Abstract：Aiming at the large die casting machine, the frequency conversion energy-saving technology solutions are put forward. Based on the design of controller hardware and software, and the application of the non-inductive vector loop torque control technology and double CPU, DSP special energy efficiency system cooperating with die-casting specialized application software, electricity consumption of die casting machine was greatly decreased in circulation in the production at small flow rate condition and the working efficiency of the die casting machine was improved, so that die-casting machine electricity energy was saved. And the frequency conversion energy-saving was applied in 8000 kN die-casting machine, energy saving effect is 41%, the efficiency was increased by 15%, so as to realize technology innovation and the purpose of saving energy, compared with the conventional die casting machine products, electricity consumption can be energy-saving 25%～35%.
Key words：die-casting machine；frequency conversion energy-saving；PLC
