  • 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:

    • Die-casting
    • Machining
    • Washing
    • Assembly

  • Surface Analyst Inspection on Engine Casing

    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

    A Meeting of the Adhesion Society

    Annually, scientists, engineers, manufacturers, and students professionally concerned with the science and technology of adhesion, gather for a meeting of the Adhesion Society. Since 1978, this gathering has brought together these great minds to discuss, present, and learn the results of research and the newest findings in the science of adhesion.

    BTG Labs’ Chief Scientist Dr. Giles Dillingham has been presenting regularly since the late 1980s. In 2006, he was elected Fellow of the Adhesion Society in recognition of his contributions.

    This year he will be presenting at the 40th Annual Meeting happening February 26 – March 1 in St. Petersburg, Florida. Dr. Dillingham will present on a paper entitled, “Control of Cleaning Processes to Maximize Sealant Performance.”

    Controlling the cleaning processes of sealing surfaces in power train components is the key to long life and low warranty percentages in automotive manufacture. One of the final steps in the die-cast and machining process is cleaning. Current commercial washer systems can be quite effective at removal of particulate contaminates. The efficiency of washer systems has traditionally been evaluated using the Millipore Test. This method measures the mass of particulates post washing.
