Recently,
Benjamin Noel followed a semi hauling a Kohler Power Systems generator. Warning
flags fluttered from its sides, yellow lights flashing caution. The generator
was one of the largest Kohler Power Systems builds, and Noel, a Kohler
associate with 37 years of employment under his belt, had built the housing for
the unit.
“Knowing
I was a part of building that?” he asked above the factory noise. “That’s
pretty neat.”
Noel
stood in the south end of the recently completed 105,000-square-foot addition
to the generator manufacturing plant in the Town of Mosel, north of Sheboygan.
Here, associates work three shifts, making everything from marine generators to
3.25-megawatt behemoths that power entire airports and military bases.
Although
many of the residential generators are built using mass production procedures,
larger units are often built to customer specifications. And while it’s
appropriate to stock inventory for mass-produced items, the nature of the
specialized units required an updated, responsive inventory system used
throughout the factory.
John
Brickner, director of manufacturing, said this system “is about having the
right part in the right place at the right time.”
Approximately
three days’ inventory is in the factory at any given time, with cutting and
bending of steel taking place the first day, painting on day two, and building
taking place the following day.
“We
turned this into a job shop,” Brickner said. “We focus on on-time delivery and
trying to get things out as quickly as possible.”
Helping
that along is one of the plant’s newest acquisitions, an Amada fiber laser,
which cuts some of the 25 to 30 million pounds of steel that passes through the
generator plant each year.
“The
precision on this is amazing,” Brickner said, watching the machine work. “It
can cut up to 140 inches per minute, and cuts up to five times faster than a
regular laser.”
Previously,
Brickner explained that when it came time in the manufacturing process to
enclose the generators, KPS sourced outside vendors. That step added time and
increased costs. The new addition provides space for the company to manufacture
its own enclosures, allowing KPS to offer “an entire solution to our
customers,” Brickner said.
The
philosophy of a “one-stop shop” means that KPS manufactures much of the
generators’ internal components – transfer switches, wiring harnesses, circuit
boards and switch gears – which provides competitive advantages like quality
control, decreased lead time, and cost savings.
“Our
controllers are designed specifically for power generation,” Brickner said.
“It’s a lot more interactive, with a focus on application.”
Brickner
said the longest build cycle, from planning to shipment, is 12 weeks; most
units are shipped in less time, and each unit stays on the shop floor being
built for four or fewer days. All generators are run through the testing bay
prior to shipment, an area that also allows customers to test generators and
request adjustments as necessary.
A
two-coat painting system, installed in 2010, creates what Brickner called “a
robust coating system” to protect generators from salty or harsh environments,
like those found in hurricane- and storm-ravaged sections of the country.
When
Hurricane Sandy struck in 2012, many East Coast businesses went long stretches
without electricity — KPS generators supplied power so grocery stores could
keep food properly preserved, and gasoline pumps could provide much-needed fuel
for customers.
Brickner said the demand for electrical power in the United States is growing “faster
than population growth, construction growth and GDP growth.”
That
situation, coupled with the country’s “antiquated and under-invested-in
electrical grids creates a need for quality power,” Brickner said. “If the grid
for the United States becomes overtaxed, we’ll have an increased need for reliable
power distribution at the customers’ point of use.”
Generators
certainly find their way around the world, but local companies also benefit.
Brickner tapped a smaller generator, its injection-molded enclosure made by
Bemis Manufacturing in Sheboygan Falls.
“We
source a lot of parts locally, whether it’s packaging or plastics,” he said.
“It supports the whole vitality of this area.”
