In this work an experimental setup will be established by SECO Tools to be used for study the powder behaviour and for the characterisation of the die filling as part of the process in powder pressing. Building powder measurements equipment jointly with advanced dynamic measurements using digital speckle photography (DSP) of powder filling is likely to improve the knowledge of a critical part of the process. Measurements will also support development of numerical models. Experimental studies combined with simulations is then likely to improve the understanding of the filling stage, e.g. to explain the non-homogeneity of the density of powder pressed parts.
In the project, studies of different numerical methods as discrete element method (DEM) and smoothed particle hydrodynamics (SPH) method will be in focus. The methods are used to study powder flow behaviour and velocity fields.
The project is founded by Seco Tools and Sandvik
