A Scene From America's Projector Carbon Center.
Final inspection before packaging
"Pre-packaging inspection... the last of 61 checks that keep our projector carbons tops!"
Jim Hoynes
From milling and blending of
raw materials to packaging of
the finished product, National
projector carbons must pass
one of industry's widest and
most rigid ranges of tests and
inspections. They are outstanding for depth of
quality control — from start to finish.
The above view in our Fostoria, Ohio, arc carbon center shows inspection No. 61 — a final overall check of each carbon before packaging for shipment to distributors.
During their many manufacturing and testing stages, National projector carbons are

baked and re-baked at precisely-controlled temperatures. All dimensions and straightness of carbons must be within thousandths of an inch. Voids or breaks in rare earth cores are detected by x-ray. Sensitive instruments measure the thickness of copper coating to assure maximum current delivery and light quality on the screen.
All the way up the 61 steps to packaging, the dominant idea at Fostoria is to produce a carbon that gives both exhibitors and patrons the best light for their money.
Today, this sound policy is fast approaching its 50th Anniversary !
