In the Works Toyota's Georgetown, Kentucky, assembly plant is its largest outside of Japan. It makes a half-million cars a year--one every 27 seconds.
Finish Line: A worker does final inspection. Toyota's assembly lines make thousands of changes a year to how the work is done.
Deep inside
Georgetown's paint shop is vast and crowded, but in two places there are wide areas of open concrete floor, each the size of a basketball court. The story of how that floor space came to be cleared--tons of equipment dismantled and removed--is really the story of how Toyota has reshaped the U.S. car market.
It's the story of Toyota's genius: an insatiable competitiveness that would seem un-American were it not for all the Americans making it happen. Toyota's competitiveness is quiet, internal, self-critical. It is rooted in an institutional obsession with improvement that Toyota manages to instill in each one of its workers, a pervasive lack of complacency with whatever was accomplished yesterday.
The result is a startling contrast to the car business. At a time when the traditional Big Three are struggling, Toyota is thriving. Just this year,
Toyota doesn't have corporate convulsions, and it never has. It restructures a little bit every work shift. That's what the open space in the Georgetown paint shop is all about.
Chad Buckner helped clear the space. Buckner, 35, has a soft Southern accent and an air of helpfulness. He is an engineering manager in the painting department, where he arrived straight out of the University of Kentucky 13 years ago. His whole career has been spent at Toyota.
As recently as 2004, a car body spent 10 hours in painting. Robots did much of the work, then as now, but they were supplied with paint through long hoses from storage tanks. "If we were painting a car red, before we could paint the next car white, we had to stop, flush the red paint out of the lines and the applicator tip, and reload the next color," Buckner says. Georgetown literally threw away 30% of the pricey car paint it bought, cleaning it out of equipment and supply hoses when switching colors.
Now, each painting robot, eight per car, selects a paint cylinder the size of a large water bottle. A whirling disk at the end of the robot arm flings out a mist of top-coat paint. When a car is painted--it takes just seconds--the paint cartridge is set back down, and a freshly filled cartridge is selected by each robot.
No hoses need to be flushed. There is no cleaning between cars. All the paint is in the cartridges, which are refilled automatically from reservoirs. Cars don't need to be batched by color--a system that saved paint but caused constant delays. Cars now spend 8 hours in paint, instead of 10. The paint shop at any moment holds 25% fewer cars than it used to. Wasted paint? Practically zero. What used to require 100 gallons now takes 70.
The benefits ripple out. Not only does Georgetown use less paint, it also buys less cleaning solvent and has dramatically reduced disposal costs for both. Together with new programming to make the robots paint more quickly, Buckner's group has increased the efficiency of its car-wash-sized paint booths from 33 cars an hour to 50.
"We're getting the same volume with two booths that we used to get with three," Buckner says. "So we shut down one of the booths." If you want to trim your energy bill, try unplugging an oven big enough to bake 25 cars. Workers dismantled Top Coat Booth C, leaving the open floor space available for some future task.
So what do Buckner and his crew do with a triumphant operational improvement like that? By way of an answer, he walks to the second area of open space, where the sealer-application robots used to sit. They've been consolidated, too. Buckner points to another undercoating booth that the engineering staff is now working to eliminate.
