Think about your company’s manufacturing operation.
Now, think about fixing your adhesion problems simply by knowing a single number…
What do both of these statements about surface adhesion have in common?
- “We need to measure surface quality of the teeth on a gear to make sure the coating stays on.”
- “We need to make sure the coating on our tubing is uniform, but we can’t measure a curved surface with our current surface testing method.”
What could happen in 10 minutes?
Well, if you work to improve a manufacturing operation, you know that means quite a bit…
Water break testing. Dyne pens. Goniometer. No method at all.
The search for a reliable, repeatable, objective method (i.e. not based on opinion) for measuring surface readiness in manufacturing was a search all too common among our current customers, and these methods are the most commonly tried and (formerly) used among them.
Achieving great adhesion in manufacturing comes down to surface preparation (we call it “Clean to a Number”) and optimal surface prep is the difference between an average product…and an industry-leading one.
But getting there means having an objectively quantified understanding of the top 3 molecular layers of your material surface.
Did we just say “top 3 molecular layers?”
On May 21-24, BTG Labs heads back to Long Beach, CA but this time for the SAMPE 2018 Conference & Exhibition.
Recently in Long Beach for AeroDef, one of the aerospace and defense industries’ most widely recognized conferences, BTG Labs now contributes to this tradeshow that features “the latest technologies and research advancements in the industry.” Maybe you’ve heard of a little instrument called The Surface Analyst?
Performing any kind of inspection on small parts can be difficult. When measuring for surface cleanliness, accessing small parts can be even more challenging, especially when measuring on the factory floor.
With the Surface Analyst, measuring surface cleanliness on small parts has never been easier. This handheld instrument is fast, easy, accurate, and non-subjective allowing for precise measurements, right on the factory floor.
With specialized measurement heads and a tether to allow access to small parts, manufacturers can verify surface readiness to bond, paint, clean, coat, print, or seal. The Surface Analyst optimizes manufacturing, repairs, and maintenance. …Read More
BTG Lab’s recently held another successful webinar. Hosted by Products Finishing and presented by Dr. Giles Dillingham, the webinar emphasized the importance of monitoring cleaning processes and explored different ways to measure surface cleanliness.
In the webinar, Dr. Dillingham discusses measuring surface cleanliness as a way to quantify cleaning processes. By measuring the success of cleaning processes, manufacturers can determine the ideal solution for their application.
Precisely evaluating cleaning processes with water contact angle is a fast, easy, accurate, quantitative to way to gain ensure consistency and precision on the factory floor.
Challenges often arise when verifying critical surface processes on the factory floor when measuring hard to reach areas and varying angles. The Surface Analyst conquers those challenges with the unique ability to measure on vertical surfaces, which include assembled parts and hard to reach spots. This allows for easier surface analysis on the factory floor.
A few examples of the Surface Analyst’s ability to measure on vertical surfaces on the factory floor:
- Airplane wings prior to bonding, painting, and repair
- Canopy of jet fighters after cleaning
- Wind turbine blades prior to bonded repair
- Silkscreen bottles post flame treatment
- Ship hulls prior to painting and bonding
- Interior of automobile headlights prior to application of anti-fog coating
- Windshield bond lines prior to sealing
- Class A paint surface for decals applications and reapplications
- Measuring appliances after metal cleaning and prior to power coating
Top aerospace manufactures recruit state-of-the-art equipment to ensure precision and perfection. One thing the best of the best have in common: the Surface Analyst. BTG Labs first engineered the Surface Analyst through an SBIR (Small Business Innovation Research) grant to collaborate with the USAF (United States Air Force). Born out of necessity, the instrument was engineered to verify a surface’s readiness to adhesively bond fasteners.
Today, the Surface Analyst is written into Lockheed Martin specifications for fighter jet manufacturing; it played a major role in the development of the F-35; and its expertise is trusted on all factory floors of top aerospace manufacturers.
While the Surface Analyst use has spilled outside of the aerospace box, BTG Labs remains closely tied in the aerospace industry and that is why you will find us at AA&S 2017. Taking place May 22-25 in Phoenix, Arizona, The Aircraft Airworthiness and Sustainment Conference attracts leaders of the aerospace industry from around the world.
Manufacturers are all too familiar with the challenges of getting a bond to stick and hold. The success of a bond relies on the surface created prior to that bond, so, monitoring and measuring surface processes is the only way to know that the surface is ready to bond reliably.
BTG Labs’ President Tom McLean and Sales Engineer Lucas Dillingham presented during Plasmatreat’s Open House on the 4 Surface Fundamentals for Successful Bonding in Manufacturing. They presented to industry leaders who can easily relate to bonding and cleaning issues. The presentation was such a success that BTG Labs decided to turn it into a webinar.
Challenges with establishing a strong, reliable bond, when painting, coating, sealing, or printing are tied into the surface preparation process and the ability to monitor that process. This presentation focuses on the bond surface and what it takes to bond properly to that surface. There is also a comparison of various cleaning methods using contact angles taken with the Surface Analyst.
While other monitoring processes such as dyne and water break fail to provide quantitative insight, monitoring cleaning processes with the precise and quantitative Surface Analyst tells the user, objectively, whether the surface is properly prepared to hold a reliable bond. …Read More
