Multi-Stage Vacuum Process. Innovative Solutions for Reliable and Efficient Die Casting. Two stages – One system: Exact. Fast. Efficient. The purpose of vacuum in a die casting system is to evacuate a given volume of air from the mold cavity and the shot sleeve within the shortest possible period of time. This avoids air inclusions in the castings. 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...
