Stories From The Field: Automotive Plant Tour

Throughout my years I have been in many manufacturing facilities. Oddly enough, I have seen nearly every part of a passenger car manufactured and then fully assembled. The amount of compressed air applications in automotive supplier and manufacturing facilities are tremendous. Here are some stories from just a few we have encountered over the years, and all of them can be found in our Application Database.

Air Wipe – How it works
  1. A component manufacturer, specifically a steering and transmission component manufacturer was having issues with machined parts coming out of a CNC machine with too much oil based cutting fluid on them and not passing inspection process because the oil would throw off the automated measuring system. The part was a splined shaft that the high surface tension oil stayed in the splines. The part was removed from the machine via robotic loader and set onto a fixture. The path to the fixture was outfitted with a Super Air Wipe so the robotic loader could move the part into and out of the air wipes’s airflow and remove the oil. The converging airflow of the Super Air Wipe was ideal to keep the peaks and valleys of the shaft clean of oil and they were able to direct oil back into the cutting machine so no separate collection system was needed.

2. A seat bracket manufacturer had issues protecting the lenses on their vision systems from welding spatter. They were again able to reduce the replacement / repair downtime by installing a 9″ Super Air Wipe in front of the robotic mounted lens and keep the spatter / fumes from ever making it to the lens, resulting in expanded run times between repair / downtime.

Cooling with Air Amplifiers

3. A forging company manufacturing the pistons was having issues reducing the temperature of the pistons as they were assembled to the connecting rods. The solution for them was to install a series of Super Air Amplifiers over the fixtured, indexing line and at each dwell station a Super Air Amplifier would activate and cool down the assembly by moving large volumes of ambient air mixed with small amounts of compressed air onto the surfaces.

4. An automotive manufacturer had issues with stamping shavings and welding debris staying on the surface of parts and fixtures resulting in rework and defective parts. Implementing a series of Super Air Nozzles, and Super Air Knives resulted in debris removal that saved tooling rework as well as production reject parts.

5. Another automotive / recreational vehicle manufacturer needed help with their torture test machine for suspension components. They were utilizing fans to try and keep shock sensors cool and replicate air movement. electric fans were not able to provide a focused airflow and so enter the Super Air Amplifiers. These have also been utilized on engine torture test machines.

EXAIR Nano Super Air Nozzles for Science and Industry!

A few weeks ago I was on vacation with my family. My wife and I had taken our three daughters to Columbus, OH for three days after camping in a tent for a few days. One of the focal points to the trip was COSI, the Center of Science and Industry. In case you live anywhere near Columbus, OH and have not heard of how amazing this interactive museum is, you should definitely check it out. This isn’t your normal museum.

While the Mythic Creatures exhibit and the Jim Henson exhibit were both absolutely amazing for my 9, 6 and 4 year old daughters, it was also entertaining for my wife and myself. Now you may be asking what does this interactive science place and trip with kids have to do with EXAIR.

Well, while my daughters and I were watching this enormous pendulum that knocks ball bearings off boxes every few minutes I could hear that all too familiar, gentle sound of compressed air blowing every now and then. I couldn’t however see where the noise was coming from.

COSI Pendulum

As we wandered through the different sections I saw several examples of compressed air use but none were the exact sound or display I had heard. When we were walking through the Space exhibit just above where the pendulum was located and that gentle sound was getting closer. All of a sudden I saw it. Next thing I know I look up and my 6 year old was using a joystick to control a scaled down Lunar Lander propelling it in circles. This was where the sound was coming from.

While I was amazed by this interactive piece I could tell they were using compressed air and I was curious as to how it was working. That’s when I noticed the distinct design of our Nano Super Air Nozzle on the bottom of the Lander. Here’s a close up picture, well as close as the handrail would allow me to get without over reaching.

The interesting part to this is how this setup gives an idea of the amount of thrust given off by a nozzle that only consumes 8.3 SCFM of compressed air when powered at 80 psig inlet pressure. These nozzles can easily be fitted to blast debris or moisture out of small pockets or hard to reach areas. They also can be used to help direct product that may be getting diverted to a new conveyor. And, obviously, they can be used to propel scale models of lunar landers. 

If you would like to discuss any application for point of use compressed air, and I do mean ANY, give us a call. If I can’t help with the application we will at the very least do our best to send you in the right direction.

Compressed Air Uses In Industry

From pneumatic hand tools like impact wrenches or nail guns to larger scale industrial applications like stamping presses, the use of compressed air can be found in almost any industry. In fact, it is often referred to as a “fourth utility” next to water, gas and electric.

Compressed air is used in virtually every industry!

 

Take for example in construction, workers will use a pneumatic riveter to join steel framing because of the power generated by the tool over an electrically powered device, not to mention it provides for a safer operation by removing an electrical hazard. Many companies use compressed air operated diaphragm pumps or air motor driven pumps to move expensive or viscous liquid from one location to another. These types of pumps are self priming drawing the liquid in and provide positive displacement meaning they fill and empty the liquid chamber with the same amount of liquid through a common inlet and outlet.

Amusement parks have used compressed air in some capacity in the operation of thrill rides like roller coasters or to enhance the effect of certain attractions. Compressed air can be found in hospitals where it is used for specialized breathing treatments or to power surgical instruments in an operating room. Educational facilities use compressed air for laboratory testing. You can even find compressed air in the tires on your car. Basically, when you think about it, compressed air is being used just about anywhere.

Here at EXAIR, we manufacture Intelligent Compressed Air Products to help improve the efficiency in a wide variety of industrial operations. Whether you are looking to coat a surface with an atomized mist of liquid, conserve compressed air use and energy, cool an electrical enclosure, convey parts or dry material from one location to another or clean a conveyor belt or web, chances are we have a product that will fit your specific need.

EXAIR has been providing engineered solutions since 1983.

Stretch Wrap Static Solution

Recently a customer called in to EXAIR to discuss a static issue in a stretch wrap process in the plant. Stretch wrap is a highly stretchable plastic film.  The elastic recovery keeps the wrapped load tightly bound. The most common stretch wrap material is a linear low-density polyethylene or LLDPE.  The combination of the stretching of the plastic film and the sliding of the film on the cardboard boxes as it is being wrapped causes a build up of static. This static can cause serious havoc and issues in the process including personnel shocks, zapping counters and other sensors causing failures, and preventing marking systems from delivering good information on to the stratch wrap.

Stretch Wrap Operation

The discussion started with minimum and maximum load sizes and how to design a system that would work with all configurations and be as flexible as possible.  We spoke of dimensions and where we could we could mount on 3 sides, and so forth.

Then came the question that we invariably get to and that is ‘what issue does the static cause and how does it affect the rest of the process?’  The answer here simple, ‘an operator has to write a code number on the side and affix a label, and in doing so, receives a shock.’ When it was determined that only a small section of one side of the load needed to be treated, the solution was simple.  We proposed an 18″ Ionizing Bar and Power Supply. Because the machine had a fixed datum, all loads would pass within 1-2″ of a vertically installed Ionizing Bar, so no adjustment is needed for different load sizes.

The Ionizing Bar quickly dissipates a strong static charge as shown in the chart below.
