possible to strengthen high-load regions in a targeted manner and reduce the weight of low-load regions.
