dc.description.abstract In this work, a cellulose acetate butyrate (CAB) and polyethylene glycol (PEG) blend is used as the binder system in a zirconium silicate mineral powder feedstock for powder injection moulding. These irregular zircon powders make the mixing process and the selection of an optimal solid loading level a difficult task. Torque rheology methodologies combined with other techniques are used for evaluation of the parameters affecting the mixing process and determination of the critical powder volume concentration (CPVC). Temperature variations during the mixing process are monitored and used as an indicator of the friction energy of the system and thus for the optimal solid loading selection. There have thus far been limited amounts of work conducted on torque rheology of highly loaded feedstocks that incorporate a study of the system's temperature evolution. A detailed study could be a key factor for understanding the mixing behaviour of highly loaded feedstocks.
dc.description.sponsorship The authors would like to acknowledge the companies GUZMÁNGLOBAL S.L and ALFAMIMTech for their support and partnership in the project IPT-2011-0931-020000 granted from the Spanish Ministry of the Economy and Competitiveness and the European Funds for Regional Development (FEDER). They would also kindly thank the Applied Mechanics Department of FEMTO-ST Institute and the ENSMM (Besançon, France) where some of the experimental works were performed. The suggestions and technical support of T. Barriere and G. Michele were much appreciated.
