What are the hazards of excessive temperature rise of injection molding machine?

Excessive temperature rise of injection molding machine will lead to reduced oil viscosity, increased leakage, and significantly reduced volumetric efficiency of pump and efficiency of the entire system. Due to the reduced oil viscosity, the oil film of moving parts such as sliding valves becomes thinner and cut, the friction resistance increases, and the wear is aggravated. This will shorten the service life of the machine.

Excessive temperature rise of injection molding machine will lead to poor working quality of parts: Excessive temperature rise of injection molding machine will lead to poor working quality of parts, dissolved air in oil will escape, cavitation will occur, and the working performance of hydraulic system will be reduced. At the same time, it will also reduce working efficiency.

Excessive temperature rise of injection molding machine will accelerate the oxidation and deterioration of oil, precipitate asphalt substances, and reduce the service life of hydraulic oil. The precipitate blocks the damping holes and the slit valve port, causing the pressure valve to be stuck and unable to move, the metal pipeline to stretch and bend, and even rupture.
