Press Release Summary:
Operating with Near-Zero™ water consumption, Dual Process Line produces black oxide finish using TRU TEMPÂ® low temperature process, and fine-grained zinc phosphate coating using MICROLOKÂ® MZN process. System consists of 10 tanks with 100-gallon capacity, Near-Zero™ water recycler, and Ion Exchange water purifier. Using common tanks, both blackening and zinc phosphate processes can operate singly or simultaneously and require only one operator.
Original Press Release:
Dual Process Metal Finishing from a Single System Introduced By Birchwood Technologies - Black Oxide and Zinc Phosphate Coatings Produced on the Same Process Line
Eden Prairie, Minnesota: Metal finishers now can achieve both a high quality black oxide finish and a zinc phosphate finish using the same processing system. Safe, simple and inexpensive to operate, this innovative process line from Birchwood Technologies operates with Near-Zero™ water consumption.
Capable of two unique finishes, it produces a high quality black oxide finish using the proven TRU TEMP® low temperature process. In addition, it produces a fine-grained zinc phosphate coating using the MICROLOK® MZN process. Both finishes meet many industry requirements and finishing specifications.
Consisting of 10 tanks with 100-gallon capacity, the Dual Process 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.
Why Have Two Coating Options In A Single System?
The answer depends on the customer’s finish requirements. In the oil and gas drilling industry, for example, there is a need for both processes to finish different down hole drilling components. Similarly, job shop manufacturers with a variety of machined component projects require the specific advantages found only in each of the processes.
The TRU TEMP process operates at much lower temperatures than conventional processes, providing a high quality finish with long-term corrosion resistance without a dimensional change. It is a direct replacement for hot oxide and complies with Mil Spec MIL-DTL-13924, Class 1 and AMS 2485.
The MICROLOK MZN process is a zinc phosphate fine-grained gray finish. It provides long-term corrosion resistance along with anti-galling and break-in lubricity qualities. It complies with MIL-DTL-16232, Type Z, Class 1, 2 and 3.
System Operates Singly Or Both Processes Simultaneously
The Dual Process line offers the flexibility to operate either process by itself, or both processes simultaneously, as needed. Just one operator can handle all operations with time to spare. One operator can load and unload the system’s racks/baskets, process the loads through the line, perform general daily maintenance on the line and produce about 3-4 loads of finished parts per hour. The line can be operated on a full-time or part-time basis, depending on work-flow patterns and part demand.
