It should be noted that, for any powder-based manufacturing process, the measurement technique used to characterize the powder should be as close as possible to the process.
Humidity and temperature can have a huge impact on a powder flowability. Being able to control those parameters could help you improve your quality control and the predictability of your tests.
For example, the setting of solid bridges due to pre-sintering will have drastic consequences on the packing behavior of the powder. Even at a lower temperature far from the melting point, slight changes in the surface state of the particles will modify the contact interactions and thus the ability of the grains to reorganize during packing. Knowledge of the packing behavior in the processing condition is a requirement to predict the performance of the powder and optimize the processability.
If you wish to have more information about those results, do not miss our next webinar about the environmental conditions of a test. In this webinar, we will show results at several humidities with the GranuMidity which is our humidity conditioner for the GranuCharge as well as high-temperature results on the GranuDrum and the GranuPack.Click for more information and registration
