|An automated Tru Temp black oxide finishing system can potentially reduce part finishing costs up to 75 percent. |
Automated, pollution-free, lowtemperature black oxide finishing systems from Birchwood Casey are reducing finishing costs by as much as 75 percent for two of the company’s customers. One Tru Temp CNC automated system is being used for finishing motion control and power transmission components, while a second Tru Temp system is finishing firearmrelated components. Both systems employ the latest automated finish technology for environmentally friendly, fast part finishing without the addition of labor.
“Manufacturers are striving to improve quality and lower costs without using polluting processes, and one primary area of interest is in metal finishing,” reported Mark Ruhland, vice president of Birchwood Casey. “The latest automated CNC Tru Temp system incorporates a programmable hoist that moves components through the 200-degree F. black oxide process in a 28-minute cycle from start to finish.”
He added that the safe and simple process contains no EPA-regulated compounds and usually requires no waste treatment of process rinse waters. The CNC-controlled process line produces consistently high-quality, black oxide finishes with minimal labor input, to streamline workflow patterns and smoothly mesh with ISO and JIT programs. Capital costs are modest, with fast payback schedules.
