Manufacturing and Investigation of Precision Powder Injection Moulded Parts

摘要

The improvement of replication accuracy is still an important topic for progress in PIM as it often limits the applicability of the process. Simulation of the filling and cooling steps might help to enhance performance. Another approach is based on a modified process conduct with implemented compression steps which, as further improvement, enables the reduction of membrane thicknesses compared to unmodified powder injection moulding. As an example for precision micro PIM parts ceramic nozzles to be used in experiments with X-ray free-electron lasers are explained. Challenging features are the outlet diameter below 100μm and the internal guiding structures. Such nozzles are required to generate a strongly focused liquid jet of the analysis sample perpendicular to the beam of intense femtosecond X-ray pulses.
