Five hazards of high temperature in injection molding machines: mechanical thermal deformation, reduced oil viscosity, rubber seal deformation, accelerated oil oxidation, and decreased air pressure.

Mechanical deformation

Hydraulic components, with varying thermal expansion coefficients for moving parts due to their smaller and sensitized nature, can affect the transmission accuracy of hydraulic systems, leading to poor-quality parts.

Reduce oil viscosity

Excessive temperature rise in injection molding machines can lead to oil leakage, increased viscosity, and a reduction in the volumetric efficiency of pumps, significantly lowering the overall system efficiency. Due to the reduced oil viscosity and the thinning of the oil film on moving parts' valves, which is cut off, friction resistance increases, resulting in increased wear.

III: Rubber Seal Deformation

Overheating of injection molding machines can deform rubber seals, accelerate aging and failure, reduce sealing performance and lifespan, leading to leakage.

Four: Oil oxidation and injection molding machine temperature accelerated oxidation

High temperatures accelerate oil oxidation and degradation, settle asphalt materials, and reduce the lifespan of hydraulic oil. Sediment clogs damping holes and narrow valve orifices, rendering pressure valves inoperable, and leads to metal pipe extension, bending, and even fractures.

Five: Poor quality injection molding machine

Overheating in injection molding machines can lead to poor part quality, the release of dissolved air, oil/gas corrosion, and a decrease in the performance of the hydraulic system.
