What is Tru Temp® Black Oxide System?
Utilizing a unique two-stage oxidation (patent pending), the Tru Temp® Black Oxide process forms a black magnetite finish on all iron and non-stainless steel parts. The Tru Temp process operates effectively at much lower temperatures than ordinary black oxide- 100 degrees lower, in fact! The result is a protective black finish- 0.000020" (1 micron) thick, with an attractive satin black appearance equal to that of regular black oxide.
Safe. Easy to Operate. No Boiling Chemicals
Let's face it. The 290°F operation of ordinary black oxide is scary hazardous! The typical bath contains 6-8 pounds of caustic soda per gallon, and is prone to boil-over and splattering. This creates a worker safety nightmare! By comparison, the Tru Temp bath is much milder and cooler -- severe hazards are just not present.
Fast. Cost Effective Process
The Tru Temp Black Oxide reaction takes only 6-10 minutes, compared with 20-40 minutes for ordinary hot oxide. As a result, the entire process is shorter and the work flows through faster, resulting in lower labor costs. Since labor is the largest single cost factor of any blackening system, your overall finishing costs are reduced significantly.
No EPA Regulated Chemicals
The Tru Temp Black Oxide system contains no heavy metals, carcinogens or other EPA regulated materials. The rinse water effluent from the process line is generally sewerable, usually with pH adjustment only. (Check with your local authorities)
A Whole New Option for Parts Finishing
If you now own a black oxide system, or send parts outside for blackening, the Tru Temp in-house blackening system provides a better option for you. You can regain control of your black finishing, without endangering your employees or compromising the quality of the black finishes. The process meshes easily with your Quality and Inventory systems by giving you control over the quality, scheduling and cost of your finishing operation.
