FAQ
How does the multi-stage vacuum process work?
In our multi-stage vacuum process, the shot sleeve and mold cavity are evacuated in two stages. In the first stage, the air is extracted from the shot sleeve via a wide cross-section line to quickly achieve the desired pressure. In the second stage, air is extracted directly from the mold. This two-stage evacuation ensures rapid and efficient air removal, preventing air inclusions in the castings.
How does the control system optimize the process?
The control system processes pressure measurements taken at four different locations at various points of time during the casting process into process-relevant data. This provides precise information about the current status of the system, avoiding unnecessary rejects and significantly reducing costs in die casting processes.
