Influence of surface treatment on the bond strength of plastics/metal hybrids
The newly developed “integrated metal/plastic injection moulding” allows the manufacturing of plastics/metal-hybrids combining the injection moulding of plastics with the pressure die casting of metals on one machine. The materials plastic and metal are combined in a specially designed multi-component injection mould. In a first step the plastics preform is moulded. In the second step, the injection of the liquid low melting tin-zinc metal alloy enables the integration of full metal areas, preferably working as electrically conductive tracks. For applications in electric devices a certain bond strength between plastics carrier and metal conductor is demanded. This article is focused on different surface treatment techniques to improve the achievable bond strength between the thermoplastic and the metal component.

The Journal of Plastics Technology is a peer reviewed internet periodical published under the auspices of the Scientific Alliance of Polymer Technology (WAK)
International Polymer Processing, the journal of the Polymer Processing Society, is a discussion forum for the world-wide community of engineers and scientists in the field of polymer processing.
The journal covers research and industrial application in the very specific areas of designing polymer products, processes, processing machinery and equipment.
The Journal of Plastics Technology is indexed in SCOPUS, the largest abstract and citation database of peer-reviewed literature.
