Move Projects Forward. The Best News Yet for Process and Quality Engineers

Hunter Brankamp

Think about your company’s manufacturing operation.

Now, think about fixing your adhesion problems simply by knowing a single number...

  • Finally push product development past key sticking points
  • Fix long-standing, seemingly unsolvable bond-line failures
  • Reduce scrap, rework, and production downtime to all-time lows

Accomplishing these is a reality for process and quality engineers in manufacturing across all industries.

While getting the number is as simple as a push of a button, the real key for teams is to:

Know what the number means in terms of changing and ultimately improving your process


So, how does it apply to the factory floor?


As a general rule, the lower the number, the higher the quality of the surface...and the stronger adhesion will be.


Let’s illustrate these points as we cover a few examples where customers expectations didn’t match up with the measurement:

solvent wiping aluminum

The process: Solvent Wiping and Abrading Aluminum

  • You’ve just solvent cleaned an aluminum surface.
  • Your average measurement number is 56 degrees.
  • You “know” that abrading an aluminum surface helps promote stronger bonds. However, after using sandpaper on the surface, this is not the case…your average measurement has increased to 79 degrees.


flame treatment of polymers

The process: Flame Treatment of Polymers

  • You’re analyzing thermoplastic parts before and after flame treatment.
  • The pre-treated surfaces show an average measurement of 81 degrees.
  • You “know” that flame treatment better prepares polymers for printing,  so you expect the number to decrease. However, after flame treatment the number is 92 degrees.


preparation for flame treatment

The process: Hand-Prepping Peel-Ply Composites

  • You’re prepping a peel-ply composite surface in an ultra-clean room for adhesive bonding.
  • You’ve determined that your freshly peeled composite surface yields an average number of 36 degrees.
  • The peeled composite is left out overnight, totaling 10 hours of exposure time. When you come back in the morning to check the surface before bonding (and you should be), the average number of the composite is 58 degrees.

See the common thread?

These are real customer instances where confusion occurred without possessing a full understanding of what’s affecting surface quality. If that's the case, problems will invariably persist.
