First, the punches shape the powder into the desired geometry. What makes all the difference here is perfect control that also takes account of punch interaction. No compacting force is applied yet. This stage is vital for the uniform density of the finished part. Next up is the coordinated press compacting process. As a result of the telescopic arrangement of the cylinders, each CPA axis is guided with pinpoint accuracy and can transmit high compacting forces. The hydraulic CNC axes ensure the uniform force of all punches. Furthermore, they compensate for punch expansion, particularly during the relief phase. So you get parts completely free of micro cracks.
