E-Vac For Lubricant Recovery

Over the last 3 months, I have been in contact with a customer, keeping track of an application that involved the EXAIR E-Vac.  The customer had reached out to us looking for some advice on how to solve a process problem. The operation is a drawing/stamping process, and the when the part exits the machine there is coolant that resides in a deep draw section, approx 0.4″ in diameter by 3.5″deep.  About 1 oz of coolant per part is retained, and over many 1000’s of parts, would add up to lost dollars and messy clean up.

The customer was looking for an automated process that would be able to draw out the coolant and direct the liquid back to the coolant reservoir, all while maintaining the current machine run rate. We settled in on the model 840015 Adjustable E-Vac Generator. The Adjustable E-Vac has a straight through pathway from suction through to discharge, allowing for fast evacuation times.  A simple turn of the unit changes the vacuum and flow levels to best match the needs of the application.  The Adjustable E-Vac coupled to a solenoid valve controlled by the stamping machine resulted in the automatic system the customer was looking for.

The customer ordered a unit, and based on the preliminary bench testing, it was approved for a production run trial. After some tweaking in the production environment, the unit was performing to spec, and was then subjected to a 100,000+ part run.  The results were a success!  Instead of the parts exiting onto an inclined conveyor, relying on gravity to drain and causing coolant to collect under the conveyor, the coolant could be removed in a controlled manner and sent back to the reservoir.  Less mess and no coolant loss.

EXAIR manufactures (3) types of E-Vacs – Low vacuum generators for porous materials, high vacuum generators for non-porous materials, and the adjustable type for flexible vacuum performance.  They are available in multiple sizes, to best match the vacuum requirements, while using the least amount of compressed air.

To discuss your application and how the EXAIR E-VAC can benefit your process, feel free to contact EXAIR and myself or one of our other Application Engineers can help you determine the best solution.

Excellence Is Not An Act, But A Habit

“We Are What We Repeatedly Do. Excellence, then, is not an Act, But a Habit”

In my twitter feed I often see the aforementioned quote that is attributed to Aristotle. As this blog points out, the quote should really be attributed to Will Durant author of The Story of Philosophy, because it is his interpretation of what Aristotle would have said if he spoke English. While writing this blog I found out Aristotle didn’t really write the quote. In retrospect, clearly he didn’t write, if he did it might look something like this “Είμαστε Τι επανειλημμένα Do. Αριστείας, τότε, δεν είναι μια πράξη, αλλά μια συνήθεια”, but I digress.

Working with customers, resellers and catalog houses, I’m amazed at the different company cultures. Some customers will come to me six months before a project comes up to talk about the applications. They ask us for drawings, specifications, and certifications for the products that we recommend for their applications. They want to analyze all possible scenarios and plan for every eventuality.  These customers greatly appreciate our fully loaded knowledge base and availability of technical information.

Other customers call me for a quote and confirmation. They spent some time online, downloaded a CAD model and created a working plan, but before they pull the trigger, they want to run it by someone else. These customer greatly appreciate the fact that the phones are answered by human beings and we have a fully staffed Application Engineering department with engineers who are always eager to discuss applications and possibilities.

Finally, we have the customers, who I never spoke to before that need a product NOW and are willing to do anything to get. Shipping companies love these customers, because we have our products on the shelves ready to ship, but it will cost you air freight and a flux capacitor to get it there yesterday.

 

At EXAIR, our culture expects excellence. And no matter the kind of customer who contacts us, we know you are all trying to achieve it too – we are just trying to help. When our customer calls in to ask for something yesterday, we will already have it on the shelf ready to go. Unless it is a custom product, our production staff has already machined, built, and tested our product to our excellent standard.  I’m constantly amazed at the effort and continued excellence put out by customer service, engineering, marketing, and production. When the customer calls in to ask for product yesterday, 99.98% of the time I’m able to say that the shipment will be at the dock waiting for the shipping truck by 3:00 PM EST. We can typically do that without an extraordinary effort, because we practice excellent customer service everyday. It’s a habit we are not trying to quit.
