Plastic Injection Molding Machine
Striving for excellence
providing complete injection molding strategy to meet customers' requirements

Offering a complere configuration system,users can choose a suitable plastic injection molding machine in terms of different requirements

Several problems caused by high temperature injection molding machine

  • : Accelerate oil oxidation deterioration:injection molding machine temperature is too high will accelerate the deterioration of the oil oxidation, precipitate bituminous substances, and reduce the service life of the hydraulic oil. Precipitates clog the damping holes and gaps valve port, resulting in pressure valve locked and cannot move, the metal pipe elongation, bending, or even rupture.
  • : Deformation of the rubber seals: injection molding machine temperature rise is too high that will deform the rubber seals, accelerate aging failure, and reduce the airproof performance and service life of the seal, causing leakage.
  • : Reduce component working quality: injection molding machine temperature is too high will reduce component working quality, oil dissolved air to escape, cause air pocket, cause the hydraulic system performance degradation.
  • : To reduce the viscosity of the oil: the temperature rise of the injection molding machine is too high will cause the lower viscosity of the oil, increase in leakage, and will significantly reduce the volumetric efficiency of the pump and the entire system efficiency. Due to lower viscosity of the oil, the slide valve and other moving parts’ oil film will be thinner and broken, the friction increases, resulting in increased wear.
  • : The mechanical will thermal collapse: The moving part of hydraulic components with different Coefficient of thermal expansion will be stuck due to its smaller copulate clearance, Lead to fail to operate, to affect hydraulic system driving accuracy, resulting in the part with poor quality of work.
