What is the effect of temperature on injection molding

Many people know that injection molding is a very important step in processing a mold, and temperature is the top priority, because the temperature affects the quality of the mold during injection molding. What will be the impact of this temperature?

So what are the disadvantages 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 coordination 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. Oil viscosity reduction: if the temperature of the injection molding machine is too high, the viscosity of the oil decreases and the leakage increases, 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 the movable parts of the valve core increases, resulting in increased wear.

3. Sealing deformation: if the temperature of the injection molding machine is high, it is easy to deform the workpiece, so as to reduce the sealing performance and reduce the service life.

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

5. Deterioration of the quality of working parts: the temperature of the injection molding machine will cause excessive deterioration of the quality of working components, dissolve in oil, escape air and cavitation, resulting in the reduction of the performance of the hydraulic system.
