Screen Printing

    Screen Printing

    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

    • EGR Coolers, Steel Head Gaskets – Automotive
    • Fuel Cells, Recuperators– Power Gen
    • Tube & Plate Heat Exchangers – Automotive, Aerospace and Chemical

    Advantages

    Repeatability
    Screen printing is a tuned and automated process, resulting in high process consistency.

    Metering Capabilities
    Thicknesses possible of 50 to 600 μm (0.002” to 0.02”).

    Automation
    Screen printing can be part of an automated loading system – the only manual process is maintenance and reloading alloy.

    High Throughput
    Stenciling allows for braze application in complex shapes that would take much longer with dispensed paste or other methods.
