Develop good habits to improve the operation of injection molding machine plant life and safety are good.

 First, before you start:

    (1) Check the electrical control box if there is water, oil enters, if appliances damp, do not boot. Maintenance personnel should be dry before turning the electrical parts.

    (2) Check whether the supply voltage, generally should not exceed ± 15%.

    (3) Check the emergency stop switch, front and rear safety door switch is normal. Rotational direction of the motor and the pump verify whether the same.

    (4) Check the cooling pipe is smooth, and the cooling water jacket and barrel oil cooler ends of the pass into the cooling water.

    If (5) Check all moving parts have lubricant (grease), and add a little oil.

    (6) open electric, for each segment barrel for heating. When the temperature of each section to meet the requirements, and then incubated for some time to stabilize the temperature of the machine. Holding time according to the requirements of different devices and plastic materials vary.

    (7) in the hopper enough to add a little plastic. According to the requirements of different plastics injection molding, it is best to go through some of the raw material drying.

    (8) the heat shield on the barrel to cover, so you can save energy, but also can extend the electric lap and contactors life.

Second, during the operation:

    (1) Do not for the sake of convenience, free to cancel the effect of the security doors.

    (2) to observe the temperature of the oil pressure, oil temperature must not exceed the specified range. The ideal operating temperature of hydraulic oil should be kept between 45 ~ 50 ℃, generally in the range of 35 ~ 60 ℃ appropriate.

    (3) Note that adjust the travel limit switch, to avoid collision in the machine-generated action.

Third, the end of the work:

    (1) before the shutdown, plastic barrel should be cleaned to prevent oxidation or leftover material thermal decomposition of long-term

    (2) shall mold opens, so long toggle mechanism in the locked state.

    (3) workshop lifting equipment must be available. Assembly and disassembly mold and other heavy components should be very careful to ensure production safety.
