allows us to serve a wide range of industries," Rittmeyer says. "Having this
diversity allows us to maintain our business even as one market is down, as we
hope the others will help carry us."
The company prides itself on its
technical knowledge and customer service, and does not rest on its
laurels when it comes to customer
retention. "Even if we already have
a company as a customer, we're always acting as though we don't,"
Rittmeyer says. "We're always trying to earn our customers' work and
don't expect them to just give it to
us, even if we've been working with
them for decades."
Hoosier Pattern considers itself
a solutions provider to its customers' casting needs, even if that occasionally means recommending that
a customer use another company's
services. "If we can't offer a solution, we will tell people what that
solution is and where they can find
it," he adds. "Even if it's another
company providing that solution,
our customers will still come back
to us in the future."
The company often goes out of its
way when it comes to serving customers. Last fall, a customer called Rittmeyer on a Saturday morning while

he was on a hunting excursion. The
customer needed a printed core for a
42-inch open-faced impeller as soon
as possible because it had a facility
shut down.
"We started printing on Saturday
afternoon, and by Sunday morning we
cleaned the core, packaged it and sent
it to the customer, who received it
early Monday morning. The end customer took receipt of their casting on
Wednesday," Rittmeyer says. "When
you get a call to come off a deer [hunting] stand on a Saturday and work all
Saturday and Sunday, that's going
above and beyond."

Finding Better Ways
Hoosier Pattern's 50,000-square-foot
facility includes 3-D printers as well
as 25 machining centers. It regularly updates equipment and processes
to make them more efficient. "We're
constantly evaluating if there's a better way to do things, and examine different machines, software and technologies," Rittmeyer says. "We're not
opposed to trying a new method to
make ourselves more efficient."
The company in June enhanced its
additive manufacturing capabilities
when it installed a Voxeljet VX1000
printer that prints consumable pat-

terns composed of polymethyl methacrylate (PMMA). These patterns
are utilized in investment casting
- a technique that involves forming
a mold around a pattern of material
that is then removed.
"The ways to benefit customers with
this printer are endless. It will speed up
processes and products to our customers for quicker turnaround times," the
company says, noting the printer has a
one-week lead time. "This is just one
more tool in our toolbox to offer solutions to our customers." mt
