ENTRY
The
Incoming Coils and Paints
are tested for the adherence
to the specifications
The coils are then loaded
on the uncoiler to begin
with. The coils then pass
through the sticher where
the end of the earlier
coil and the coil following
it are stitched together
. This ensures that the
material is running continuously
on the line without any
stoppage or wastages.
The accumulator further
ensures that the line
is feeded with the requisite
material to ensure the
continuity.
PRETREATMENT
The
coils are then passed
through the degreasing
, rinsing and pretreatment
tanks to ensure that the
surface is clean and pretreated.
This is the place where
the coils are washed ,
brushed to ensure that
most of the oil or the
foreign particles are
done away with . The coils
then undergo the pretreatment
process. The basic purpose
of the pretreatement and
the degreasing is to make
the surface of the coil
ready to accept the further
coating system. The pretreatement
chemical & other chemicals
are checked for the concentration
and the adherence to the
specification on a regular
period. The pretreatment
is the heart of any coating
process and it ensures
the longevity of the Product
.
PRIMER COATING
The
Pretreated coils are then
sent to the primer coating
machine for the primer
coating . The primer is
applied mostly on one
side . But if the specifications
demand the primer can
be applied on both sides
as well. The wet primer
coated coils are then
baked in the oven . The
temperature zones of the
ovens are set in such
a manner that requisite
Peak metal temperature
is attained . The coils
are then cooled with the
cool water spray to ensure
the temperature of the
coils is brought down
to ambient levels. The
coils are further squeezed
to ensure that the water
traces are not left on
the coils. The coils are
further dried with Air
blowers.
FINISH
COATING
The
Coils are then applied
with the final wet coat
on top side on the final
coating machine with the
requisite system , finish
and colour . Simultaneously
the coils are applied
with the service coat
or the backer coat on
the back side. The unique
reverse roller coating
technology ensures that
the paint is applied uniformly
& smoothly on the
coil surface . This ensures
the long life , non Peeling
, best quality product
is available to the client.
The wet finish coated
coils are then baked in
the oven . The temperature
zones of the ovens are
set in such a manner that
requisite Peak metal temperature
is attained . The coils

to ensure the that water
traces are not left on

further dried with Air
blowers.
EXIT
The
coils are then passed
through the accumulator
. The accumulator here
also ensures the continuity
of the material and no
stoppage is caused. The
accumulator here ensures
that the material is stored
within at the time of
the coil change. When
the joint of the two coils
come , the shear cuts
the coil at the joint
and the second incoming
coil is wound on the second
coiler . The process remains
continuous . The material
is finally wound on the
first coiler is sent for
packing if okayed by the
quality control department.
