EDCOR sits on a 3-3/4 acre plot in a 10,000 square foot building, right off of
National Parks Highway in Carlsbad, New Mexico. All of EDCOR’s manufacturing,
sales, stocking and shipments occur at this location.
Let’s start with your order. EDCOR has a sales staff which includes a few technical
engineers. Once your order is placed and in our system, it moves on to the
design engineers or into the production schedule.

Our engineering department has a number of DELL workstations used for design,
schematics and mechanical drawings. All of EDCOR’s data is kept on our server
that is backed up daily. We also keep hard copies of all transformer designs in
fireproof safes. Design data is very important to us.

 |
Production begins by getting the material ready for the order. We have a large selection of
bobbins that range from 1/8” by 1/8” cores up to 1-1/2” by 4” cores, PC mounted,
with terminals or standard leads. EDCOR also keeps a hefty supply magnet wire on
hand from 44 gauge up to 16 gauge.
gauge.

The transformer is wound on CNC (computer numerical controlled) winding machines or
on a more manual winding machines depending on the quantity of the order and
complexity of the design. The CNC winding machines give more of a consistent
winding. But, we have winders here that have been winding for over 30 years and
can out wind our CNC machines with no problem.
|
 |
 |
After winding, the transformer is moved to one of our finishing stations. The station
depends on how the unit is to be finished; if it takes leads, terminals or is PC
mounted. All of the solder that EDCOR uses is lead free and RoHS compliant.
|
|
From finishing, the transformer proceeds to stacking. EDCOR uses a number of
different cores. We primarily use M6 steel for our transformers, but also use
nickel and powder ferrite for specials and customs. We have a number of stacking
machines that stack from 3/16” up to 1-1/2” EI steel cores. All nickel cores are
stacked completely by hand. Stacking machines make stacking a transformer easier
and quicker, but they do not get the stack tight enough. This is where our
finishing stackers come in. They finish the stacking of the transformer, put in
any keepers and make sure the transformer core is tight enough. Finally they put
on any type of mounting hardware, such as channels or brackets.

Next, the transformer moves to the varnishing room where it is dipped in an electrical
varnish and set out to air dry to a nice clear finish. EDCOR does not bake any
of its transformers in an oven to dry the varnish. Baking produces an ugly,
yellow, crusty finish. That is not acceptable for an EDCOR product.
|
|
The transformer then arrives into the testing department. Over the years, EDCOR has
invested in wide variety of test equipment for the explicit purpose of creating
the best transformers for our clients. Depending on the transformer and
specification, it can be tested in a number of different ways. Our test
equipment ranges from scopes, meters, power supplies, amplifiers to our computer
run Audio Precision test equipment. We can plot THD, noise, frequency response,
ect. Many of our larger clients require recorded records.
|
 |
 |
After testing, the last steps are labeling and shipping. EDCOR ships out
transformers all over the world. Large amounts to Asia, Europe, the Middle East
and of course North America, just to name a few.
|
|
To give you an idea of how many transformers EDCOR produces, in the first six months of
2009, we have already shipped over 19,000 units, and that is only in audio
transformers!

Another aspect of EDCOR you may not know is that even though we are known for our blue
transformers, we are also green. EDCOR recycles much of its waste and used
material. With the large amount of magnet wire we go through each week, we get a
good amount of empty plastic spools. We also get plenty of cardboard and
discarded steel. And yes, even some of our transformers don’t make it out the
door and the copper is saved for recycling. EDCOR also offers bottled water to
all of their employees and the empty bottles are recycled. Most of EDCOR’s
recycling goes to the Rainbow Recycling Center. This recycling center is run by
CARC, Inc. which provide services for people
with special needs that enable them to be active, productive citizens.

Lastly, we cannot forget one of the most import jobs at
EDCOR: security. EDCOR employs a security officer that is top notch in her
field, she keeps a close eye on everything that goes on here. Her name is Spooky
and she has taken up the position of watch dog.

Well, that was just a little gimps inside EDCOR Electronics.
