Didion International, Inc.
Designers, Engineers, Manufacturers
Company Profile - The Didion family has been in the foundry industry
since 1875. DIDION, the Machinery Company, was founded in 1974 when
Charles J. Didion, a third generation foundryman, realized the inherent
pitfalls in vibratory shakeout systems and developed DIDION Rotary
Processing Machinery. His numerous inventions revolutionized
shakeout, reclamation, sand screens, casting cleaning/cooling and the sand
blending/cooling needs of the foundry industry. The equipment was
patented internationally and the company has grown to include over 900
machines in 42 countries worldwide. The high efficiency design,
reliability and low maintenance requirements of every DIDION machine has
turned the company into the world leader in Rotary Processing machinery -
saving customers throughout the world hundreds of thousands of dollars
annually.
Rotary Equipment

Rotary
Sand/Casting Separator
Poured molds enter drum. Sand is quietly and efficiently
separated from castings, sand pockets emptied, and gates and
external cores removed.
Rotary Media Drum
Castings and sprue then enter the rotary media drum. Cling sand
is scrubbed off resulting in clean castings and returns, eliminating
or greatly reducing shot blast time. Cleaned castings are cool
enough to handle with gloves, and can be inspected prior to
grinding.
Rotary Protective
Coating Drum
Cleaned castings enter coating drum where special liquid bath
further reduces temperature for easier handling while thoroughly
coating parts with a rust inhibitor.
Rotary Lump
Crusher/Sand Reclaimers
The most efficient and reliable lump crushers/sand reclaimers in
the industry.
Rotary Dryers
Totally reliable technology for drying a full range (and sizes)
of materials. Uniquely designed to provide optimum product exposure
to incoming heated air, it also maintains temperature uniformity
with a variable Jet burner.
Rotary Sand Screens
Blends, conditions, and removes core butts and tramp metal from
return sand in one easy step.
These Machines Leave Our Competitors Shaking
It's time to quit shaking and get on a roll. Take a look at
DIDION'S line of Rotary Processing Equipment, the one's with the
fastest pay-back time in the industry. Usually within six months or
less.
This revolutionary equipment conditions green sand, no-bake and
shell moulding, while it cleans brass, bronze, ductile, gray,
malleable, or steel castings.
DIDION Rotary streamlines your operation and eliminates that
cleaning-room bottleneck. It also means no more airborne silica
dust, providing a safer and cleaner environment.
Available in ten standard sizes or custom designed for special
applications, DIDION Rotary is more efficient, economical and
reliable than vibrating shake outs, and we have the customer
testimonials to prove it.
Take the three machines pictured above. Used individually or
integrated into a fully automatic system, this equipment will clean
large or small castings, as well as, condition and screen the sand
more efficiently than any other equipment available. And, in less
time using less space
Installation is easy too, no pits or special foundations. In most
cases, all you need is a weekend. As for maintenance, your
mother-in-law could handle it. All parts are off-the-shelf, meaning
no more shut-downs and less labor.
Now you know why our competitors are shaking. They don't have a
choice. You do. Pick up the phone now and get on a roll. It's
pay-back time.
