For example, two methods of joining the fins to the tubes are available. Brazing paste may be applied either to the fin tips or to the tubes - each requires a slightly different configuration. Setup costs also vary depending on whether the plant is designed for low or high volume. The CuproBraze process also provides a high degree of flexibility in the manufacturing process allowing a variety of radiators of different sizes and mass to be brazed with minor adjustments. The wide safety margin between the brazing temperature of brass as well as the forgiving nature of the process results in higher output and lower scrap rates.
Less waste means lower production costs.
Initial costs for adopting CuproBraze technology according to four different scenarios are presented. The costs listed do not include engineering, design or site-preparation. These cost projections do not attempt to quantify the value of the quicker commissioning and set-up time of the CuproBraze furnace, which mean the line will be producing product sooner than the aluminum process. Additional equipment, depending upon the actual configuration, includes a fin tip or tube coating machine, slurry coating machine and other machines as necessary. An existing Nocolok line can be converted to a CuproBraze line at minimal cost because the furnace for brazing aluminum can be used for the CuproBraze process.
