When a material begins its journey through a manufacturing process it becomes crucial to know and control everything that happens to that material as it makes its way down the line. There are two major factors to consider when understanding and controlling what happens to the surface of that material: the actual physical space of the warehouse and the time it takes to get through the entire process of being bonded, coated, painted, sealed, glued or printed. If you don’t know precisely what is occurring at each Critical Control Point and you don’t continually monitor the surface throughout the duration of the process, you could be trending towards adhesion failure and not even know it.
Ever wonder what a hungry BTG Process Engineer is pondering while preparing the turkey for the feast of gratitude to be shared around the Thanksgiving table? The sharp minds at BTG Labs are ever vigilant in the quest for a surface state properly prepared for the task at hand; whether that be parylene conformal coating, interfacial bonding of composites, catheter coating, or turkey roasting. For the application (turkey) to be a success (taste good) there are Critical Control Points that must be closely monitored throughout the process (roasting up the bird).
What is a Critical Control Point?
A Critical Control Point (CCP) is any point in the manufacturing process where the surface condition of a material has the opportunity to change—intentionally or unintentionally—and impact adhesion, in a positive or negative way.
Why should you care about them?
The wait is finally over. Making its world debut at MD&M in Minneapolis, the Surface Analyst XA integrates the power, simplicity and ease of our handheld Surface Analyst directly into the manufacturing process. Now, the most precise surface monitoring technology will seamlessly unify with any production line, magnifying the speed and efficiency of surface quality control.
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…
New industry buzzword?
Or a new generation of process and quality control?
Parts washers play an integral role in manufacturing, especially on machined parts and bonding surfaces. Prior to coating, sealing, painting, and welding, parts washers help remove contaminants generated from fabrication to facilitate stronger bonds.
But, for a reliable bond to form, the surface must not only be free of particles, it must also be chemically clean. Thus, quantifying and analyzing parts washer effectiveness in removing chemicals is the key to ensuring the desired surface is achieved.
The importance of monitoring cleaning processes in preparation for bonding is becoming increasingly necessary as sealing processes are rapidly replacing traditional mechanical fasteners and gaskets.
However, when sealing, the surface must be clean and clear of contaminants to guarantee the bond. The Surface Analyst monitors and optimizes washer systems to ensure the part comes out chemically clean and ready to hold a reliable bond. …Read More
