Thanks to advancements in powertrain manufacturing, sealing processes have improved assembly efficiency. Formed-in-place gaskets (FIPG) are replacing traditional mechanical fasteners as they are more cost effective, stronger, and easier to apply. However, adhesive bonding rather than mechanically fastening presents different challenges and requires new protocols.
Lead Sales Engineer Lucas Dillingham has presented “Defining Cleanliness in Powertrain Manufacturing for FIPG Applications,” at several events and automotive factories. BTG Labs works with numerous automotive manufacturers on surface chemical cleanliness and what it means for assembly.
Traditional millipore tests reveal particulate contamination, but on a sealing surface, one must detect chemical contamination. To adhere successfully, surface cleanliness on a chemical level is vital.
A byproduct of automotive manufacturing processes is contaminants that are detrimental to adhesion. Processes entailing unwanted contaminants include:

Manufacturers working with metal are all too familiar with the obstacles that come along with coating, painting, bonding, printing, or sealing it. While the uses of metal in manufacturing are countless and exist in numerous industries, the common denominator is ensuring the appropriate surface cleanliness prior to surface critical processes to guarantee successful adhesion. Common surface cleanliness gauges—dyne inks and water break—are subjective and do not offer quantitative results. Water break can be messy and time consuming and dyne is destructive to the part and dangerous to the user. While these methods can offer some insight into surface cleanliness, they are less than ideal.
BTG Labs Surface Analyst is a fast, easy, accurate, and non-destructive surface cleanliness gauge that tells the user right on the manufacturing floor how prepared the surface is to bond. This hand-held instrument improves surface processes and guarantees a bond will stick. Numerous manufacturers in industries such as consumer goods, automotive, and aerospace, have implemented the Surface Analyst in their specifications to improve their critical metal surface processes. …Read More

It’s the first day of spring. Depending on where you live, this could mean opening the windows, planting seeds, rolling out the motorcycle, and waiting for Opening Day. Here at BTG Labs, we think of spring cleaning. Of course, this usually generates visions of humming vacuums and sloppy mops, but, we see whooshing parts washers and smooth solvent wipes. Why? Well, because our instrument, the Surface Analyst is a significant player in the cleaning game.
The Surface Analyst is the keystone to verifying, troubleshooting, monitoring, and even choosing a cleaning process.
A cleaning method is only as useful as it’s verification process. In under two seconds, the Surface Analyst measures water contact angle to determine surface cleanliness. The instrument can be programmed to produce a pass/fail result based on the manufacturer’s specifications. This is an easy, objective method that immediately assures the technician of the surface cleaning process.
Furthermore the Surface Analyst can be used to choose the most efficient cleaning method and optimize existing cleaning methods. Sometimes a particular solvent is more effective than another or the water in a parts washer becomes dirty. The Surface Analyst helps detect these elements to ensure the process is running flawlessly.
Lastly, the Surface Analyst helps manufacturers choose the best cleaning method for their manufacturing process. In most scenarios, the only way to test a cleaning process is in the field or the laboratory. This is time consuming and causes failures and waste. The Surface Analyst, on the other hand, tells the user right on the factory floor, whether or not the part has been properly cleaned to bond, print, seal, coat, or paint without out wasting time or material. …Read More
