What is the noise when the hybrid injection molding machine is working?

Dec 04, 2019

The noise produced by the hybrid injection molding machine at work often indicates that the machine has parts damaged or that some of the workers made improper adjustments. We can investigate the cause of the noise and repair it in a timely manner.

    Cause one: The hydraulic fluid is insufficient. It should be known that if there is not enough hydraulic oil in the oil tank of the hybrid electric injection molding machine, the oil pump can easily absorb the outside air or it can easily absorb some dirt to block the oil pump. The lack of oil is more serious, and the air bubbles in the oil will also have an impact on the blades, and noise will naturally occur. How to solve this situation? We need to check the amount of oil to avoid the entry of air and dirt.

    Reason two: high viscosity. The viscosity referred to here is actually hydraulic oil. If the viscosity of the hydraulic oil is high, the resistance caused by the flow is also relatively large, so based on this situation, our staff needs to periodically check and replace the hydraulic oil in time.

    Cause three: When the hybrid injection molding machine is operating, if noise is generated, it is likely to be caused by damaged motor blades or damaged parts such as oil pump bearings. Under the influence of the deviation of the concentricity, the noise will naturally occur produced. This requires staff to check concentricity or replace parts.

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