New Black Oxide Finishing Line Operates At Low Temperatures and Finishes Parts In 10 To 15 Minutes With No Pollution

Eden Prairie, Minnesota: Birchwood Casey's new BC40 TRU TEMP(TM) finishing system produces high quality black finishes on iron and steel components in just 10 to 15 minutes.

This seven tank line utilizes a patented two-step chemistry that produces a true black magnetite finish of .000020" thickness, satin black in appearance and equal to that of conventional black oxide.

Important process differences make the new Birchwood Casey BC40 system a major improvement over hot oxide. The BC40 TRU TEMP system operates at just 190°F compared to dangerous hot oxides that normally operate at 290°. The severe splattering and boil over hazards are not present.

Because the TRU TEMP process contains no EPA regulated chemicals, there is usually no need for waste treatment equipment. In most sewer districts, the rinse waters are considered to be sewerable as non-hazardous effluent. The initial capital investment, therefore, is only half that of other blackening process systems.

The BC40 TRU TEMP system is pre-engineered, sets up quickly and operates easily. It utilizes seven individual tanks, each measuring 16 x 24 x 24 inches deep, and occupies a footprint of just 3 feet x 15 feet. Tanks are ruggedly constructed of either 10 gauge welded steel (epoxy painted) or 1/2" welded polypropylene, and are supplied with all needed heaters and plumbing connections. A detailed owner's manual guides the user through assembly, charging with chemicals, startup, testing and troubleshooting - all with technical support from Birchwood Casey.

The process is ideal for virtually all dimensionally critical parts including power drive components, gears and machine parts. Also important, the BC40 TRU TEMP process meets military specification MIL-C-13924C Class 1.

In this era of intense productivity scrutiny, the BC40 TRU TEMP in-house system provides the owner with complete control of quality, scheduling and cost of finishing operations, all of which are absent using outside vendors.
