Finishing
Services (Ypsilanti, MI) was founded in 1975 as a phosphate coating
facility, with emphasis on heavy zinc and manganese phosphate application.
Seven years later, with the economy in recession and auto sales
weak, the company determined that there was a need to expand the
range of coatings offered and installed a highly flexible multi-process
line for process development and the plating of small production
quantities. That line, which is still operating today, has provided
the product and process development capability that has fueled most
of Finishing Services growth during the past two decades.
Mitchell
Marsh, president of Finishing Services, now directs a diversified
company that specializes in projects that involve technical coatings,
custom fixturing and tight controls. Today, in addition to a fully
automated phosphate line capable of processing more than 25,000
lb of product per hour in several different phosphate formulations,
the company operates automatic barrel and rack lines for tin-zinc,
zinc-nickel, tin and electroless nickel. While phosphate coatings
remain a major component of the companys business, the application
of alloy coatings and electroless nickel has provided a substantial
portion of its nearly 15% annual growth during the past ten years.
Mr. Marsh believes the reason for this growth has been good people
who have intuitive skills about their work and a corporate culture
that values lean thinking, flexibility and innovation.
The
constant with our company during the past years, said Mr.
Marsh, is our effort to improve processing methods and processes
and to meet the evolving needs of customers. Finishing Services
prototyped several new alloy coatings, which became the companys
growth engine in the 90s. Now, according to Mr. Marsh, the goal
is for the auto companies and their suppliers to be hexavalent-chromium
free by 2007. Once again, he said, were
at the forefront, this time with trivalent topcoats and chrome-free
conversion coatings.
The
equipment necessary to achieve these objectives is the easiest part.
Finishing Services founder was, first and foremost, an equipment
designer and modifier, with specialized expertise in hydraulics
and material handling. For automated chemistry and replenishment
technology, weve always relied on the best vendors out there,
but equipment was an in-house thing, said Mr. Marsh. Building
lines and fixturing are what we do, and over the years, this has
given us a lot of flexibility.

Services also seeks flexibility in its choice of chemistry. There
have always been pressures from some customers to buy from one chemical
vendor over another, said Mr. Marsh, but we think our
competitive advantage has come because we are not tied down by names
and hard demands and choose vendors by merit instead.
In
heavy zinc phosphate work, for example, most specifications are
not product-based but performance-based, and thats just the
way we think it should be. Phosphate processing is still one of
our mainstays, and we believe that it continues to have substantial
growth potential. The market has changed over the years, and today
our growth in this coating is directed primarily toward specialized
formulations and applications.
We
rely heavily on our suppliers to determine whats guarantee-able
to our customers, said Mr. Marsh. Chemical suppliers
are either producers or copy-cats, and only a few understand enough
to effectively partner with you. Knowledge, like the coatings themselves,
should not be just what you see on the surface.
Previous
Partnership
When
Finishing Services started looking for a zinc phosphate supplier,
the possibilities were manyand often just a few tanks away.
Two of the largest zinc phosphate suppliers already sold the company
other products. A third, Heatbath Corporation (Springfield, MA),
had the advantage because it had partnered successfully with Finishing
Services on a recent critical project, the outcome of which had
proved highly beneficial from both a performance and cost standpoint.
The
projects goal had been to find emulsifiable oil that would
exceed automotive salt spray requirements. Heatbath recommended
its advanced Lab Oil 100. It met the specifications, offered important
advantages in terms of process control and was flexible in how it
could be used.
Tests
in our lab showed we could run Lab Oil 100 at higher temperatures
and lower concentrations, and get longer bath life and greater consistency.
What a combination! Plus, we were able to eliminate one oil tank
entirely, said Mr. Marsh. Finishing Services had previously
operated three oil tanks: one each for dry-to-the-touch, medium
(72 hr salt spray) and heavy (150+ hr salt spray).
By
replacing the old system, the company eliminated one tank. Now,
said Mr. Marsh, we run one tank (dry-to-the-touch) for the
72-hour specification, and the heavy oil is used wherever we need
more than 150 hours. (In fact, emulsions of Lab Oil 100 on
zinc-phosphated steel have performed in excess of 240 hours of salt
spray exposure, per ASTM B-117.) Due to the consistent results obtained
with this product, Finishing Services no longer found it necessary
to retain parts until completion of the 72-hour salt spray testing
cycle, an added benefit that has shortened lead times and is appreciated
by all of its customers.
The
product is also highly emulsion-stable to alkaline or acid contamination
as encountered in phosphating cycles. This is in marked contrast
to traditional water-soluble rust preventives, which have very poor
stability with alkaline or acid contamination.
Based
on the success of Lab Oil 100, Finishing Services began extensive
test processing with Heatbaths zinc phosphate technology.
In January of 2000, the decision was made to install Heatbaths
Phos Dip 1263 heavy zinc phosphate.
Phos
Dip 1263 was engineered for heavy zinc phosphate coatings of approximately
2000-mg/sq ft on ferrous surfaces. It provides maximum corrosion
performance and exceeds all known government, automotive and appliance
specifications for zinc phosphate coatings.
Phos
Dip 1263 is highly concentrated, has a high tolerance for iron in
solution and produces exceptionally consistent results. Sludge formation
is minimal, so process downtime and maintenance are less of an operations
issue than with conventional zinc phosphates.
Installation
of Heatbaths zinc technology was completed a few months after
the installation of Lab Oil 100. The zinc phosphate line is,
by definition, a large capacity operation, said Mr. Marsh,
so it was extensively tested before we transitioned our customers
over to it. Over time, all of Finishing Services performance-based
projects were transitioned to the Heatbath chemistry. With
this type of process, said Mr. Marsh, you really cant
take chances with the equipment or your chemical supplier. You need
vendors wholl be there when you need tech support and who
are able to offer answers in real-time.
Notably,
he added, line operators today play a far more visible role
than even a few years ago. We often bring the customer to see our
operation, so he has the best possible understanding of the process.
Customers often meet the operator running the parts, creating an
expanded level of interaction thats new and positive. It helps
when the operator has ownership of his work.
Finishing
Services workers are extensively cross-trained in an effort to further
expand flexibility for the company, the workers and the customers.
That kind of cooperation has also produced better customer service
and a customer base that spans from New York State to areas west
of Chicago. Weve proven that the disadvantages of shipping
and distance can be overcome by high quality, and exceptional service,
said Mr. Marsh.
Today,
the companys plan is to grow its zinc phosphate business,
to evolve new applications for phosphates, and to expand replacement
alternatives for hex chrome. It is also modifying one of its barrel
automatics, doubling the capacity of its wastewater filter press
and making other upgrades.
The
recent business climate, which has disadvantaged some, has been
great for us, said Mr. Marsh. The reason is that, when
industry activity slows, buyers have the time and the motivation
to look for ways to save costs and evaluate new products. Its
the perfect environment for us. There are more buyers willing to
listen and consider alternative processes than youll ever
find in one of those so-called great years!
And
when times do get better across-the-board, we believe customers
will do what they did after the last business downturn: stay with
the supplier whos proven that he and his vendors have what
it takes to get the job done.
