Develop Good Habits of Injection Molding Machine Operation

Cultivating good operation habits of injection molding machines is of great benefit to improving machine life and production safety.


1. Before startup:


(1) Check whether there is water and oil in the electrical control box. If the electrical appliance is damp, do not start the machine. The maintenance personnel shall blow dry the electrical parts before starting the machine.


(2) Check whether the power supply voltage conforms to the standard, which shall not exceed ± 15% generally.


(3) Check whether the emergency stop switch and front and rear safety door switches are normal. Verify whether the rotation direction of motor and oil pump is consistent.


(4) Check whether all cooling pipes are unblocked, and feed cooling water into the oil cooler and the cooling water jacket at the end of the barrel.


(5) Check whether there is lubricating oil (grease) at all moving parts, and add enough lubricating oil.


(6) Turn on the electric heating to heat up each section of the barrel. When the temperature of each section meets the requirements, keep it warm for a period of time to stabilize the machine temperature. The heat preservation time varies according to the requirements of different equipment and plastic raw materials.


(7) Add enough plastic in the hopper. According to the requirements of different plastics for injection molding, some raw materials should be dried first.


(8) The heat shield on the machine barrel shall be covered, which can save electric energy and prolong the life of the electric heating coil and the current contactor.


2. During operation:


(1) Do not cancel the function of the safety door for convenience.


(2) Pay attention to the temperature of the pressure oil, and the oil temperature shall not exceed the specified range. The ideal working temperature of hydraulic oil should be kept between 45~50 , generally within the range of 35~60 .


(3) Pay attention to the adjustment of each travel limit switch to avoid the impact of the machine during operation.


3. At the end of the work:


(1) Before shutdown, the plastic in the barrel shall be cleaned to prevent the residual material from oxidation or long-term thermal decomposition.


(2) The mold shall be opened to keep the toggle mechanism locked for a long time.


(3) The workshop must be equipped with lifting equipment. Be very careful when assembling and disassembling heavy parts such as molds to ensure production safety.
