In the process of plastic injection molding, the temperature is too high or too low, will have an adverse effect on the molded injection molding products, and seriously affect the abandonment of the molded injection molding products. Therefore, temperature control during injection molding is very important.
The injection molding process requires the use of plastic raw materials, toner, nozzle materials, molds, injection molding machines, peripheral equipment, installation fixtures, sprayer, various auxiliary materials and packaging materials, etc., which brings a lot of workload and certain difficulty to the management of the injection molding plant, compared with other industries or departments, higher requirements for managers at all levels of the injection molding plant.
The injection molding process temperature is too high may reduce the viscosity of the oil, increase leakage, and the volumetric efficiency of the pump and the overall efficiency of the system will also be significantly reduced. When the viscosity of the valve column decreases, the oil film of the working parts such as the valve column becomes thinner or the bevel is cut off. At this time, the friction resistance is also increased, and the wear is also increased.
What is the bad effect of too high temperature on injection molding?
If the injection molding process temperature is too high, the working quality of the injection parts will deteriorate, and the air dissolved in the oil will be discharged, resulting in cavitation, thereby reducing the working performance of the hydraulic system.
The parts with different thermal expansion coefficients in the hydraulic components must become smaller with the apprentice, so the main engine is blocked, causing work failures, seriously affecting the transmission accuracy of the hydraulic system, resulting in poor working quality of the parts processed by injection molding.
The temperature rise of injection molding process is too high, which will promote the oxidation deterioration of oil, analyze the material of asphalt, and reduce the life of hydraulic oil. In addition, the analyzed substance may clog the buffer holes and gap ports, causing the pressure valve to become clogged and not work, and the metal line may extend and bend or break.
