Not computer, there is a proportional current. The whole machine has no hydraulic operation and the pressure gauge is zero.
1, there may be an electromagnetic coil trip switch electric eye in place, did not hit the safety bar, total oil valve inside and the electrical box output meter electric appliance or poor contact.
2 、 injection molding machine, also known as injection molding machine or injection machine. It is a thermoplastic or thermosetting plastic plastic molding mold made of plastic products of all shapes of the main molding equipment. It is divided into vertical, horizontal and all electric type. The injection molding machine heats the plastic, applying high pressure to the molten plastic to make it crack and fill the mold cavity.
Oil pump is good, the current output is good, that is, no pressure, it must be converted from electrical signals to hydraulic parts of the action of the middle course of disconnection, or the overflow valve spool stuck, or the pilot valve of the electromagnetic iron ring broken
