Fiberglass Components
Advantages of Infrared Paint Curing
 Fostoria
has designed and tested a
medium
density oven for a manufacturer
of
molded fiberglass components.
Products
include: semi-tractor hoods,
earth
moving equipment hoods and cabs
for
farm implements.
They
had two problems to solve. First,
they
had too slow of a cure time using
their
current convection oven. Second, a
large
amount of paint contamination was
occurring
during the convection curing
process.
Both of these problems are
typical
of convection curing systems.
The
customer was spraying parts with
a
solvent based paint and curing them in
a
gas fired convection oven. And because
of
the air movement during the convection
process,
they realized a high amount of
contamination
and thus - a high number of
parts
to strip and refinish. Also, an
increase
in sales and the number of
different
products produced mandated the
need
for a faster line speed and an oven
versatile
enough to do many jobs.
Fostoria
designed a booster oven that
let
the manufacturer increase line speed
and
kept the finish from becoming contaminated. Using a "zone
controlled" system
of
electric infrared heat banks, they were
able
to engineer solutions to both
problems
prior to the parts reaching the
convection
oven.
Electric
infrared was able to "boost" the
product
to the proper cure temperature in only
90
seconds, compared to several minutes in the
convection
oven. This boost to curing temperature
sufficiently
tacked off the surface of the paint to
ward
off contaminates and also allowed for an
increase
in line speed to keep up with demand.
The
Fostoria design held an additional advantage for the customer. Because
the customer had a wide variety of parts, flexibility was important.
The controlled zones let the customer redistribute the oven's heating
footprint and intensity, thus conforming to individual products
without delaying production.
