Magic Forcefields and Practical Applications

It is clear from watching my sons that having super hero qualities and powers is something they think of often. My youngest desires to be like the Human Torch from The Fantastic Four, so he has given himself a proper name – The Match.

His brother tends to desire all of the coolest qualities from a variety of different super heroes, he prefers the power of sonar, unlimited strength, X-ray vision and the power of producing force fields. He has let me know that any super hero with these kinds of power would be so well-known that a cool name would not be necessary.

So as I make my way through the house and our typical town environment it is not unusual for me to be set ablaze or saved from falling leaves or even bird poo by a force field. I know, I know…yes my life is full of danger, exciting and enviable.

It does, however, bring to light a quality of our Super Air Knives; the laminar air flow which is often used to create a barrier like a force field. I recently spoke with a customer who machines wood with a CNC router. The router is shrouded on three sides by brushes to help contain the wood dust for the vacuum system to remove. The fourth side is open so the tool changer can switch bits. They outfitted this open side with a Super Air Knife to assist keeping more dust contained and removed.

It is also common to keep heat inside of an oven by mounting a Super Air Knife at the opening and blowing air a t a very slight angle into the oven. This has helped many customers from losing additional heat out of the ovens.

And barriers to contain coolant mist inside of a machine or to keep spatter from falling on lenses of laser cutting machines are also tried and true solutions.  It stands to reason that if we can help with weld spatter and mist, we can also contain fumes and smoke for many applications.

So the next time you would like to implement a “force field” at work let us know, you too can be a super hero.

Making Dog Biscuits

Customer forms dog biscuits from a dough using a roll press. The problem they were having is that as the day wore on, the roll gained heat and caused the dough to stick to the roll. This caused defects in subsequent formings. They were experiencing 25% reject rate.

The operators discovered that by blowing compressed air onto the cavities, they were able to  keep the heat build up in check. The problem with that set up was that it used too much compressed air. Their chief engineer had a blower installed as a substitute for the compressed air but it did not work and the operators went back to using compressed air.

Looking for a solution to excessive compressed air consumption, their chief engineer turned to EXAIR for assistance. We recommended installing a 36″ air knife model # 110036 . As its design is to entrain surrounding air, only a nominal amount of compressed air was required to deliver the volume of air needed to provide adequate cooling. Both problems solved- die cooling and compressed air consumption.

Super Air Knife Best Thing Since Sliced Bread in Bakery Application

You have heard the expression before.  Now we get to actually get to apply a Super Air Knife into a bread slicing machine! The customer is a bakery that produces various types of bread on a large scale production basis. The  action of slicing bread produces quite a mess with bread crumbs flying all over the machine and the immediate area around the machine. Turns out bread crumbs are like little ball bearings when you walk on them which makes walking around the machine area quite dangerous. The crumbs also tend to fly up into the machine operator’s face as well which is not a desirable condition to have from a worker safety standpoint.

The customer was looking for a way to contain the bread crumbs during the cutting process and so decided to use our Model 110024SS 24″ Stainless Steel Super Air Knife to deflect and blow the crumbs down into the machine where they can be contained by the sheet metal protection within and then cleaned up later at the end of a shift or when time permits.

It is a simple application but one that makes all the difference in the world to the operators working around the bread slicer.

Cold Gun Performs Double Duty

I got a call from an industrial supply company last week who had a customer looking for two solutions for one application.  They machine parts out of PEEK plastic.  The bit was getting too hot, creating warping and other heat-related damage.  And, not all the machining shavings were being fully removed from the parts.  Both of these problems were leading to an excess amount of rejected material.

I was able to recommend one product from our Spot Cooling line that would solve both problems.  I suggested they offer a Model 5315 Cold Gun with Dual Point Hose Kit.  One of the arms can be directed right at the bit to provide cooling.  The other can be directed at the point of cut, to ensure proper removal of the chips and shavings created. 

A quick, easy solution to handle two problems at one time and eliminate the rejected material issues.
