Why does the injection molding machine produce noise when it is working?

TIME:2021-04-27 Share

Recently, many injection molding machine manufacturers consult Lisong Machinery: Why does the injection molding machine produce noise when it is working?

1. Insufficient hydraulic oil:
It should be known that if there is not enough hydraulic oil in the oil tank of the injection molding machine, the oil pump can easily absorb outside air under working conditions, or it is easy to absorb some dirt to cause the oil pump to block. The situation is more serious, and the air bubbles in the oil will have an impact on the blades, and noise will naturally be generated.
How to solve this situation? We need to check the amount of oil to avoid the ingress of air and dirt.

2. High viscosity:
The viscosity referred to here is actually hydraulic oil. If the viscosity of the hydraulic oil is high, the resistance brought by the flow process is also relatively large, so based on this situation, our staff need to check regularly and replace the hydraulic oil in time.

3. When the injection molding machine is working, if noise is generated, it is likely to be caused by damage to the motor blades, or damage to the oil pump bearings and other parts. Under the influence of the deviation of concentricity, the noise will naturally occur. This requires staff to check the concentricity or replace parts.

If the above points are eliminated and not the main cause of noise, then we should consider whether the filter element is clogged or worn, and at the same time, we should ensure that the working current is sufficient and stable, otherwise noise will occur.
