The concept

Back-pressure casting is a casting method for the production of high-quality aluminum cast parts. It is characterized by the fact that both the furnace chamber and the die space are pressurized. This can result in a very high pressure difference being achieved after mold filling. Both factors lead to a significant improvement in quality and therefore to improve component properties.

Along with higher quality, the higher level of automation, and an optimized cycle time, a considerably better material yield is achieved with the back-pressure method than with conventional die-casting.

The variable-speed hydraulics offer low noise emissions as well as large savings in energy costs. The Siemens S7 controller ensures simple operation and transparent data output of the machine and casting controller.
