Abstract

For the use of the vacuum die-casting process, it is an essential precondition that the casting process takes place in a circuit sealed off on the outside, so that the undesirable ingress of air is avoided, corresponding safe sealing systems are necessary. The sealing between a casting piston and a suction box is designed in such a way that a long service life of the seal is ensured and a possible risk of accidents is avoided.
