1. Check the electrical control cabinet for water and oil before operating the injection molding machine. Do not start the machine if the cabinet is wet. Maintenance personnel should blow the electrical components dry and then turn on the machine.

2. Before operating the injection molding machine, check that the supply voltage is appropriate, usually should not exceed ± 6%.

3. Check the emergency switch and check whether the front and rear safety door switches are normal. Check that the motor is rotating in the same direction as the oil pump.

4. Check that each cooling tube is smooth and add cooling water to the oil cooler and the cooling water cover at the barrel end.

5. Before operating the injection molding machine, check all moving parts of the machine for lubricating oil and add enough lubricating oil.

6. Turn on the heater switch and heat all parts of the barrel. When the temperature of each section reaches the requirement, keep it for a period of time to make the machine temperature stabilize. The holding time varies according to the different requirements of the equipment and plastic raw materials.

7. Add enough plastic to the hopper. Some raw materials should be dried first according to the different requirements of injection molding.

8. Cover the heat shield of the barrel to save power and extend the listening life and contactor life.

In the process of injection molding machine operation

1. Do not cancel the role of the security door.

2. Pay attention to check the temperature of the pressure oil. The oil temperature should not exceed the specified range. The working temperature of the lubricating oil should be kept between 45-50 °C, and the range of 35-60 °C is suitable.

3. Pay attention to adjust the travel switch to avoid the impact of the machine when the machine is running.

Operation of the injection molding machine after the machine is running

1. After the operation of the injection molding machine is completed, the plastic in the barrel is cleaned to avoid oxidation of the material and long-term thermal decomposition.

2. The mold should be opened to lock the toggle mechanism.

3. The workshop should have lifting links and carefully disassemble the mold to ensure production safety.
