in the Gaps
is the process of sealing leaks in machined components made of
iron, bronze, aluminum, zinc, magnesium, steel, powder metal and
plastics, as well as alloys and ceramics. The leaks that require
sealing result from porosity caused when the components are manufactured.
Using vacuum technology or other pressure methods, Custom Industrial
Processing, Inc. fills component walls with a liquid-impregnating
material that solidifies upon deposition. The advantages of impregnation
Time and Money -- Minimizes manufacturing, machining
and assembly time and increases productivity by salvaging parts
that would otherwise be scrapped.
Chemicals and High Temperatures -- Withstands Freon
gases 12, 14 and 22, acids, gasoline, jet fuel, alkalinizes, oils,
water, steam and antifreeze, and may be used to withstand temperatures
of up to 400°F.
Vibration -- Materials used for impregnation are mechanically
"locked in" to the metal for the life of the component.
Structural and Esthetic Integrity -- Absence of surface
films or coatings retains dimensional machine tolerances and original
can also be used before electroplating, lacquering and applying
baked enamel finishes. In these applications, impregnation prevents
bleedout from acid etches and electrolytes, as well as gassing
and blistering by materials absorbed into porous areas that finishes
