In 2016, Ford Motor Company launched a challenge to Rassini International. The task is to reduce the weight of the rear suspension of the F-150 pickup truck. F-150 pickup truck is the flagship and landmark truck of the automobile manufacturer. Rassini is the largest supplier of leaf springs and other suspension components in North America. They have provided Ford with several solutions, but they prefer to combine traditional leaf springs with composite "auxiliary" solutions - this is a solution of multiple materials, representing an important growth opportunity in the automotive composite end market.
Achieve the goal of lightweight
Rassini, vice president of engineering and leaf spring and director of lightweight R&D, said that Rassini's position in the automotive supply chain makes it the preferred partner of original equipment manufacturers seeking innovative solutions. "When Ford Engineering considered how to develop the next generation of leaf spring suspension products, they would first come to us." Relevant personnel said, "They put forward some very aggressive lightweight goals for the chassis of the next generation F-150 truck, and they would like to know what we have in mind."
The plan given by Rassini to Ford complements the development trend of leaf spring in the history of automobile transportation. Early leaf spring design relied on the use of multiple steel plates with constant thickness, which were stacked and bundled together. As the payload increased, the steel plates were continuously joined from top to bottom. Over the years, with the improvement of steel quality, the number of steel plates in the package has gradually decreased, because they can bear the same load with fewer plates.
