Birchwood Casey’s new BC40 Tru Temp finishing system is designed to reduce finishing time and improve part quality.
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.
