Abstract
The invention relates to a process for manufacturing a thermoplastic part ( ) with an injected seal ( ) as well as to an injection molding apparatus and a corresponding thermoplastic part. For injecting the seal, a groove ( ) is formed during molding of the thermoplastic part ( ) in which groove liquid crosslinked plastic as material for the seal ( ) is injected. Sealing projections ( ) are formed on the groove edge and/or on the injection mold in order to prevent an overflowing beyond the groove edges during injection. When closing the mold, undercuts ( ) are formed on the upper edge of the groove for holding the solidified seal ( ) in the groove.
