The temperature rise of the injection molding machine is five major hazards: it causes the machine to produce thermal deformation, the viscosity of the oil decreases, the rubber seal deforms, and the oil accelerates the oxidative deterioration, and at the same time, the component pressure of the air is reduced.
The moving parts with different coefficients of thermal expansion in the hydraulic element are stuck due to their smaller fit clearance, causing malfunctions, affecting the hydraulic system's transmission accuracy, and resulting in poor working quality of the parts.
Hazard II: Reduce the viscosity of the oil
If the temperature of the injection molding machine rises too high, the viscosity of the oil will decrease, the leakage will increase, and the volumetric efficiency of the pump and the efficiency of the entire system will be significantly reduced.
Hazard 3: Deformation of Rubber Seals
Hazard 4: Accelerated oil oxidative deterioration
If the temperature rise of the injection molding machine is too high, it will accelerate the oil oxidative deterioration, precipitate the asphalt material and reduce the service life of the hydraulic oil.
Hazard 5: Lead to poor working quality of parts
