Development of ceramic injection molding (CIM) enables complex part shaping at high production rate. During the latter, a matrix composed of several polyolefins and waxes is highly filled with fine ceramic powder and shaped by injection molding. The organic binder is then removed via solvent and thermal debindings and the ceramic is sintered. Parts quality is characterized by high sintered density and dimensional stability during the whole process. Due to the complexities of CIM process and binder formulation, numbers of parameters influence the part’s behavior during each step of the production [1]. Penetration, porosimetry and mechanical tests allow the evaluation of binder-binder and ceramic-binder interactions, providing information on polymer matrix structure. Variations of selection and contents of binder’s components highly influence its architecture, leading to modifications of mechanical and physical properties of CIM parts. [1] M.C.
