Vacu2
Multi-Stage Vacuum Process. The Revolution in Die Casting!
In our new Vacu2 multi-stage vacuum process, the shot sleeve and mold cavity are evacuated in two stages. During the first stage, the air is extracted directly from the shot sleeve via a wide cross-section line. This enables the desired pressure to be quickly achieved in the shot sleeve and mold. In the second evacuation stage, the air is extracted directly from the mold, as in the case of conventional processes.
Since the desired pressure has already been achieved in the first stage, the second stage serves to maintain the pressure by pumping down air that leaks into the mold. The control system processes pressure measurements that are taken in four different locations at different points in time during the casting process into process-relevant data. This affords precise information about the current status of the system. Should any limits, some of them can be defined by the user, be exceeded or not reached, the system responds with warning signals. This avoids unnecessary rejects.
Vacu2 reduces costs in your die casting process!
Advantages
- Better vacuum translates into optimum quality
- Reliable process monitoring reduces the rejection rate
- Faster process optimization and better designed molds as low as vent valves reduce your costs
