What work must the injection molding machine do before injection molding?

writer:LI SONG Share

Before starting the injection molding machine, it is necessary to conduct a preliminary inspection of the injection molding machine to check whether various safety devices are effective, and whether each travel switch is normal, check the amount of lubricating oil, and lubricate the injection molding machine.

What must be done before the injection molding machine is started?
① Check whether there is water or oil in the electrical control box. If the electrical components are damp, do not start the machine. The electrical components should be blown dry by maintenance personnel before starting the machine.
② Check whether the power supply voltage meets the requirements, generally should not exceed 15%.
③ Check whether the emergency stop switch and front and rear safety door switches are normal. Verify that the rotation direction of the motor and the oil pump are the same. Check whether the electrical connections are loose.
④ Check whether the cooling pipes are unobstructed, and pass 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) in each movable part, and add enough lubricating oil.
⑥ Turn on the electric heating switch to heat each section of the barrel. When the temperature of each section reaches the requirements, keep it warm for a period of time to stabilize the temperature of the injection molding machine. The holding time varies according to the requirements of different equipment and plastic materials.
⑦ Put enough plastic in the hopper. According to the requirements of different plastics for injection molding, some raw materials need to be dried first.
⑧ The heat shield on the barrel should be covered, which can not only save energy, but also extend the life of the electric heating coil and current contactor.

The above is the preparation work that LISONG Machinery will introduce to you before starting the injection molding machine and before injection molding, so that users can better understand, use and maintain the injection molding machine, and develop good injection molding operation habits to improve the life of the injection molding machine and production safety. Both are very good.If you want to kown more about injection molding machine price,please leave message to us!email:kevin@lisonginc.com
