How Important Is The Filter To The Injection Molding Machine?

Jul. 27, 2020

The filter is one of the most critical components on the Injection Rubber Machine. It is a key component to prolong the life of the machine and one of the biggest factors. Just like your kidney, the filter element keeps the circulating fluid free from contamination and particles, 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. In this article, the Injection Molding Machine Manufacturers will discuss the signs that your filter is malfunctioning and how often you should change the filter.

How do I know if the filter needs to be replaced? There are pressure switch indicator lights on the filter, these indicator lights are electrical signals, it will trigger an alarm. When this happens, the system will go wrong. Other signs of full filter elements are valve performance degradation, clamp or pump failure. This alert not only provides valuable information about the filter, but also provides valuable information about possible problems with other parts of the machine (especially new machines). We have asked customers to stop their machine before taking out the filter, and we have seen it full of brass, steel, or some other particles. This is a reliable sign that the machine is malfunctioning. If you can mute the alarm during the production process, we do see customers doing this to bypass the sound alarm. Not surprisingly, customers who decide to bypass the alarm will also encounter valve problems, cylinder problems, etc. Ignoring the alarm may keep you running, but only that long. Ultimately, it will prepare you and your operations for long-term downtime.


In short, the filter is one of the most critical components on the Vertical Plastic Injection Moulding Machine. It is a key component that prolongs the life of the machine and one of the biggest factors. We should ensure that they are part of regular maintenance and inspections, and ensure that they are replaced immediately when the filter element fails.
