Abstract The integration and combination of known technologies to one-step-processes is a promising way to implement enhancements to existing processes and products, as well as to new product developments. This approach is followed by two integrative process technologies that were developed by the Institute of Plastics Processing (IKV) at the RWTH Aachen University and the Surface Engineering Institute (IOT) at the RWTH Aachen University as part of the Cluster of Excellence “Integrative Production Technologies for High-Wage Countries”. In these processes, pure metals or metal alloys are joined to the injection moulded part, which potentially results in particular advantages referring to the electrical properties of the product. The integrated metal/plastic injection moulding (IMKS) represents the combination of injection moulding and metal die casting. The in-mould metal spraying (IMMS) combines the injection moulding with the thermal spraying of metal. In the following, the level of development of both methods is presented and future potentials are shown.

Injection moulding is one of the most important manufacturing processes for mass production of complex plastic parts. The quality of injection moulded parts depends not only on the material, shape, and function of the part design, but also on how the material is processed during moulding. Traditional design approaches based on intuition, prior experience, and trial-and-error methodology have been becoming less efficient and effective. With advances in numerical modelling and computer simulation techniques, there have been tremendous efforts made to develop computer simulation tools to facilitate injection moulding design and process set-up. This paper reviews the history of research and development in the filling simulation of injection moulding. The existing models are classified into three categories: one-dimensional models, 2.5D models, and three-dimensional models. The basic features and relative key techniques about these models have been discussed. The techniques of tacking the moving flow front have also been presented. It is then followed by conclusions and discussions of these mentioned models.
