Three criteria for choosing hydraulic oil for injection molding machine!

Injection molding machine is a plastic processing process, polymer processing will consume a lot of energy, and a large amount of energy consumption will also be generated in the cooling device, air compression and other links. Such a large energy consumption injection molding machine will naturally require hydraulic oil. Have produced very high standards, so how to choose the hydraulic oil of the injection molding machine? There are three major standards for reference!

One of the criteria for selecting hydraulic oil for injection molding machine: select hydraulic oil with suitable viscosity and temperature. The viscosity requirements of the hydraulic oil at the working  temperature and starting temperature of the injection molding machine are related to the fluidity of the hydraulic action of the injection molding machine and the accuracy of the transmission, which directly affects the working efficiency of the injection molding machine. Therefore, the hydraulic oil selection of the injection molding machine should consider the viscosity and stability. Whether the performance meets the requirements of the production work, if it does not meet the requirements, it should be replaced in time. At the same time, according to different external environmental temperatures, it is also necessary to appropriately select the appropriate hydraulic oil.

The second criterion for selecting hydraulic oil for injection molding machine: anti-wear hydraulic oil. Generally, under high-pressure work, it will increase the friction during work. Therefore, anti-wear hydraulic oil is a hard requirement. It can not only reduce friction on injection molding machines. The damage can also improve work efficiency. At the same time, this hydraulic oil also has anti-rust and anti-oxidation effects. The anti-wear hydraulic oil that is given priority for injection molding machines is generally No. 46 or No. 68.

The third criterion for selecting hydraulic oil for injection molding machine: the shear stability of the hydraulic oil. In the production process, the hydraulic oil will be severely sheared when passing through the micro-holes of the pump and valve. At this time, the performance and effect of the hydraulic oil will be damaged. Therefore, when the hydraulic oil is selected, the resistance to the hydraulic oil is Shearing capacity must have a high-demand selection standard, which has a good protective effect on maintaining the functionality of the injection molding machine.

There are standards for selecting hydraulic oil, and there must be standards during the use of hydraulic oil. Some hydraulic oils have a reduced efficiency after being used for a period of time, so they must be replaced in time. The blackening of the hydraulic oil or the presence of some impurities in the hydraulic oil is to remind us that there has been a problem with the hydraulic oil. We must pay attention to timely supplement and replacement of the hydraulic oil. This is not only for the maintenance of the injection molding machine, but also saves time and electricity. , An effective guarantee for work.
