(1) According to the principle of hydraulic transmission, the layout of the actuator (cylinder and plunger or piston) is simple, and it is easy to complete large working pressure, large working space and long working stroke, so it is customary and convenient to restrict large workpieces or long and tall workpieces.

(2) The additional maximum pressure of the press can appear in any direction of the stroke. Many technologies can switch points, so it is necessary to keep the pressure for a long time.

(3) The pressure in an operation cycle can be adjusted or limited by a simple method (various valves), and it is not easy to simply overload and maintain various molds.

(4) The total stroke of the slider can be changed infinitely within a certain range, and the down conversion point of the slider stroke can be controlled or changed according to the pressure or stroke direction.

(5) The slider speed can be adjusted to some extent, and then you can get used to the different requirements of the process flow for the slider speed. When the pump is used for direct transmission, the adjustment of slider speed can be independent of pressure and stroke.

(6) Compared with the punch press, the working board is stable, with less impact, vibration and noise, and the equipment itself has great advantages. First generation mechanical solutions
