Compacting of multi-level parts made of ceramic powder materials
Abstract
A study of Fraunhofer IWM in Frieburg that outlines the differences between the compaction of a seal disk made of silicon carbide (SiC) on a mechanical multi-axis press and the compaction of the same on a hydraulic CNC multi-axis press, is presented. The company made studies for Lauffer investigating the compacting procedure of an axis-symmetrical seal ring based on the Finite Element Analysis and by means of compaction models developed at IWM. A proportional press concept was chosen that is typical for hydraulic CNC presses for the first simulation. Trial runs were carried on a Lauffer powder compacting press model VPM 63 SC in multi-axis design. The machine allows to control the complete compacting sequence by means of the hydraulics which in turn offers further flexibility to better match the pressing sequence.
