Birchwood Casey’s new BC40 Tru Temp finishing system is designed to reduce finishing time and improve part quality. Using a patented, two-stage oxidation, the Tru Temp process forms a black magnetite finish on all iron and non-stainless steel parts. Operating at 200° F, the process is safe to bring in-house and easy to manage, even for untrained personnel, according to the manufacturer. The result is a non-dimensional, satin black finish that enhances the corrosion resistance and sales appeal of all types of tooling and machine components – with a 25-min turnaround time. The system is pre-engineered, sets up quickly, and is said to handle up to 2,000 lbs of work per shift. It uses seven individual tanks and occupies an area 3 × 15 feet. Tanks are ruggedly constructed of 10-gauge welded steel (epoxy painted) or ½-inch welded polypropylene and are supplied with all necessary heating elements and plumbing connections.
