Competition is hot in the fast-paced automotive industry, and manufacturers work intensively to create more efficient, reliable vehicles. When the race is head-to-head, there is no room for failure. Finding ways to avoid failures and produce a more reliable vehicle provides a competitive edge.
New technologies such as FIPG (formed-in-place gaskets), which contribute to a more efficient, reliable system, can provide that needed edge. As a replacement for traditional gaskets such as cork and rubber, FIPG sealant is stronger and more reliable. An adhesive applied directly on the factory floor, FIPG increases efficiency and reduces waste. The adhesive also makes a stronger seal than traditional gaskets and can tolerate more wear, so failure rates decline significantly. However, with this new technology comes new specifications and assembly processes.
The integrity of FIPG relies on the surface cleanliness of the part before sealing. The part’s surface must be clean and clear of chemical contaminants to maintain a strong seal and avoid failures. In the past, cleanliness in the automotive industry only presented a concern with moving mechanics, so grit and dirt were the primary threats. But, when applying FIPG, contaminants can be more than grit and dirt; various assembly liquids—mold releases, detergents, cutting fluids—exist in the manufacturing processes and can derail this imperative bond.
Several cleaning processes, such as parts washers and solvent wipes, are used to clean surfaces in the automotive industry; however, without a way to monitor and verify these cleaning processes, the level of surface cleanliness remains unknown.
This case study details the journey of an engine block manufacturer who transformed their cleaning process from a chance-based system to a data-driven approach. The manufacturer, a supplier to one of the "Big Three" US automakers, relied on field failures to assess the effectiveness of their industrial parts washer. This reactive approach lacked control and risked costly product failures.
Brighton Science's surface science expertise, plus innovative technology, provided the missing piece. This solution allowed the manufacturer to:
By replacing guesswork with data-driven cleaning processes, the engine block manufacturer achieved:
By focusing quality efforts on controlling surface cleanliness and transitioning to a data-driven approach, this automotive manufacturer achieved reliable FIPG bonding, minimized waste, and delivered a consistently high-quality product to their customers.
