A liquid filter housing which comprises a housing pot of two-layered configuration and a housing cover closing the housing pot. The housing pot and the housing cover mutually enclose an interior, wherein the inner layer of the housing pot facing the interior is manufactured from an electrically conductive plastic material and the outer layer of the housing pot facing away from the interior from an electrically insulating plastic material. An especially good mechanical connection is achieved between the two layers by the inner layer and the outer layer being connected to one another in a positive-locking manner.

Plastic housing

An injection-molded part according to the invention has at least one thermoplastic inlay part and one thermoplastic composite element injection-molded onto the inlay part. The at least one inlay part on its boundary face with the composite element has at least one raised feature for material-locking sealing between the inlay part and the composite element. The raised feature protrudes with a height Hinto the composite element and forms a narrowed cross section in the composite element having a height H. The at least one raised feature, on its flux leading end, has a first chamfer, and the ratio of the height of the narrowed cross section to the height of the raised feature is in the range between 0.6 and 0.9.
