The powder forming four column hydraulic press is economical and practical. The hydraulic control adopts the integrated system of plug-in setting valve to reduce the discharge point. It has reliable movement, durability and long service life. The first is the constant pressure realization and the secondary development technology of constant pressure program, which has the function of ensuring the differential pressure delay. The stroke of working pressure can be adjusted within the specified range. The centralized control of buttons can realize manual There are three operation forms: semi-automatic and automatic.
