Compared to microcracked systems, this process from Enthone Inc., West Haven, Conn. (enthone.com), is said to lower operating costs by reducing the number of necessary rinses.
The DUR-NI 4000 process uses a Fuhrmann Test that accurately counts micropores on the chrome surface immediately after parts are plated. Pore count is a key indicator and predictor of corrosion performance. The Fuhrmann Test eliminates the need for CASS testing as the sole control for determining acceptable corrosion performance. The Fuhrmann Test lets users quickly intervene during production and predict subsequent CASS Test results. Traditional nickel processes do not include such a test, thus process corrections and adjustments made after CASS testing can shut the line down for up to a 72-hr while a second CASS test is run.
The DUR-NI 4000 is for automotive OEMs and Tier-1, 2, and 3 plating shops and is also well suited for many decorative applications, such as hardware, lighting, and plumbing accessories.
