Maintenance Guide | Precautions for Spring Festival Shutdown of Injection Molding Machines
Date: 2024-02-02Read: 54
Dear customer friends, thank you for your continuous support and trust! The Spring Festival holiday is coming soon. In order to ensure that your injection molding machine can maintain the best production status and normal operation after the holiday, we specially provide the following precautions for shutdown maintenance. We hope it will be helpful to you and help you start production smoothly!
Precautions for shutdown of injection molding machine
01 Mold Protection·
Before stopping the machine, please make sure to perform the following tasks: opening the mold and opening the brake, cleaning the material cylinder, taking care of the mold, and finally lubricating the moving plate, especially.
Spray anti rust agent on the mold and then close it to the fitting position at low pressure. Please ensure that the mold is not in a high-pressure state. Open the mold 5-10MM away from the empty mold to keep the joint in a semi straight state.
If the downtime exceeds 10 days, it is recommended to remove the mold to reduce the load on the moving plate.
02 Material drum cleaning·
If your injection molding machine produces heat sensitive plastics such as POM and PVC, please clean them again with PP material after cleaning.
For injection molding machines producing white or transparent products, after cleaning the production material in the barrel, use PP material for cleaning and set the insulation to 100 ℃. Only when the actual temperature reaches 100 ℃ can the electric heating or main power be turned off.
03 Sanitary cleaning·
When performing hygiene cleaning, please use a powerful air gun to clean the cooling water circuit of the mold.
When cleaning the dust inside the electrical box, be sure to turn off the main power of the machine, remove the air inlet filter, and use a vacuum cleaner to clean from top to bottom.
When cleaning the rack, it should be done from the direction of the shooting platform towards the direction of the locking mold or the direction of the computer operation surface to avoid damaging the cooler water pipes. In addition, corrosive liquids should not be used when cleaning the sheet metal surface to avoid damaging the sheet metal paint.
04 Anti freezing measures·
Turn off the cooling tower, water pump, chiller, and mold cooling system, and cut off the water source for the injection molding machine and auxiliary equipment.
Remove the cooling water outlet pipe from the non operating side of the injection molding machine and drain the water inside the pipe.
After turning off the water source, remove the inlet and outlet connections, drain the water from the cooling element, and use high-pressure air to blow out all residual moisture inside the cooling element.
05 Turn off the power·
Ensure that auxiliary equipment such as robotic arms, hot runners, and sequence valves are reset and in the closed state.
Turn off the electric heating and motor switches, then turn off the machine power and main power, and clean the machine and workplace. After the injection molding machine is stopped, please place rat poison in the corners of the injection molding workshop and at the inlet to prevent damage to the circuit caused by rats.
