The Injection Molding Machine Has Been Shut Down for A Long Time, What Issues Need To Be Paid Attention To before Starting It Up?

1. Turn on the main power switch of the machine tool, check whether the equipment is leaking, and preheat the barrel and mold according to the set process temperature requirements. When the barrel temperature reaches the process temperature, it must be kept warm for more than 20 minutes to ensure that the temperature of each part of the barrel is Evenly.

2. Open the cooling water valve of the oil cooler, cool the oil return and water transport pipes, and start the oil pump. If no abnormality is found, the oil pump can be officially started. Only after "Motor On" is displayed on the screen, can the oil pump be operated. Pay attention to the motor. Reverse and check whether the safety door is functioning properly.

3. Manually start the screw rotation and check whether the screw rotation sound is abnormal or stuck.

4. The operator must use a safety door. If the safety door travel switch fails, the machine is not allowed to be started. Operation without a safety door (cover) is strictly prohibited.

5. The various covers and protective covers of the electrical, hydraulic and rotating parts of the operating equipment must be covered and fixed.

6. No one other than the operator on duty is allowed to press buttons or handles without permission, and two or more people are not allowed to operate the same injection molding machine at the same time.

7. Place the mold and inserts stably and reliably. If any abnormality is found during the mold closing process, stop the machine immediately and notify technicians to troubleshoot.

8. When the machine is repaired or the mold is cleaned for a long time (more than 10 minutes), the injection seat must be moved back to make the nozzle leave the mold, and the motor is turned off. When the maintenance personnel repair the machine, the operator is not allowed to leave the job.

9. No one is allowed to start the motor when someone is handling the machine or mold.

10. When the body enters the machine tool or the mold opening, the power supply must be cut off.

11. Avoid hitting the fixed mold with the injection seat when the mold is open to prevent the fixed mold from falling off.

12. The air injection generally does not exceed 5 seconds each time. When the injection fails twice in a row, please notify nearby personnel to avoid the danger zone. When cleaning the nozzle rubber head, do not clean it directly with your hands. Use iron pliers or other tools to avoid burns.

13. The melt barrel is exposed to high temperature, high voltage and high electricity during operation. It is prohibited to step on, climb or place objects on the melt barrel to prevent injury, electric shock and fire.

14. When the hopper is not loading, it is not allowed to use metal rods or rods to poke the hopper roughly to avoid damaging the split screen, screen shield and magnet frame in the hopper. If the screw is rotating, the metal rod is easily involved in the machine. Equipment accident causing serious damage to the barrel.

15. If the injection molding machine is found to have abnormal noise, odor, sparks, oil leakage or other abnormal conditions during operation, it should be stopped immediately, report to the relevant personnel immediately, and explain the fault phenomenon and possible causes.
