A Custom Systematic Approach from Paste Selection to Equipment to Expert Technical Support
Screen printing is a process where brazing paste is forced through a fine screen to transfer paste to a part. The screen acts as a stencil that only transfers brazing paste to the desired areas of the part. In the process, a squeegee passes over the screen stencil both forcing the paste through and preventing the waste of excess material. The stencil allows for the printing of complex patterns on the base material being brazed.
Screen Printing Applications
Screen printing is a tuned and automated process, resulting in high process consistency.
Thicknesses possible of 50 to 600 μm (0.002” to 0.02”).
Screen printing can be part of an automated loading system – the only manual process is maintenance and reloading alloy.
Stenciling allows for braze application in complex shapes that would take much longer with dispensed paste or other methods.
Wall Colmonoy Aerobraze’s Oklahoma City facility uses screen printing to support high volume production of fin and plate heat exchanger cores. Watch video below:
