Development of an innovative manufacturing technique for cold isostatic pressing

Objective

Ceramic components are nowadays successfully used respectively tested in many fields of the European industry. A very common original forming process to get components out of a ceramic powder is cold isostatic pressing (CIP). Expensive equipment with pressure levels up to 4000 bar are necessary to obtain high-grade components with a high and homogeneous density. The goal of the project is the development of cyclic cold isostatic pressing as a usable powder compaction process for SMEs. This way, reliable, big sized and complex shaped ceramic components shall become producible by SME's in small and medium lot sizes. For the manufacturing process special press functions are to be developed for the compaction, which allow a decrease of the maximum pressure level by about 50 %. Primary RTD goals are: . conception and construction of the different kinds of superimpositioning cycling pressure during CIP, . optimisation and specification of the press functions (frequency, amplitude, maximum and minimum pressure, as well as the start of the pressure oscillation,...) investigations of the reached properties (microstructure, density, strength,...) . optimisation of components of the facilities referring to the stress cycles endured and proof of the system safety
