Reducing Dimensional Variation of PM Components throughout the Process Chain
Powder metallurgy is a cost-efficient process route for the production of net shape or near net shape components. In many situations, secondary operations – for instance, sizing or machining operations – are required to meet the tolerance class of the application. Better tolerances of as-sintered components will increase the competitiveness of PM technology by reducing the need for secondary operations. In this presentation, the benefits of advancements in material for dimensional control are discussed. Experimental results are presented that demonstrate how the dimensional variability of components can be reduced.
