Know that injection molding machine "temperature rise is too high" there are a few harm it?

Updated: 2016-10-26

First, the injection molding machine temperature rise is too high (five comprehensive analysis of hazards):

   Injection molding machine is the largest use of plastic processing machinery, not only a large number of products available directly to the production of injection molding machine, but also the key components of injection-blown blowing process equipment, injection molding process, many enterprises will find injection molding machine temperature rise Is too high, and this is actually on the injection molding machine equipment is a great harm.

Which will be several hazards? (Down to see to know)

1. Lead to rubber seal shape change, too high temperature of the injection molding machine will lead to deformation of the rubber seal, speed up the failure of aging, reducing sealing performance and lead to the use of time, causing leakage.

2. Reduce the quality of component work, the injection molding machine temperature rise too high will lead to lower component quality, oil dissolved air escape, cavitation, resulting in lower hydraulic system performance.

3. The thermal deformation caused by mechanical, hydraulic components of the thermal expansion coefficient of the movement of the components because of their smaller and stuck with the probationary, causing action failure, affecting the hydraulic system transmission accuracy, resulting in deterioration of component quality.

4. The viscosity of the oil decreases and the temperature of the injection molding machine is too high. The viscosity of the oil decreases and the leakage becomes large. The volumetric efficiency of the pump and the efficiency of the whole system will decrease obviously. The film side thin and was cut, increased friction resistance, resulting in increased wear and tear.

5. To speed up the deterioration of the oil oxidation, injection molding machine temperature rise is too high will accelerate the oxidation of oil deterioration, precipitation of asphalt material, reducing the lead time of hydraulic oil, precipitate blocked damping holes and slot valve, resulting in pressure valve card Dead and can not move, the metal pipe elongation and bending, and even rupture.

The above characteristics are too high temperature damage.
