Reel Coater for Ribbon or Wire

The model 412-3 is a two-chamber reel to reel web coater which deposits metal or alloys on wire or ribbon substrates by sputtering from two magnetron targets arranged in a closely spaced book array. Capacity is based upon 4" ID x 12" OD x 3" wide wire/ribbon spools. Wire diameter up to 0.035" (.9mm) may be coated at speeds ranging between 2 and 40 feet per minute depending on the coating thickness desired. Constant wire speed and tension are controlled in conjunction with other parameters which enable unattended operation for extended periods. A second chamber provides plasma pre cleaning prior to entering the sputter zone through a conductance limiting tube which allows different gas compositions and pressures for cleaning and coating.
