The injection molding temperature of pin connector is too high

In the process of injection molding, the temperature of the pin connector is a very critical factor, and its level will directly affect the quality of the injection molding process.What happens if the injection molding temperature of  pin connector is too high?The introduction of yeahui is as follows.

The Injection molding temperature of  pin connector is too high

First, Thermal deformation of the machine:

The moving parts with different thermal expansion coefficients in the hydraulic components are stuck due to the smaller matching clearance, causing malfunction. It will affect the transmission precision of the hydraulic system, and also affect the working quality of the components.

Second, reduce the viscosity of the oil:

Excessive temperature rise in the injection molding machine will result in lower viscosity of the oil, increased leakage, the volumetric efficiency of the pump and the efficiency of the entire system are significantly reduced. As the viscosity of the oil is lowered, the oil film of the moving parts such as the slide valve is thinned and cut, and the frictional resistance is increased, It will result in an increased wear.

Third, Deform the rubber seal:

In the actual test, it was found that the excessive temperature rise of the injection molding machine would deform the rubber seal, accelerate the aging failure, reduce the sealing performance and service life, and cause leakage.

Fourth, the oxidation and deterioration of the oil:

If the temperature rise of the injection molding machine is too high, it will accelerate the oxidation and deterioration of the oil, precipitate the asphalt material, and reduce the service life of the hydraulic oil. The precipitate blocks the damper orifice and the slit valve port, causing the pressure valve to become stuck and unable to move, the metal pipe to be elongated and bent, or even broken.
