Prent: A 'Pace Maker' in the
Medical
Thermoforming Industry
Recently named
Wisconsin's thermoformer of the year, Prent Corp.'s custom
thermoforming business offers quality packaging and product
development.
By Chad
Sypkens
Prent Corp., a manufacturer of custom thin wall
thermoformed packages for the medical, electronic and
consumer industries, is an ISO 9001 certified custom
thermoformer specializing in medium run, deep draw,
nestable, high-quality precision parts.
Prent's core business is custom thermoforming. The
company's primary markets include the medical and
electronics markets.

the 24 thermoformers designed and built in-house.
Each of the three clean rooms has eight machines
capable of forming and trimming medical packages
in-line.

Prent averages 250 setups each month, half of those being
custom business. Custom can be defined as setups running an
average of 2 to 4 hours and producing 10,000 to 15,000
parts, with the other half of the business typically
performing 16 to 32 hour runs. Very few of these production
runs will go five to six days before setting something else
up.

Prent
History
Prent was founded by Jack Pregont Feb. 13, 1967,
with production beginning in a 10,000-square-foot
former silo manufacturing building in Janesville,
WI. With an initial employment of 15 people, the
company specialized in thermoformed packaging,
injection molding and decorating. By remodeling the
facility in 1970 and adding an additional
16,000-square-feet, Prent established its model and
tool department with employment now up to 35
people.
By 1973, Prent's sales had doubled for the sixth
consecutive year and the work force eclipsed 100.
The company broke ground for a 50,000-square-foot
facility and began production of Glade Solid Air
Freshener packaging for S.C. Johnson Wax. In the
following 15 years, Prent received a patent for the
3 panel fold-up (Rack' n Stand) which became an
industry standard, thermoformed the first RF-welded
"twinwall" package, invented the "fade away" hinge,
utilized computerized drafting and design
technology for new package development and became
the first climate-controlled thermoformer in North
America to have its entire facility air
conditioned.
Now employing close to 500 people, Prent was
also the first custom thermoformer to gain ISO
9001status. Prent operates domestic plants in
Janesville, WI (corporate headquarters), and
Flagstaff, AZ, and new global manufacturing
facilities in Johor Bahru, Malaysia and Costa
Rica.

Thermoforming
Flexibility And Continuity
From Start to Finish
A family-owned, privately held company, Prent handles
jobs from start to finish. Coming up with initial concepts,
creating the models, constructing the tools needed to form
the package, Prent brings the project to the point where it
needs hard tooling to put on production thermoformers, then
makes the tooling. All this, at no extra cost to the
customer.
"If we can handle a project from beginning to the end,
involving no one else for the most part, we will. Our
obligation to our customer typically is the package, but we
want to meet and exceed the customer's service requirements
as well," says Walt Walker, executive vice president of
operations at Prent Corp., which has operations in
Janesville, WI, Flagstaff, AZ, Johor Bahru, Malaysia and San
Jose, Costa Rica.
Vertical integration is evident at each of Prent's
locations. "If you took a tour of all of our facilities, you
would see a lot of similarities and a lot of continuity for
all the right reasons. This is a proven text-book way to run
a business. When you see a row of thermoforming machines
here or at our Flagstaff location, they are all mirror
images of each other," says Walker. "We have the flexibility
in that we aren't held to run a certain job on a certain
line. It also allows us the luxury to not have to depend on
anyone else. Jobs can be run on any of our lines. It is
fantastic for training and maintenance &emdash; line 8
today, line 15 tomorrow, whatever."
Walker explains it as the same philosophy that McDonald's
used when it decided to expand its franchise around the
world. "They wanted to make sure that when people ordered a
Big Mac in Chicago and a Big Mac in Taiwan, they tasted the
same. That is the same philosophy that we have with regards
to our packages," says Walker. "We have to produce packages
for our customers who have locations in different parts of
the world. They want to know that when the package is
developed, designed and proved out at corporate here in
Janesville, that when we produce that package at one of our
other sites around the world that package will function
exactly the same way.
"It has to be that way and we have to maintain control in
order to do that &emdash; designing, developing and proving
out," explains Walker. "Once that first production run is
done and we have successfully met the expectations of the
customer, we can package up the information that we
generated here and send it to any of our other plants which
have the same identical equipment and same operating
procedures. All they have to do is install it the same way
and they will be able to produce the same quality product
that we started here."
According to Walker, in the thermoforming industry the
clean room is the jewel; Prent is utilizing this jewel to
the best of its ability. Prent has three clean rooms at its
Janesville location and one in Arizona.
"We have found that eight of our thermoformers in one
clean room is the way to go and that is what we have done
here and in Flagstaff," says Walker. "That allows one
individual to manage that room by himself &emdash; including
order entry, ordering materials, scheduling and hiring
personnel. He is essentially managing a company within a
company."
Prent's Thermoforming
Process
A thermoformed part starts with design, and Prent's
award-winning development group combines experience with
computer technology and innovation to achieve the best
solution to each project, according to Walker. Customers
choose designs from numerous concept drawings and solutions
are then detailed using CAD technology, allowing accurate
modeling and sampling to prove out the package function.
Prent makes hand samples from its models to show size,
basic function, product layout and color. A large variety of
thermoplastic material is stocked to meet those needs.
Prent also has the luxury of having one of its suppliers
of plastic material within shouting distance. The proximity
of the two businesses has been a unique relationship and has
proven to be a successful one for both.
"We were stumbling at a period of time where our customer
demands 15 years ago were greater than the materials we
could purchase to meet those demands," says Walker. "We took
control of the raw materials that we needed to satisfy our
customers."
"If it is out there and it is being extruded to be
thermoformed, we are using it," says Walker. "If it's
marketed for thermoforming and if our customers have a need,
we will work with them. If a customer has a choice and they
aren't sure if they want it in styrene or PETG, by the time
we go to cut the aluminum for the tool, we have to know
because how you space the cavities and design the tools is
completely different from one plastic to another."
"What the package is going to be exposed to will
sometimes answer the question (of what material to use) for
you," says James O'Dierno, senior vice president of sales.
"Is it clear? Is it for the medical business? Does it have
to be sterilized? How do you want it sterilized? Answer
those questions and that pretty much starts to dictate where
you're going to go. There are times where that same part can
be made out of two different materials but the tooling is
developed for a particular plastic."
Prent supports a complete in-house tooling facility,
utilizing computer, digital and other state-of-the-art
technology to produce quality form tools at minimum cost. As
the business moves around the world, the same tools, same
equipment, same operation and the same process is utilized.
Prent has 24 identical thermoformers with inline trimmers in
Janesville, WI, eight in Flagstaff, AZ, five in Johor Bahru,
Malaysia, and three in Costa Rica.
"We have around 300 customers and a tool base to satisfy
those customers in excess of 1,000 active tools. It is quite
an extensive operation," says Walker, "to design the
packaging, satisfy the customer's needs, come up with
concepts, do the modeling, make the tools, bring the package
to the point where they need hard tooling to put on the
production formers to produce the packages. To bring it to
that point at no charge to the customer is unique."
Once Prent's design team starts working on a product,
Walker says they must have a pretty good idea that it will
have a great chance for business and the investment
(tooling, design and time) will be worth it.
"We can't afford to spin our wheels," says Walker. "It
becomes so important to meet today's needs and expectations
of the customers because many companies are doing concurrent
manufacturing or concurrent engineering. We are actually
designing virtual packages for products that don't even
exist yet. In order to do those kinds of things right and
meet time lines, there has to be a pretty successful
qualification rate."
Once thermoforming is completed secondary operations may
have to be performed. Roughly 10 percent of what Prent
thermoforms will need some type of secondary operation.
"Whether it be decorating, sealing, RF sealing, sonic
sealing or solvent sealing." says Walker. "We may punch
additional holes into a part or package, decorate it with a
label or use hot stamping or pad printing procedures. Once
again, doing what needs to be done to satisfy the
customer."
Award-Winning
Corporation
Prent has earned state and national recognition for its
thermoformed products.
"A big recognition we were given last year was when
Wisconsin Governor Tommy Thompson awarded us the
Manufacturer of the Year award for the state of Wisconsin
for all large companies," says O'Dierno. "That in itself
made quite a statement about who we are, our attitude and
where we are going."
The Manufacturer of the Year awards program is
co-sponsored by the state's largest business association,
Wisconsin Manufacturers & Commerce (WMC) and the
nation's thirteenth largest CPA firm, Virchow, Krause &
Co.
On the national level, Prent received awards from the
Society of the Plastics Industry (SPI) this year including:
Thermoforming Package of the Year, Medical Package of the
Year and Consumer Package of the Year.
Prent's design of a coronary imaging catheter package
received first place in the "Light Gauge Medical Packaging"
category and was also honored as the "Thermoformed Package
of the Year" at the SPI Thermoforming Institute National
Awards (TINA) ceremony held in March. This sterile barrier
package suspends and immobilizes a fragile and expensive
fiber-optics catheter coil and accessories. It additionally
serves as a protective shipper, a prep station and a
catheter channel for the product. The package is nestable,
even with an RF sealed channel. It captures the accessories
in the unused space and allows the prep and product to be in
one tray.
According to Walker, this type of package also provides
product visibility. "It enables the user to see the type of
product and its condition without having to open the unit.
It permits ease of use in the operating room by allowing
prep and insertion prior to removing the unit from the
package."
A third award that Prent received from the SPI was for
its Christmas package. Each year Prent designs and
thermoforms a Christmas package that is sent to customers as
a way to say thank you. This year the package was a plastic
origami bird with an outer package that housed it. It
required a detailed plug to create the 13 coined hinges that
are present at each fold in the bird. This design won the
"Consumer Packaging Award."
Prent designed these packages utilizing a 3-D solid
modeling surface software, then modeled and tooled them
in-house via 3-D CNC technology.
Mini-Shift
Plan
"We have a program that was started by Prent about 28
years ago called the 'MiniShift Plan'," explains Walt
Walker, vice president of operations at Prent Corp. "It has
been copied by many manufacturing companies in and around
the area but the plan that we have is still rated number
one. Not just because it offers the 'Minishift' employee a
better salary but it also provides the employees with profit
sharing and they receive just about everything that our
full-time employees receive."
The mini-shift brings in a new group of workers every
four hours to step up into the manufacturing positions Prent
has operating. What this does is bring in a whole fresh
attitude, fresh set of eyes and keeps the quality to the
level that Prent's customers have come to expect, according
to Walker.
"You can imagine what happens if you do the same thing
for 8-10 hours a day," explains Walker. "You can get lulled
into 'la-la' land. These people are a huge reason why we are
successful. Wages for this type of work are very good. If
minimum wage is 5.50, it is in excess of that by another 80
percent. You don't find this type of part-time work that
pays that well and offers employees an opportunity to work
in the kind of environment that they work in."
Long term, according to Walker, the average retention on
the first shift (from 8 am to noon) is probably around 14
years, 65 employees typically work that shift. The "B" shift
runs from noon to 4 pm and has an average employment of 12
years with 60 people working this time period. The other two
shifts (4 pm to 8 pm and 8 pm to midnight) are a little bit
more difficult to keep filled according to Walker.
"We have a high retention rate and the turnover we deal
with is usually on the lower end of the scale," says Walker.
"It is a great program. It is hard to fill full-time
positions when unemployment here is hovering around 3.5
percent and it is said that 2.5 percent is unemployable. Not
a big portion of that 1% is looking for part-time work."
Prent also offers other benefits to its minishift
employees. For one, they have the opportunity to take the
summer off to be with their kids during which Prent utilizes
college students. The same goes for the holiday season as
well. The mini-shift plan offers employees the chance to be
off 23 percent of the year if they want, Walker says.
The Mini-Shift Plan employees also have a peace of mind
when it comes to job security. "The last layoff we had, and
it was a minor one, was in 1984," says Walker. "We hang on
to our employees and work on special projects during the
slower periods. We know that typically the business will go
up. When it does pick up, we work on Saturdays and Sundays
to meet the demands and expectations of the customer. That
is what you have to do when you're in a custom
business."
Overseas
Ventures
New global manufacturing facilities in Malaysia and Costa
Rica and a strong alliance with Nelipak Thermoforming in
Ireland and the Netherlands has helped strengthen Prent's
position as a worldwide manufacturer of thermoformed
production.
Prent Corp. now has new manufacturing capabilities in
Johor Bahru, Malaysia and San Jose, Costa Rica. With a
focused attention on its core business, Prent is able to
produce packaging solutions for the medical, electronics and
consumer packaging markets in these regions. Each
state-of-the-art production facility will utilize high-speed
roll-fed pressure forming equipment designed and built by
Prent Corp.
"In the medical market, a lot of our customers have
resources in Puerto Rico," says O'Dierno. "A number of years
back, a large number of tax-free facilities were built
there. We had talked about building there at that time, but
didn't. Thank goodness, because now that tax advantage is
gone and there was this mass exit and, low and behold, where
are they landing? Costa Rica. We figure we are now in that
foundation of supply capabilities, in an area where the
likelihood of success is high. In Southeast Asia, we are
becoming very dominant in the medical and electronics
markets which is what is driving us there."
"We have a proven textbook method of conducting business
in the custom thermoforming arena in different parts of the
world," says Walker. "We are there with the technical
support, we are there with all the know-how too. We provide
everything for those ventures. They come to Janesville for
the training and we provide all the tools, from procedural
to tooling to production equipment. They provide the
wherewithal to conduct business in those countries that is
totally different from the U.S. They provide a labor force
for producing that production, which is also totally
different from what we are familiar with here. Those two
entities in themselves are extremely important to the speed
of the success with which you want a company to grow."
"If we went in on our own to Malaysia or southeast Asia
and tried to conduct business without a firm understanding
of how to communicate with ethnic and religious groups, we
would be innocently stepping on toes and being offensive,"
O'Dierno adds. "If we used a color they don't like or a
number they are offended by, we would then spend months
trying to patch that up. We are learning these things. The
relationship we have with the people there allows us to get
business much, much faster."
Prent also has an alliance with a leading thermoformer of
medical and electronic parts in Europe, Nelipak
Thermoforming, which has manufacturing plants in the
Netherlands and Ireland and sales offices in Belgium, France
and the United Kingdom. Nelipak produces and delivers parts
for any Prent customer with operations in Europe, while
Prent's global sites likewise offer manufacturing
capabilities for Nelipak's customers.
"We have a strong alliance with them and share openly
between each other," says Walker. "Even though we are
independent, we realize that this is becoming a pretty small
world."
According to O'Dierno, five years ago Prent would never
have thought it would be manufacturing outside of the United
States. "As our customers have gotten bigger, they own
sub-businesses and suddenly there is six, eight, 10 of them
and they are all over the world," says O'Dierno. "What these
customers are doing now are cooperative initiatives whereby
they focus on putting everything into one package and
leveraging a qualified supplier who can handle that
business, reducing cost by higher volume.
"Nelipak is a very progressive company and the largest
medical thermoformer in Europe with a very strong stature. I
think we got a head start on a lot of this. Now with the
progressive steps we have put in place we can put ourselves
in a positive position in Europe as well."
ISO Certified
"The other thing that affords us this ability to
streamline is our ISO certification," says Walker. "We were
the first thermoformer in the continental USA to achieve ISO
9001 in 1993 and the 23rd company overall in the state of
Wisconsin to achieve the certification. We saw the
importance of the certification and what practicing ISO
procedures would bring to our organization &emdash; the
ability for us to repeat successfully. The key here is
you're repeating high quality.
"Whatever it is that you are doing, if you practice solid
ISO procedures, your repeatability should be perfect. The
goal here is high quality," Walker adds.
"However, the real success of the organization starts
with an ownership that is continually pumping resources into
technology. The other side of that is the people who work
for the organization. From the people keeping this place
neat and clean to the people who are developing new business
around the world. Our greatest asset is our people. They all
have a focus and know what we are about and where we are
going."
