Although various technologies are capable of producing plastics/metal hybrid parts for electrical applications, they all have disadvantages due to several manufacturing steps and limitations in productivity or the level of achievable geometrical part complexity. In addition, the material groups are often regarded separately, particularly when it comes to the materials-related forming processes. One approach to overcome these disadvantages, which is currently examined at the Institute of Plastics Processing (IKV) and the Surface Engineering Institute (IOT) at RWTH Aachen University within the scope of the Cluster of Excellence "Integrative Production Technology for High-Wage Countries", is to combine the plastics injection moulding and the thermal spraying of metals to create a new multi-integrated process enabling the production of plastics/metal hybrid parts. The In-Mould-Metal-Spraying (IMMS) is intended to enable the integration of metallic coatings on plastics parts. In the first step, a metallic layer is applied to specific areas of the mould's surface using thermal spraying, which is immediately followed by the plastics injection. During this second step, the metallic coating is transferred onto the plastics part. The plastics part including the transferred partially metallic coating is then removed from the mould. A strong, permanent connection between the plastics and the metallic coating and an exact outline replication of the metallic coating in the pre-assigned areas are to be realised. To develop and improve the new technology, the influence of different plastics types on the transferability of the metal coating onto the plastics part has been investigated systematically. Furthermore, the influence of the surface structure on the component design is investigated with the help of a test sample featuring a wide range of different surface structures. The results provide valuable information on the favourable process configurations and plastics/metal combinations. [ABSTRACT FROM AUTHOR] |
