N2 - Powdered metal parts molded from CW0350 mix were observed to explode during the sintering process. This, in turn, has caused a high scrap/material waste during production. This study was conducted to determine the root cause in order to reduce the amount of scrap created from exploding parts by at least 2%. Part samples were tested at different furnace conditions (sintering temperature, atmosphere, and belt speed) and then compared to a controlled sample ran at typical router specifications. When the results of the tests were compared to the standard, the samples that ran with an increase of 50CF hydrogen, a 50°C increase in temperature, or a 1.0 inch/min slower belt speed showed the highest percentage of success. These tests yielded zero exploded parts during their run which reduced the fall out percentage from an average of 6% to 0%.
