Filling in the Gaps

Impregnation 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 are:

Saves Time and Money -- Minimizes manufacturing, machining and assembly time and increases productivity by salvaging parts that would otherwise be scrapped.

Resists 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.

Withstands Vibration -- Materials used for impregnation are mechanically "locked in" to the metal for the life of the component.

Maintains Structural and Esthetic Integrity -- Absence of surface films or coatings retains dimensional machine tolerances and original color.

Impregnation 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 have sealed.

Applications:

• Water & Fuel Pumps
• Castings Gas & Steam Fittings
• Powder Metal Parts
• Plastic Molds
• Aircraft & Aerospace Fittings
• Carbon & Metal Seals
• Ceramic Parts
• Electronic Components
