Feature | Investing in a down economy<br />

is a new venture, but would expand<br />

<strong>the</strong> company’s capabilities and allow<br />

it to do a wider variety <strong>of</strong> prototypes<br />

and short-run work. It’s something<br />

customers have been asking for.<br />

New technology has elevated<br />

Challenge Machine to a whole new<br />

level, Betland said. For that reason,<br />

<strong>the</strong> company makes a point to send<br />

representatives to IMTS and related<br />

shows each year.<br />

“There aren’t a lot <strong>of</strong> machines<br />

out <strong>the</strong>re for what we’re doing as far<br />

as micromachining,” he said. “We’re<br />

always looking for new ideas and new<br />

equipment in this area.”<br />

Proto Labs<br />

Proto Labs is a contract<br />

manufacturer that specializes in quick<br />

turnarounds <strong>of</strong> low-volume parts.<br />

“I think it’s safe to say we’re<br />

<strong>the</strong> fastest in <strong>the</strong> world at what we<br />

do,” said President and CEO Brad<br />

Cleveland. “And it’s because <strong>of</strong> <strong>the</strong><br />

technology we use.”<br />

Proto Labs has invested millions<br />

<strong>of</strong> dollars in s<strong>of</strong>tware and milling<br />

technology to automate all <strong>of</strong> <strong>the</strong><br />

manual processes that are necessary<br />

before a part can be milled, such<br />

as analyzing <strong>the</strong> geometry <strong>of</strong> its<br />

customers’ parts and programming<br />

<strong>the</strong> tool paths <strong>of</strong> its machines. As a<br />

result, <strong>the</strong> company can ship finished<br />

CNC machined parts or injection<br />

molded parts <strong>the</strong> next day.<br />

However, <strong>the</strong> company is more<br />

dependent on s<strong>of</strong>tware and computing<br />

technology than milling technology,<br />

Cleveland explained, because <strong>the</strong><br />

s<strong>of</strong>tware drives <strong>the</strong> automation.<br />

“We exist because <strong>of</strong> technology<br />

advancements that didn’t exist<br />

12 years ago,” he said. “We are<br />

completely dependent on proprietary<br />

s<strong>of</strong>tware that we’ve developed and <strong>the</strong><br />

Internet in general.”<br />

Indeed, technology has fostered<br />

rapid turnaround times as well as<br />

rapid growth. Since it was founded<br />

in 1998, Proto Labs has grown from<br />

zero employees to more than 300<br />

employees worldwide. Headquartered<br />

in Maple Grove, Minn. <strong>the</strong> company<br />

recently added full scale operations in<br />

Europe and Japan.<br />

<strong>Precision</strong> Tool<br />

Technologies<br />

<strong>Precision</strong> Tool Technologies,<br />

which makes prescription eyewear<br />

components, purchased over $2<br />

million in capital equipment over <strong>the</strong><br />

last year, including precision grinders,<br />

laser welders and a laser engraver.<br />

It also opened a second facility in<br />

Brainerd, Minn.<br />

“Five years from now, 80 percent<br />

<strong>of</strong> what we’ll be doing we’re not<br />

doing today,” said Jim Goerges,<br />

president. “What that expansion<br />

equipment allows us to do is work<br />

around <strong>the</strong> clock. It is automatable<br />

and can run unattended.”<br />

Despite a steep drop in sales<br />

and budget cuts, <strong>Precision</strong> Tool<br />

Technologies purchased <strong>the</strong> equipment<br />

anyway, having learned a few lessons<br />

from <strong>the</strong> downturn in 2001.<br />

“When we were doing equipment<br />

expansion in 2001, we sped right<br />

through that deal,” Goerges said. “This<br />

downturn is a little deeper and steeper.<br />

But we’re still long-term focused.<br />

We’re not going to jump <strong>of</strong>f <strong>the</strong> track<br />

because <strong>of</strong> a short-term blip.”<br />

Haberman<br />

Machine<br />

Prior to August <strong>of</strong> 2009,<br />

Haberman Machine had been<br />

running 24 hours a day, 7 days a<br />

week. Maxed out in capacity, <strong>the</strong><br />

company decided to purchase<br />

additional equipment and open a<br />

second facility in Stillwater, just<br />

5 miles away from its Oakdale,<br />

Minn., facility.<br />

Then <strong>the</strong> company began to<br />

experience a ripple effect from <strong>the</strong><br />

recession.<br />

“We had a tough fourth quarter<br />

last year and first quarter this year,”<br />

said Kimberly Arrigoni, Haberman’s<br />

controller. “The slowdown was<br />

painful on top <strong>of</strong> our expansion. Our<br />

second quarter has been much better<br />

and signs are <strong>the</strong>re that we are getting<br />

through it.”<br />

In November, Haberman Machine<br />

opened a 10,000-square-foot facility<br />

and is running currently both<br />

facilities 6 days a week, 24 hours<br />

a day. Its goal is to produce parts<br />

“better, faster and cheaper” in order<br />

to compete in today’s marketplace.<br />

“We were fortunate to be able<br />

to take advantage <strong>of</strong> <strong>the</strong> sales<br />

opportunity on our building<br />

and equipment,” said Scott Ness,<br />

Haberman’s sales engineer. “For once,<br />

we were at <strong>the</strong> right place and time<br />

to be able to capitalize on what <strong>the</strong><br />

market was <strong>of</strong>fering.”<br />

The equipment Haberman<br />

Machine purchased was a Zeiss<br />

coordinate measuring machine,<br />

two Fanuc RoboDrills, and eight<br />

Kitamura horizontals, two <strong>of</strong><br />

which are 5-axis. The company also<br />

purchased a central mix and makeup<br />

system to continuously recycle<br />

its coolant, just one <strong>of</strong> <strong>the</strong> many<br />

elements that makes its building a<br />

green manufacturing facility. In fact,<br />

Haberman is <strong>the</strong> only manufacturer<br />

in <strong>Minnesota</strong> with this type <strong>of</strong> a fully<br />

automated system.<br />

“Everything is set up to run<br />

24 hours a day for lights out<br />

manufacturing,” Ness said. “We<br />

positioned our organization to be<br />

able to support our current customer<br />

base and be ready to expand with<br />

new customers once <strong>the</strong> economy<br />

recovers fully.” PM<br />
