Injection moulding device, multi-component injection moulding process, use of a placeholder element, computer program and computer-readable medium

摘要

The invention deals with improvements in the technical field of the production of multi-component parts (4),a function part (3),in particular a hollow needle, comprising a plastic forming part (2),in particular a syringe cylinder (2),is sprayed. In order to be able to quickly and comfortably re-equip the injection moulding device, it has an interchange device (11) with the function part holder adapted to different function types (7, 8, 9) and/or a functional part holder (8) and a placeholder element (10) may be placed in their position of use in front of a moulding cavity (6) of the injection molding (5) of the injection molding device (1).
