Black oxide, zinc phosphate coatings produced on same process line

Birchwood Technologies offers a dual-process line that produces a black oxide finish using the TRU TEMP® low-temperature process and a zinc phosphate finish using the MICROLOK® MZN process on the same system.

Comprising 10 tanks with 100-gal. capacity, the line incorporates a Near-Zero™ water recycler and an ion-exchange water purifier. Both processes use common tanks and consume minimal rinse water. Both the blackening and the zinc phosphate process can operate singly or can operate simultaneously.

One operator can load and unload the system’s racks and baskets, process the loads through the line, perform general daily maintenance on the line, and produce three to four loads of finished parts per hour.
