If so, you can provide enormous savings to a company by implementing a Preventive Maintenance program on your packaging lines. Provided is a sample of a simple PM Check List for preventive maintenance on the adhesive melting equipment that can get you started.  Start small and move up to the whole packaging machine.  You can be the hero and provide a longer life for the company's machinery, save in spend in parts purchased and prevent expensive downtime. Some of the many ways to extend the life of the adhesive melter are: Change filters before contaminants cause restricted flow (both tank and and inline) Purge tank of contaminants  (Keystone provides cleaner) Replace seals/gaskets in pump Check glue hoses for wear/tear Check circuitry for accurate settings (Keystone repairs OEM circuit boards) Verify applicators and hoses are holding set temperatures Clean or replace nozzles Verify glue modules are not leaking and are firing properly Verify tank manifold has no leaks Verify pump is shifting correctly and holding pressure Need more info or assistance with parts?

When it comes to protecting your hot melt equipment, Keystone Industries® is clued in to the most effective maintenance schedules. Using a Nordson®-compatible filter is essential to preventing char and other contaminants from gumming up the works. Clogs are a nasty, time-consuming problem to solve, so before you forget to change your filters, consider what the downtime will really mean to your business. It's worth the time and expense to change them on a regular basis. Fortunately, with our inline filters, it's also faster and more affordable!
