A study on simulation of a water-hydraulic system for a molding press.

A simulation model of a water-hydraulic molding press was developed, considering static and dynamic characteristics of a power unit, a ram cylinder, a servo valve, lift cylinders and a PLC controller. Some experimental data of water-hydraulic components were included. Simulation tests were performed to confirm a series of press operations. The simulated results were compared with results obtained from an experimental water-hydraulic molding press. Simulated results showed good agreement with the experimental results.
