In the production of PM components the dimensional scatter must be kept to a minimum. Due to the demand for narrow tolerances the components may need sizing or other secondary operations which increase production costs. New high strength material cannot however be sized due to the high hardness which means that the tolerances after sintering must be very close. This makes it important to consider the scatter in dimensional change when selecting material for PM components.<BR>A model to calculate the scatter in dimensional change is suggested. The dimensional scatter on produced components can be estimated by using a mathematical model. This model includes the variations in mix composition, important compacting and sintering variables. It also take into account the Influence from these variables on the dimensional change.<BR>With this model different base powders, alloys and manufacturing processes can be compared to find the most efficient alternative for achieving the best dimensional precision of PM parts.<BR>The need for lowest total cost coupled with demands for high strength make it necessary to improve the dimensional tolerances for the parts after sintering.
