Hydraulic Press for manhole cover

The series of hydraulic press is mainly used for hot forming process of composite material products such as manhole covers. Three-beam four-column structure is designed for the press, and the knock-out device is mounted in the lower beam. Cartridge valve integrated unit equipped in hydraulic control system, with high reliability, durability. Oil leakage is avoided by means of proper piping and minimum hydraulic impact design. By control of centralized button based on PLC, electrical system is durable and easy operated. The adjustment mode and two-hand single cycle mode are available for selecting. According to the requirements, stroke and pressure can be adjusted within specified scope. It can realize the fixed stroke and fixed pressure forming processes. In condition of pressure holding，the motor is only running on the situation of pressure compensation for energy saving. The PID intelligent system is adopted for die temperature controlling, with the accuracy of ±1℃.
