This paper presents the results of research that is being carried out into the investment casting process between DePuy Johnson & Johnson and the University of Birmingham.
Work currently being performed in three of the seven active modules that are underway within the project are presented in this paper. This paper will focus on research performed as part of the Process Modelling and Simulation, Wax and Shell Modules. The latest investment casting simulation and modelling techniques are being used to target casting defects within the DePuy Cork foundry. The Wax module is also leveraging a similar simulation package to analyse wax flow and behaviour. The Shell Module presents baseline tests which will ensure the effects of all future process improvements are fully understood. Research in these areas is taking place as well as ongoing cost saving projects which will significantly reduce foundry running costs.
This project is a four year FP7 EU Marie-Curie Program “Advancing the state-of-the-art in the investment casting of orthopaedic devices” (MedCast, GA number 251269).
