Electrical Power	As per your requirement

1.To start machine by two hand buttons,time relay controls machine's return stroke. 2.Connected to power, in the "manual" state,operator can make machine do low force inching rise or inching drop 3.action by pressing inching rise or inching drop buttons,so as to correct moulds. 4.In the "automatic" state, machine will start after operator put workpiece on work bed and press switches by two hands.during fast approach stroke, the upper moulds move to workpiece quickly and gently with low-noise, no impact, when upper moulds contact with workpiece machine will build up full power(power stroke) automatically from fast low force approach stroke until set-up time over,then time relay controls moulds returning automatically,so as to insure machine builds up enough pressing force required. 5.Speed of Fast approach stroke and returning stroke can be adjusted stepless, so as to meet different working frequency requirement. 6.Machine's maintenance system can process inlet compressed air so as to make it gas-water seperated and oil atomization, you can also adjust the pressure of inlet air source stepless, so that machine's output force is adjustable stepless. 7.With an emergency returning button, moulds can return immediately anytime. 8.There is a power stroke regulating valve, which can adjust pressing force of power stroke while machine's speed is not changed, in this way it can protect moulds and energy-saving.
