Processing in high temperature injection molding machine may be about to happen
(1) the mechanical thermal deformation, thermal expansion coefficient of hydraulic components in the different moving parts because the gap is smaller and stuck, causing action failure, the impact of the hydraulic system driving accuracy, resulting in deterioration of the quality of parts.
(2) the oil viscosity reduction, increased leakage, the pump's volumetric efficiency and overall system efficiency will be significantly reduced. As the oil viscosity, spool and other moving parts of the film was cut thin and broken, friction increases, resulting in increased wear and tear.
(3) deformation of the rubber seals, accelerated aging failure, reducing the sealing performance and service life, resulting in leakage.
(4) accelerate the oxidative deterioration of oil, and precipitation of asphalt material to reduce the service life of hydraulic oil. Precipitate and plug the holes in the damping gap-type valve port, causing pressure valve card dead can not move, stretch and bend metal piping code, or even rupture.
(5) to reduce the oil pressure of the air separation, oil dissolved air to escape, resulting in cavitation, resulting in the hydraulic system performance.
