In 2014, a large manufacturer of automotive exteriors and interiors encountered a problem consistently adhering paint to their dashboards due to an inappropriate use of their flame treatment.
Flame treatment is a popular and notable procedure that can successfully modify the surface chemistry of a polymer, readying it for adhesion. Although flame treatment is an effective solution, determining the amount of treatment can be a delicate procedure. The over-flaming of these highly sensitive polymers can lead to polymer reorientation due to localized melting and ultimately, destruction of the surface.
In this case, however, the manufacturer was not utilizing flame treatment to monitor their surface cleanliness. Instead, they used it to deflash excess material on the edges of their dash boards. The edges of the dashboard were being over-flamed, hindering the polymer’s surface adhesion ability. This, in turn restricted paint from correctly adhering to the edges of the dashboard. The company needed a way to determine the appropriate amount of flame treatment.
BTG Labs is gearing up for Earth Day; after all, we proudly manufacture an instrument that is valuable in a variety of industries from aerospace, automotive, packaging, and even renewable energy. It’s also pretty eco-friendly.
The Surface Analyst™ improves the manufacture of renewable energy equipment including solar panels, wind turbines, and electric cars. BTG Labs also works with start-up companies creating brand new technologies for renewable energy. The Surface Analyst measures water contact angle to ensure that surfaces are ready to bond and withstand environmental stresses without failing. Its precision, portability, and ease-of-use allows for its implementation on the manufacturing floor as well as in the field for repairs and maintenance.
Technicians use it for repairs on wind turbines in the field; solar panel manufacturers value its precision when bonding dissimilar materials to withstand weathering; and electric car companies use it to guarantee paints, bonds, seals, and coatings will stick reliably. New applications for improving renewable energy manufacturing using the Surface Analyst reveal themselves constantly.
The Surface Analyst also contributes to conservation in every manufacturing field. Because it offers manufacturers precision and is non-destructive, it cuts down significantly on waste material. The Surface Analyst replaces dyne inks which hold harsh chemicals—including teratogenic chemicals—that are hazardous to the user and the environment. Because of this, dyne cannot be used to test on the actual material and often requires a coupon of the material that has been cut off or specifically designated for testing, off the assembly line. Dyne is also highly subjective and leads to inconsistencies in manufacturing, causing rework and failures, which in turn, means more waste. On the other hand, the Surface Analyst uses highly purified water so it’s completely harmless to both the user, the part, and the environment. A win for both the manufacturer and the planet. …Read More
Surface Preparation in Medical Device Manufacturing
In medical device manufacturing there exist critical surface preparation process requirements. This infographic compares the Surface Analyst™ to typical surface preparation methods used in the manufacturing of medical devices. Common methods include dyne ink and water break tests.
BTG Labs offers the Surface Analyst to accurately measure and monitor surface sensitive processes. Consequently, the Surface Analyst produces quantitative results on a highly precise level to assist in the required specification involved in the manufacturing of medical devices.
Utilization and Road Blocks of Dyne Inks
Manufacturers often employ dyne test inks, used for measuring wetting tension, to estimate surface energy (and therefore, surface cleanliness and treatment level). If you have ever used dyne, you know that applying these inks to your surface requires experience, training, and subjectivity. …Read More
