CIC is a technology suitable for producing large and complex parts from metal powders. Sintering of the powder requires the use of a container for which the absence of reaction with the powder is essential. The design and manufacture of these containers is a major challenge for the development of the CIC. The aim is to design and validate innovative interfaces that ensure that there is no connection between the container and the compacted part that would ensure easy removal of the container. The numerical simulation of the ongoing powder/container deformation of CIC will be done through the use of the LPS model for high temperature viscoplastic behavior. It is envisaged to simplify experimental model adjustment protocols. Moreover, the digital chain to be implemented requires taking into account the fact that an increasing complexity of the shape of the parts to be made goes hand in hand with an increase in the necessary knowledge. We will adopt a step-by-step approach in improving the models envisaged and manufacturing technologies, in order to be able to take into account all powder/container deformations The strength of the COMPO project lies in the complementary skills of the partners Manoir Framatome SCGI Foundry Collignon URCA and UB. It offers a structured framework where everyone has the responsibility to tackle the technological lock for which they are specialised.
