Publication number: 20210331360Abstract: The invention relates to an injection-molding process for the production of an injection-molded element, comprising a film element and an in-mold-coating layer directly injected onto said element. The film element occupies only part of the area of the in-mold-coating layer, and therefore at least one portion of the film edges of said film element is located in the middle of the relevant area of the injection-molded element. In order to avoid notching in the boundary region, the process for the production of the injection-molded element utilizes dynamic temperature control for locally restricted heating of the mold in the region where the flow front of the in-mold-coating material encounters the film material. Injection-molded elements are thus obtained in which no optically discernible boundary is present between film element and in-mold-coating layer. Because there are no joints, the injection-molded elements are amenable to successful and durable subsequent coating.Type: ApplicationFiled: August 27, 2019Publication date: October 28, 2021Inventors: Roland Kuenzel, Peter Capellen, Thomas Grimm
