Summer Injection Molding Machine Maintenance Guide: Confronting the Challenges of High Temperatures

The scorching heat of summer makes one feel as if they are in a steam sauna. Amidst the sweltering weather, amidst various ways to cool off and seek respite, please do not forget to conduct regular maintenance for our PET preform injection molding machine, ensuring its smooth operation.

Key Points for High-temperature Maintenance of PET Preform Injection Molding Machine:

1. Keep the machine and its surrounding environment clean and tidy

Maintaining cleanliness is crucial when operating the machine. Regularly cleaning the electrical box and removing accumulated debris provide optimal heat dissipation and ventilation conditions for the electrical components.

2. Pay attention to electrical safety

In hot weather, warehouses often require the use of numerous fans to cool down. During this time, it is important to ensure the safety of sockets and electrical wiring. Electrical safety within the control box is also paramount. It is strictly prohibited to improperly connect wires, and every six months, wire terminal connections must be tightened to prevent electrical fires caused by circuit overload or short-circuit incidents.

3. Monitor hydraulic oil temperature

Maintaining the working temperature of hydraulic oil between 30 and 50 degrees Celsius is ideal. The temperature of the hydraulic oil directly affects other components in the system, such as the oil pump, cylinders, and hydraulic valves, thereby reducing control precision and responsiveness. Excessive temperature can also accelerate seal aging and damage hydraulic components. Therefore, in high ambient temperatures, the injection molding machine should have its cooling system activated prior to start-up to prevent the oil from sustaining damage due to excessive heat.

4. Ensure the normal operation of the cooling system

Regularly inspect the cooling system of the injection molding machine to ensure its proper functioning and ensure unobstructed flow in the cooling water pipes. If the quality of water is poor, frequent cleaning is necessary, as failure to do so may result in high machine temperatures and malfunctions.

5. Be cautious of summer rain and typhoon weather

Summer is not only characterized by high temperatures but also frequent rain showers and typhoons. It is essential to inspect the drainage systems both inside and outside the factory in advance. If the machine is submerged in water, the hydraulic system must be cleaned, and the hydraulic oil replaced. Lubrication, cleaning, and oil replacement should be conducted for mechanical moving parts, along with rust prevention and anti-corrosion measures. In the event of water immersion in the circuit board, the start-up operation should only be performed after storing the board in a sealed box with a desiccant for 72 hours, ensuring complete drying.

Summer maintenance is crucial for PET preform injection molding machines. To extend the lifespan of your equipment, please remember to regularly inspect, maintain, and service your injection molding machine to ensure its smooth operation.
