The most expensive defects often begin with the smallest maintenance gaps that no one notices until it's too late.

In every type of plastic processing, drying hoppers are essential for maintaining resin moisture levels within specification. However, one often-overlooked issue can compromise the entire drying process: ambient air leaks.

These leaks allow humid, cool air to enter the system, reducing drying efficiency and leading to inconsistent material quality, longer drying times, and potential defects in the final product. Something that none of us want!

Even small leaks can have significant consequences, including increased energy consumption as dryers work harder, higher scrap rates caused by moisture-related defects, and production delays that add unnecessary costs.

Regular inspection of seals, gaskets, and connections is critical to prevent leaks before they impact performance, as is preventive maintenance such as replacing worn components promptly which helps maintain system integrity.

At NS KUNSTSTOFFTECHNIK - CZ we take these proactive measures every single day. What steps are you taking to keep ambient air out of your drying systems, and where do you see the biggest opportunities to tighten up reliability?
