Cooling Adhesive

September 15, 2009 — Kirk Edwards

EXAIR’s Spot Cooling Products are commonly used to cool adhesive. This application is cooling an adhesive which is familiar to all of us; it’s that stuff which keeps our staples held together in those handy staple logs.

The staples processed in this application are the heavy duty staples used in an industrial staple gun. These staples are heated to about 200°F which allows an initial piece of tape to be applied to the underside of the staples. The tape melts to the staples and creates the staple log.

After the tape has the staples held together, an adhesive is applied to the top of the staples. The adhesive must be cooled quickly or it will continue to bake. If the adhesive is not cooled it becomes very brittle and dry and does not hold the staple log together. After the adhesive is cooled the tape is removed.

An EXAIR Adjustable Spot Cooler provides the cooling on the adhesive immediately after it is applied. This has prevented the adhesive from breaking down due to excessive heat. And because this manufacturer runs multiple sizes of staples on their production lines, the Adjustable Spot Cooler gives them the flexibility to adjust the temperature and volume of cold air if necessary for larger or smaller staple sizes.

EXAIR will help keep your staples together; you just keep using them for your papers.

Cooling Welded Laminant

September 14, 2009 — japanfalone

EXAIR’s customer quilts two laminates together with ultrasonic welds.  The problem that they were having is the material becomes soft and distorts as it is pulled thorough the machine.

This produced an unsightly product unacceptable to their customer. Having done this application before, I suggested using a model 110012 Super Air Knife to cool the welded area right next to the welding horn. This provided cooling air so that the welded imprint set up quickly. As expected, distortion was eliminated. A side benefit was that they were able to crank up the heat and weld faster, further increasing production.

Super Air Knives Cool Latex Molding Application

September 11, 2009 — ndraker

One of our overseas distributors  had a customer who produces molded latex mattresses for the bed industry. Part of the process involves heating the foam resin once placed into the mold cavity to cure it. The mold is heated to 70°C during this process. Once the mattress has been stripped out of the mold, the mold must be cooled back down to 30°C for handling reasons.

Currently, the customer separates the mold halves and puts them into a cooling chamber for 20 minutes to get the temperature to desired level. The customer has problems with separating the mold halves due to worker injury. They also would like to cool the mold halves down more quickly than the 20 minutes they have been living with. So, the customer implemented (4) Model 110012 12″ Aluminum Super Air Knives into the cooling chamber. In this way, they can simply space the top half of the mold up with some wood blocks to allow airflow to access the inside of the mold. The Super Air Knives will now blow into the inside of the mold cavity to produce a convective flow of air to circulate the cold air into the areas that really need it most.  The cooling time was reduced to 10 minutes which is in line with what the customer’s original goal was for cutting cooling time and make for safer handling in the process.

Stay Set Ion Air Jet Helps Separate Cards

September 10, 2009 — esmortimer

You know those plastic gift cards that almost every major retailer, and many smaller retailers, have changed over to?  Well, they are very easy to slide into and out of our wallets.  But, they don’t slide so easily into and out of the feeders used in their manufacturing process.

Case in point, one of these manufacturing companies called me last week looking for a way to help separate the stacks of cards as they are put in to a feeder, one at a time.  Currently, the feeder was getting two or more cards at a time, or sometimes no cards at all, because static electricity was causing the cards to stick together.  Just pulling on the top card was not enough to remove only that top card.

So, I recommended our Stay Set Ion Air Jet.  It will provide a blast of ionized air to help initiate the separation of the top card from the rest of the stack.  It will also eliminate the static electricity on the mating surfaces of the cards, that was preventing the cards from separating.  The magnetic base and stay set hose will allow for precise, yet adjustable, mounting of the assembly so the air stream can be aimed at just the right angle, and fit inside the tight space of the machine. 

The installation of this unit will allow the card feeding process to proceed uninterrupted.
