This project aims at developing and designing a new die-system capable of reducing the ejection force after in-die compacting and sintering, similar to the functional principle of a Micro-FAST sintering process. The system is based on the shrink-fit principle from cold forging; thus, the die is in a pre-stress condition during sintering. The experimental phase has involved the production of aluminium micro gears either with or without the shrink-fit application. The resulting ejection forces have been compared, showing a reduction with the shrink-fit application.In addition, the influence of several elements on the ejection force has been analysed, such as pressure, time,temperature, and lubrication.
