Workshop on simulation of Powder Injection Moulding (PIM) - progress and expectation of industry

21/11/2008

In order to reach the market in more complex parts, PIM industry requires the use of efficient simulation tools in order to set up the process of injection, debinding and sintering.

The development of bi-components PIM parts requires more urgently an accurate simulation. Indeed, due to the difference of shrinkage between both materials, macroscopic distortion and also internal stresses can easily appear and lead to unacceptable parts for industrialisation.

It is one of the objectives of the project FP6 CarCIM(1) to evaluate the potential of the existing tools to assist the development of bi-components injection-moulding parts. In the project MatLaw better material models and the quality check of feedstocks during injection moulding are developed. During this workshop, it is expected to present an up-to-date status on the simulation of the different stages of the process of fabrication of PIM parts. These steps include the injection, the debinding, the sintering and also the process optimisation.

The workshop is not only addressed to PIM specialists but more on industries which would like to implement the simulation in-house for the improvement of their process of fabrication of PIM parts.
