Plastic mold manufacturers share that the temperature during mold production and injection molding has a significant impact on the quality of the molding
Time: September 22, 2024
Temperature degree is one of the key factors affecting the quality of injection molding, and its level directly affects the quality and molding effect of the mold.
During the production and processing of plastic molds by plastic mold manufacturers, excessive temperature can cause a series of problems.
1. The machine may undergo thermal deformation due to small fit, operational failure, or jamming of moving parts with different thermal expansion coefficients in hydraulic components, which can affect the transmission accuracy of the hydraulic system and reduce the working quality of the components.
2. Excessive temperature can cause a decrease in oil viscosity, increase leakage, and reduce the efficiency of the entire system and the volumetric efficiency of the pump. In addition, a decrease in oil viscosity can increase frictional resistance, leading to increased component wear. In addition, excessive temperature can also cause sealing deformation, leading to deformation of the workpiece, reducing sealing performance, and ultimately shortening the service life.
3. Excessive temperature will accelerate the deterioration of the oil and reduce its lifespan.
4. Excessive temperature can lead to the deterioration of the quality of working components, the escape of air dissolved in the oil, the formation of cavitation, and the reduction of hydraulic system performance. Therefore, reasonable control of the temperature of the injection molding machine is an important measure to ensure the quality of injection molding.
