  • The vertical injection molding machine is too hot, how to cool it?

    The reason for the high temperature of the injection molding machine is one. The volume of the fuel tank is too small, the heat dissipation area is insufficient, and the capacity of the cooling device is too small. (1) The fuel supply system of the fixed pump selects the capacity of the oil pump according to the fast forward speed. Under high pressure and heating, most of the excess flow will return from the safety valve. (2) When the discharge circuit in the system is faulty or the discharge circuit is not set, the oil pump cannot discharge. The total flow of the pump is
