Multi-Stage Vacuum Process Vacu² revolutionizes Die Casting

 

For many years, die casting has been a proven and tested process in the industrial mass or series production of structural parts for various applications. In this process, a liquefied material – the so-called "melt" – is pressed into a mold cavity where it then solidifies.

Many foundries use vacuum for this process. In a joint project with the consulting and development company for foundry, Glimo N.V., Pfeiffer Vacuum developed a groundbreaking multi-stage vacuum process for die casting – the Vacu².

The goal during the development of this process was set high: The plan was to create a revolutionary vacuum process in die casting, which eliminates the disadvantages of existing processes in terms of the vacuum reached, the process safety and process control. This plan was based on a synthesis of scientific and practical expertise – by carrying out calculations and simulations as well as extensive practical tests and measurements.

Vacuum in die casting
The task of the vacuum system 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 casting. Vacuum has been used in die casting for several decades now.
