Original Press Release:

Birchwood Technologies Introduces BC40E TRU TEMP Process Line as a Low Cost Entry System for In-House Black Oxide Finishing

Eden Prairie, Minnesota: Manufacturers contemplating taking Black Oxide finishing in-house now have a low cost entry option with the Birchwood Technologies BC40E TruTemp finishing system. The seven-tank process line, with full black oxide capabilities, comes complete with tank system, heaters, plumbing connections, tank lids, and chemical products, all for the low price of $9900.

The new BC40E TRU TEMP system is pre-engineered to set up quickly and operate safely. It utilizes seven individual tanks, each measuring 16 x 24 x 24 inches deep (ID), and occupies a footprint of just 3 x 13 feet. The tanks are rugged and virtually unbreakable, manufactured of heavy weight, high-density polypropylene and polyethylene.

Setting up an in-house blackening line is now more economical than ever. Easy to learn and safe to operate, these lines produce high quality black oxide finishes and can often be operated by workers in adjoining CNC, screw machine or parts washer cells, without adding new employees. An in-house BC40E TRU TEMP line usually pays for itself in a very short time.

Using the patented Birchwood Technologies TRU TEMP black oxide process, the new BC40E tank line provides the owner with all of the advantages of an in-house system — a high quality, Mil-Spec compliant, black oxide finishing capability with a 25-minute cycle time. It provides ultimate control of quality, scheduling, and cost of finishing operations that is not available with outside black oxide services.

The TRU TEMP process contains no EPA regulated chemicals, so there is no need for waste treatment. The rinse waters are generally sewerable as non-hazardous discharge. The initial capital investment is a small price for all the benefits this system offers.
