Cooling a Laminating Process

We have a customer who uses a large laminating machine to place a protective plastic coating on their product. These large panels are laminated two at a time and are manually removed from the process. As you will see int this video, they currently use two Soft Grip Safety Air Guns to manually cool the silicone blanket covering the product before they can remove it and get to the product.

I have found that with the video inserted into the blog, there is not a great deal to explain about the application. However it does show the effectiveness of removing heat from a material by just using ambient temperature compressed air. The temperature differential between the silicone pad and the compressed air temperature is great enough that even 80F compressed air is removing the heat.

Many times we use the analogy of using your breath to cool your coffee. Your breath is about 85-90F but still has the capacity to remove heat from your hot coffee because the coffee is significantly hotter at 170-180F. Many times customers think they must have a cold air source to cool, but it simply depends on the temperature of the surface you are trying to cool.

The same is true for this application, the silicone blanket is very hot and needs to be brought down to a temperature where they can touch it with the gloves they are wearing. Without the cooling from the Soft GRip Safety Air Gun the heat from the silicone blanket penetrates through the gloves and makes it difficult to properly remove the blanket. Fumbling with the hot blanket increased cycle times and created an unpleasant working environment.

Problem Solvers

 I received an overwhelming surprise this morning.  In my past blogs, I talked about recycling and my harrowing experience at the grocery trying to find chipotle mustard. The president of the company came to my cubicle and handed me his old I-Phone. He had upgraded to the new 3G and was going to trash the old one. After reading my blogs, he  was inspired to recycle the phone and help me with my grocery store problem. Wow! The president reads my blogs…awesome.

On the phone there is a shopping list application. This is way too cool. You type in the item, it adds it to your list and tells you where in the store it can be found. Guess what? Chipotle mustard is listed in ethnic foods! The downside to this  app is that it is associated with a website. So while I am busy at work earning the bacon, my wife via the internet can be adding bacon to my shopping list along with anything else that she wants me to pick up on the way home. Technology, is it great or what?

EXAIR is always on the leading edge of technology; in the way we communicate with our customers and with the air saving designs of our products. The digital age has transformed the way we all do business and EXAIR embraces that. We have made technical information more available through our extensive website. In the past, process engineers were dependant on the knowledge of their local distributor which understandably, may not have been all that extensive. We welcome customers to contact our engineers here at the factory either by an online chat, email, fax or phone.

A recent example is  our customer that reclaims old plastic bottles. He grinds them up, mixes pigments and oils, extrudes them into a flat sheet and  then dices them up into 1/4″ cubes. These are then bagged and sent to injection molders. The problem that he was having is separating out the bottle labels from the re-grind. Some are paper and others are highly pigmented plastic, both are unsuitable for reprocessing.

He contacted some distributors only to have to wait a week or so until their outside sales guy could make it in to see him. Then all they suggested was a blower which he tried before and it did not work. Taking matters into his own hands he started searching the internet and came across our website. He requested an online chat and that is how he and I hooked up. Within minutes he had his answer.

I suggested that he install an EXAIR air knife to blow the lighter stuff away.  I gave him pricing and delivery and the confidence of EXAIR’s 30 day unconditional guarantee. He placed the order and later told me that it worked perfect out of the box. He said that he should have gone to the internet first and saved himself time and grief. Is technology great or what!?

I enjoy sharing my experiences and would like to hear some of yours.

Super Ion Air Knife Used in Making Golf Balls

Golf balls, in their simplest form are a hard, thermoformed plastic molded over a rubber core. Once the ball is formed, many subsequent steps to polish off parting lines from the mold and refine the overall finish of the dimpled exterior leave a layer of dust behind which can be attracted back to the ball surface by way of static electricity generated during these processes.

The customer, a well-known sports equipment manufacturer, contacted EXAIR to determine the best way to go about setting up an automatic blow off station using ionized airflow. After going over the details to determine if there were any limiting factors that might keep us from setting things up exactly how we wanted, we found that a combination of Super Ion Air Knives were the best way to go. One Super Ion Air Knife kit and one additional Super Ion Air Knife were set up to blow in at the ball which can spin on an axis in a fixture to allow for complete exposure to the ionized airflow.

A quick blowing with the Super Ion Air Knives was all it took to remove the debris and allow the customer to move on to printing and clear coating the balls.

If you have any sort of automated manufacturing process that involves generation of dust and debris similar to this, give some serious thought to use of the Super Ion Air Knife for blowing off of your product.

Put Up or Shut Up

The world has changed.  Business has changed.  Websites, Facebook, YouTube, Twitter, blogs and the like have enabled communications in ways not envisioned even a few years ago. 

As a businessperson, that is both good and bad for you.

On the “good” side of the ledger, information is more readily available than at any time in human history.  A few keystrokes typed into Google will yield a world of results for your perusal.

On the “bad” side, how can you judge these sources of information?

In an hour’s time, anyone can build a basic website, blog or Facebook page and proclaim that they are the “intergalactic leader” for any sort of product, service or technology.  High school book reports are generally required to contain more objective evidence than is found to support the claims of some companies on the “interweb”.

How will you judge the legitimacy of the source?

Here are the questions that I ask:

1. What is the most trusted brand in this particular category?

Generally one brand rises above all others because of a history of performance, innovation and reliability.

2. Who is the market leader in this particular area? 

Leaders are “first”, “largest”, “best” or “only”.  Followers imitate leaders, most often poorly.

3. How experienced is this company in their chosen field?  How does that level compare to the leader? 

Past performance is the best predictor of future performance.

 4. Is there more to this company than a virtual storefront?  Do they have an office?  A factory of their own? 

Virtual offices and contract warehouses raise serious credibility issues.

 5. Is this company innovative?  Are there any third parties or objective evidence to prove it? 

If the company truly ever did anything unique or noteworthy, proof would exist.

Claims are easy.  Proof is hard.

It’s time to put up or shut up.
