Enhance Lean Manufacturing, Reduce Costs With 100 Gallon
TRU TEMP® In-House Black Oxide System

Eden Prairie, Minnesota: Reduce part finishing costs using the 100 gallon TRU TEMP® in-house black oxide process. This low temperature black finishing system optimizes quality, efficiency and safety.

The new TRU TEMP process is an ideal in-house substitute for dangerous 290°F hot oxide processes. Operating at only 190-200°F, TRU TEMP is safe, operator friendly and eliminates the severe hazards of a boiling tank.

With a fast 18 minute blackening time, this process forms a durable, black magnetite finish of .000020 inch thickness equal to that of black oxide. The in-house process streamlines part movement, provides better control of finished part inventory and enhances ISO accountability. Perhaps best of all, it gives the user a "same-day turnaround" capability to satisfy key customers and fill rush orders - without raising finished inventory levels.

Satisfying Mil Spec DTL 13924D and AMS 2485, the TRU TEMP process contains no EPA regulated metals. Rinse waters are sewerable without waste treatment. Because the process requires no effluent treatment, the initial capital investment is only about half that of other blackening systems. Many parts can be processed for a chemical cost of only about $.02-.05 per pound.

The TRU TEMP 100 gallon line is supplied as a completely pre-engineered process line for fast setup and use. The system utilizes seven individual tanks, each measuring 24 x 40 x 28-1/2 inches deep with a 100 gallon capacity. The complete system occupies a footprint of 4 ft. x 22 ft. Tanks are ruggedly constructed of either 10 gauge welded steel (epoxy painted) or 3/4 inch welded polypropylene, and are supplied with all necessary heaters and plumbing connections.
