What is the hazard of excessive temperature generated by the injection molding machine?

The injection molding machine needs to effectively control the temperature when it is operating. Even advanced injection molding machines need to pay attention to this problem. Because when the temperature of the injection molding machine increases, the quality of the parts of the injection molding machine will become poor. The effect at this time is that the air dissolved in the oil will be reduced, which will cause cavitation. As a result, the performance of the hydraulic system will have a low effect when it is working. The temperature of the injection molding machine needs to be adjusted to between 45 and 50 degrees. The main reason is that the hydraulic system can be designed according to a certain pressure oil viscosity, but this viscosity will change with the change of the oil temperature. It will have a bad effect on the working components in the system, which will lead to a decrease in the sensitivity of the control accuracy and response, especially for precision instruments, this phenomenon will be more serious. Therefore, when using the injection molding machine, it is necessary to prevent the temperature of the injection molding machine from being too high, because if the temperature of the injection molding machine is too high, it will cause greater harm. 1. Excessive temperature of the injection molding machine will cause mechanical deformation due to heat, and its moving parts will become stuck due to the smaller gap between them, which will lead to poor work quality. 2. If the temperature of the injection molding machine is too high, the viscosity of the oil will decrease and leakage will occur. Because the viscosity of the oil decreases and the lubrication effect becomes worse, its frictional resistance will increase, which will lead to aggravation of friction. 3. If the temperature of the injection molding machine is too high, the rubber seal will be deformed. After the deformation, it will accelerate the aging, which will reduce the characteristics of the seal and the service life, and cause the leakage of the medium. 4. If the temperature of the injection molding machine is too high, it will accelerate the deterioration of the oil due to oxidation. This precipitate will block the small holes and the valve, causing the valve to be stuck and unable to perform normal work.
