Ford Teases New Paint Tech

Time, money and pollution are top concerns for the auto industry today and Toyota’s latest invention—an airless paint atomizer—handles all three issues.
The claim by Toyota is that this is the first airless paint atomizer in the world to be used on car bodies. The technology supposedly provides coating efficiency over 95%. Meaning that over 95% of the paint actually sticks to the body. Typical paint atomizers only have 60-70% efficiency.

Toyota even thinks this new technique will lower their carbon dioxide emissions by around 7% due to the increased efficiency of the new atomizer.

One wold have to take a close look though to notice the difference between Toyota’s new atomizer and a traditional one. The most important difference is found in the tip where small parts distribute the paint. The airless atomizer has a spinning tip that make centrifugal force.

The tip includes six hundred some grooves that direct the paint. The spinning tip creates an electrostatic umbrella toward the car being painted. The grooves make the paint into tiny dots which are drawn toward the body of the car. With the air-based atomizers paint is essentially just being thrown at the car and what sticks is it.
The new tech from Toyota also creates a more even surface coverage.

Traditional paint atomizers are very sensitive to distance where was the new airless one monitors and adjusts the speed of its parts to compensate for changes in distance.

Right now the new airless atomizers are being used just in the Takaoka and Tsutsumi plants in Japan, but Toyota’s expectation is that the technology will eventually be used universally across its global manufacturing facilities.
