摘要:
The invention relates to a method for producing a thermoplastic part (1) with an injected seal (3), to an injection molding device, and to a corresponding thermoplastic part. For injecting the seal, a channel (2) is formed during molding of the thermoplastic part (1). Liquid cross-linking plastic is injected into said channel as material for the seal (3). Sealing projections (12) are configured on the edge of the channel and/or on the injection molding tool in order to prevent the channel from overflowing during injection. When closing the tool, undercuts (6) are formed on the upper edge of the channel which hold the solidified seal (3) in the channel.
