About 30 to 40 pounds of adhesives are used in manufacturing today’s typical vehicle, cites PR Newswire. In an industry historically dominated by welding and mechanical fasteners, adhesive use is growing at a significant rate.
Let’s take a closer look at the growing importance of adhesives in automotive and the reasons why more original equipment manufacturers (OEMs) are turning to them:
Joining Dissimilar Materials
Welding, bolting or screwing dissimilar materials together used to be the norm. Yet as OEMs strive to meet the 2025 CAFE Standards, these traditional methods are no longer effective.
New combinations of lighter weight materials are being used, such as high-strength steel and aluminums. These materials help improve a vehicle’s fuel efficiency. However, these materials cannot be in contact with each other without corroding.
Adhesives in automotive offer the perfect solution. Serving as a separation barrier, adhesives enable the new, lighter weight, dissimilar materials to be joined together.
Offering Greater Production Flexibility
In addition to joining dissimilar materials, adhesives can be applied using automated dispensing equipment. Frost & Sullivan’s Market Insight states that this is an important factor driving adhesive use. The equipment can be easily adapted to various car designs. This lowers product waste, since the machine can be preprogrammed to dispense only the amount needed.
Additionally, the automated process helps accelerate the rate of production. Adhesives in automotive can be applied quickly and efficiently, saving OEMs time and money.
Improving Structural Integrity
Adhesives also help in improving a vehicle’s structural integrity. They spread stresses over a wider area than a weld or mechanical fastener. Adhesives also provide uniform strength throughout the entirety of a part.
