Multi-component injection-molded part with material-locking sealing

摘要

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 H1 into the composite element and forms a narrowed cross section in the composite element having a height H2. 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.
