Injection molding machine to avoid high temperatures

At the time of the injection molding machine work, sometimes find injection molding machine temperature is too high, this will cause a lot of damage to the injection molding machine, for example: moving element hydraulic components in thermal expansion coefficient differences between the trainee with its smaller and stuck, causing the action failure, affect the accuracy of the hydraulic drive system, resulting in deterioration of the quality of the work element. Injection molding machine temperature is too high will lead to save the oil viscosity decreases, leakage increases, the volumetric efficiency of the pump efficiency and the entire system will be significantly reduced. Because the viscosity of the oil decreases, thin film spool and other mobile elements are cut through, the frictional resistance increases, resulting in increased wear. Injection molding machine temperature is too high will lead to the province's rubber seal deformation, failure to speed up the aging, reduce the sealing performance and lead to the use of time, causing leaks. Injection molding machine temperature rise too high will accelerate oil oxidation deterioration, precipitation of asphalt material, reducing the lead with a time of hydraulic oil. Precipitates clogged pores and crevices damping valve port, causing the pressure valve can not be death card operation, a metal pipe elongation and bending, and even rupture. Injection molding machine temperature rise too high will lead to lower quality of work elements, oil dissolved air to escape, cavitation, causing the hydraulic system lead to reduced work performance.
These injuries summed 5:00: 1 cause mechanical thermal deformation, resulting in oil viscosity decreased 2, 3 lead rubber seal shape change, to accelerate oil oxidation deterioration 4, 5 elements work led to reduced quality....
Therefore, we should try to avoid the injection molding machine in a high-temperature environment over when using.
