Abstract One of the main advantages of PM technology is its ability to make near net shape components with a cost efficient process. However, variation in the dimensions of products after compaction and sintering that often calls for sizing or machining to reach the desired tolerance class. Bonded organic mixes have been developed to improve the consistency by reducing the segregation of elements in mix and improving the filling characteristics. An improved bonded mix combined with a recently developed lubricant, was evaluated by indutrial production of a complex shape component with tight tolerances. Many benefits of dimenisonal consistancy, weight precision, better lubrication as well as clean surfaces by using the improved bonded mix were presented.
