Title: METHOD FOR PRODUCING A MULTI-COMPONENT INJECTION MOULDED PART
Abstract:
The invention relates to a method for producing a multi-component injection moulded part (1), wherein a first plastic component (10) is produced by means of a first injection moulding step, and wherein a second plastic component (11) is at least partially sprayed or overmoulded on the first plastic component (10) by means of a second injection moulding step, so that a material composite is formed by the two plastic components (10, 11). According to the invention, at least one part of an edge region (12) along the dividing line (13) between the two plastic components (10, 11) is heated with a heat source (14) in order to seal the two plastic components (10, 11) together in the edge region (12).
