This machine shop in Midland
Odessa area has three different anodizing areas in 3
consecutive areas that are all adjacent to each other.
One area does only Type III hard anodize. The next
area over from the hard coat area does only Type II clear
anodizing and nothing else. The last area does only
Black anodizing. There is a 20,000 square foot CNC machine shop
floor located in the main indoor only building. The
anodizing area in the overhead door section and operate
permanently from here. This Type III hard coat, Type
II clear anodizng for boat parts, and Type II black
anodizing for firearm parts to service the $409,000 to
$450,000 in anodizing service work they use to send out
until they started their own anodizing. The owner of this
CNC machine shop
was sick and tired of relying on anodizing shop to anodize
his parts and literally had to FLY THE PARTS to an anodize
shop in El Paso Texas. That was the closest shop that
could handle $400,000 to half a million dollars in
anodizing. This owner had to fly the parts in his
eight seater plane from Odessa - Midland Airport to El-Paso
Airport three times a week to either drop off or pick up.
That is insane to fly one's own plane to drop off parts to
Now the shop owner is able to control this lead
time as well as anodize quality. He could care less
about saving money but this shop was able to pay for itself
in about 9 months of anodizing services he no longer sent
out. Now the half a million dollars in anodizing work
cost the owner $8,500 in chemicals and $1,500 in
consumables. He does have labor for three guys which
is the head coating guy at $20/hour, newly trained anodize
$18/hour guy who runs the anodize systems, and a $13.50/hour
helper to help both of these guys get loaded and unloaded.
The anodizing line only runs 8 hours on Monday, eight on
Wednesday and will run for 5 hours on Saturday to finish up
This line was built to anodize the vast array of custom
machined boat parts fabricated at this machine shop.
All the parts are Electropolished and then anodized with a
clear bright finished.
Above left is
the aluminum soak tank and an aluminum brightener tank.
The picture to the right is the Desmut AL tank. Behind the tanks on the right is a
DI/RO water system for replenishing evaporated water in the
process tanks. This negates the need for buying
distilled water all the time. You can also see this same DI/RO water
system below too.
directly above and below are
pictures of the anodizing tanks. The bussing is done
with solid 6063 aluminum and the cathodes are made from 1000
series high purity aluminum. The clamps on the center
bus bars are used to hold down the anodizing racks and
secure the parts to the anode bus bar to insure proper current transfer
to the anodize parts.
The bottom middle and the bottom right is the Mid Temp
Sealer tank. This is a non boiling sealer used in most
of our commercial anodizing applications. It requires
heating much lower than hot seals, therefore it is more
efficient and safer to use.
the Decorative Anodizing tank and the Mid Temp Sealer is
filtered with Flo King filter systems. It is the black
unit with the blue top sitting in the back of the tanks.
The filter system is used to
clean the tank solution, therefore insuring a long and trouble free solution life.
Above is a fume scrubber for venting the Bright Dip
tank. Bright Dip AL has a very distinct ordor to it
and most users do not like their shop smelling like Vinegar
and oil times 20 so they use a fume scrubber to remover
odor. At the above right is the Type III
anodizing tank with our standard 99.7% high purity custom
extrusion 1100 aluminum. This Type III tank is
used for no dye hard coat. The other pictures below are some other miscellaneous pictures from the shop
which is the rectifier being wired by electrician
The next photo is an HVLP pump to drive mix sparger.
Above is a
waste water evaporator used for Bright Dip and aluminum
chromate only. The system at bottom is used for all
other steps. It is a fully automatic, yet simple
waste system that has 3 station treatment procedure.
Neutralization of electric charge in waste water, adjustment
of pH to between 6.4 to 8.2 pH reading, add metal reducer,
and finally add a metal coagulating chemical to make metal
very easy to filter because it has precipitated out of the
rinse water. which runs automatically then a sewer
discharge through a lime stone media filter. Hope you enjoy the tour.
