  • Process for manufacturing a leaf spring and insert for leaf spring
    Patent number: 12163565
    Abstract: An insert to a mold for a leaf spring comprises a substrate and a hole that extends through the substrate, A post protrudes from the substrate such that the insert, may be coupled to the mold. Further, the post covers the hole on a first end, so the hole is not exposed. On the other end of the hole, a thin overlay that covers the hole. Thus, during a process where resin is added to the mold, no resin enters the hole. The insert, when added to a leaf spring, offers reinforcement on areas where there is high stress. Therefore, holes may be added to a leaf spring at areas of high stress without overly weakening the leaf spring.
