Why? Small injection molding machine Noise during operation? The noise made by the injection molding machine during operation often means that the parts of the machine are damaged or the operator makes improper adjustment. In case of noise, the cause must be found out and repaired in time.

1： Insufficient hydraulic oil; When the working oil in the oil tank of the small injection molding machine is insufficient, the oil pump is easy to absorb the external air or dirt under the working state, and the oil pump is blocked. This is the same as adding oil to the fire. The oil is insufficient, and the bubbles in the oil are on the blades. How to solve this problem? It is necessary to check the amount of oil to avoid the entry of air and dirt.

2： High viscosity; The viscosity mentioned here is actually mainly hydraulic oil. The higher the viscosity of the hydraulic oil, the greater the resistance in the flow. Therefore, according to this situation, our staff needs to regularly test the hydraulic oil and replace it in time.

3： When noise occurs during the operation of small injection molding machine, it is likely to be caused by motor blade damage, oil pump bearing damage, etc., which will naturally generate noise due to concentricity deviation. Therefore, operators need to check concentricity or replace parts.

If the above points are eliminated rather than the main cause of noise, we should consider whether the filter element is blocked or worn, and also ensure that the working current is sufficient and stable, otherwise noise will occur.
