What is the influence of temperature during injection molding

As many people know, injection molding is a very important step in processing a mold, and temperature is the most important, because the temperature affects the quality of the mold during injection molding. What will the temperature affect?

So, what is the disadvantage of high injection processing temperature? How do we deal with the problem of excessive temperature? Now let’s take a brief look.

1. Thermal deformation of the machine: due to small cooperation and operation failure, the moving parts with different thermal expansion coefficients in the hydraulic components are stuck, which affects the transmission accuracy of the hydraulic system and reduces the working quality of the parts.

2. The viscosity of the oil decreases: the viscosity of the oil with too high temperature of the injection molding machine decreases, the leakage increases, and the efficiency of the whole system and the volumetric efficiency of the pump will be significantly reduced. As the viscosity of the oil decreases, and the oil film becomes thinner, the friction resistance of movable parts such as the cutting valve core increases, resulting in increased wear.

3. Sealing deformation: if the temperature of the injection molding machine is high, the workpiece is easy to deform, which reduces the sealing performance and then reduces the service life.

4. Deterioration of oil: if the temperature is too high, the oil will accelerate to expire, and there will be asphalt and other substances, and the life of hydraulic oil will be reduced.

5. Deteriorate the quality of the working parts: The temperature of the injection molding machine will cause excessive deterioration of the quality of the working parts, which will release air dissolved in the oil and cause cavitation, thus reducing the performance of the hydraulic system.
