Multiplier

Hydraulic device of the injection drive with an additional piston accumulator for increasing the holding pressure.

The multiplier consists of a piston with a large-area and a small-area face. The large-area face is pressurized at the end of the casting process with the additional piston accumulator. According to the area ratio the pressure is multiplied on the small-area face towards the drive cylinder of the casting piston in the holding pressure phase.
