Increasing energy efficiency in die casting machines
Die casting machines require high forces in a rough production environment. With a relatively short cycle of only 7.5 seconds and negligible auxiliary process times, the previous concept was based on two uncontrolled pumps for high and low pressure.
The Rexroth 4EE Solution
The manufacturer of a die casting machine with a clamping force of 50 tons opted for a Sytronix SvP 7000 variable speed pump drive when the machine series was updated. It consists of a synchronous servo motor, an intelligent servo drive, an internal gear pump, as well as all necessary software functions.
By using Sytronix, energy consumption was reduced by around 84 percent from 11 kW to only 1.7 kW at identical cycle times. At the same time, the manufacturer was able to significantly decrease the number of components needed for the hydraulic system.
