Super Ion Air Knives Remove Static, Improve Bottle Cap Production

The leaves have all fallen. The sky, more often than not, is dreary. My winter coat is officially part of the “uniform of the day”. And I got shocked by the laundry room doorknob yesterday. All this means that winter is upon us (here in the Northern Hemisphere anyway), and as far as EXAIR is concerned, it’s “static season”. We’re seeing a definite uptick in the numbers of conversations we’re having about static charge-related issues…and solutions that we can provide.

I had the pleasure of speaking to a caller, last month, who works for the US division of a global manufacturer of bottle caps. A machine that sorts & orients plastic caps was particularly prone to static charge problems last winter, causing a marked decrease in their production, and they wanted to get out in front of the problem this year:

As the caps travel horizontally (white arrows), they pass under a static bar (supplied by the machine manufacturer) which provided some reduction in static charge, but was unable to keep up with the higher magnitudes of static charge experienced during the lower humidity winter months. Bottle caps (right) would pile up, slowing production.
A Model 112230 30″ Gen4 Super Ion Air Knife Kit replaced the OEM static bar, resulting in dramatic improvement…no more piling up of bottle caps.

The increased static charge (beyond the OEM static bar’s ability to handle) reduced production by 1/3. The Super Ion Air Knife restored operation to full capacity for this machine…and three others, once they saw the results of the first one.

If static charge is causing you problems with dust clinging to your product, your product clinging to itself, sheets mis-feeding, materials jamming, tearing, or curling, or nuisance shocks to operators, EXAIR has a variety of safe and efficient Static Eliminator solutions. To find out more, give me a call.
