        Kleiss Gears used sophisticated computer modeling to analyze how much force each individual gear exerts on its
        neighbor, then tweaking the shape of the next gear to optimize the interaction, overhauling Pleo's system.
        When Kleiss handed back the redesigned gears, some of them looked so weird – more like petaled daisies than
        sharp-toothed mechanical parts. But once installed, they ran in nearly perfect silence.

New Opportunities with Molded Gears, by R.E. Kleiss, A.L. Kapelevich and N.J. Kleiss Jr.

        Molded gearing includes plastic and powder metal injection molded gears as well as powder metal sintered gears.
        Near-net forged gears may also share some unique similarities and opportunities as well. This type of manufacturing
        offers some particularly intriguing opportunities for the gear designer, and also some challenges not usually
        encountered with cut gears.

        The challenges are often related to the mechanical properties of the material. Proper steel, cut and hardened
        correctly, is hard to beat for strength. Ordinary attempts to replace steel gears with the molded variety are usually
        doomed to failure.
