Optimizing furnace control systems


The debinding step is required to remove the organic binding additives from the green compacts as a prerequisite for sintering. This important processing step in powder technology is a time and energy intensive procedure during which damage can occur when the temperature profile is improperly or awkwardly designed. A simulation model developed at the Fraunhofer IWM makes it possible to calculate internal stresses resulting from the gaseous disintegration of products in components and to identify the critical phases of the debinding process. These findings allow furnace and temperature control to be optimized so that parts can be debound quickly and without defects.
