It is a key component that prolongs the life of the injection molding machine and one of the biggest factors. Just like your kidney, the filter element keeps the circulating fluid free from particle contamination, which means your valves, pumps and hydraulic components will work normally. Due to the importance of filter elements, you should ensure that they are part of regular maintenance inspections and ensure that they are replaced immediately if they fail.
There are pressure switch indicator lights on the filter, these indicator lights are electrical signals, which will trigger an alarm. When this happens, the system will go wrong. Other signs of full filter elements are degraded valve performance, clamp or pump failure. This alert not only provides valuable information about the filter, but also provides information about possible problems with other parts of the injection molding machine (especially the new machine). Take out the filter and see that it is full of brass, steel, or some other particles. This is a reliable sign that the machine is malfunctioning. Some customers mute the alarm during the production process to avoid audible alarms. So customers with silent alarms will always encounter valve problems, cylinder problems, etc. Ignoring the alarm may keep your injection molding machine running, but it can only run for a while. Ultimately, your injection molding machine must be prepared for a long-term shutdown.
Although this depends on the quality of the oil and the usage of the injection molding machine, the filter should be replaced at least every three months. You may want to clean the filter to extend its life, but like avoiding an alarm, this will only keep you running temporarily. Finally, you still have to replace it. Once the alarm sounds, replace the filter element to avoid compromising the integrity of the filter, making other particles more likely to contaminate your machine and cause long-term downtime.
