Zhejiang Lishengtanhuang Co., Ltd.

Zhejiang Lishengtanhuang Co., Ltd. is a national high-tech enterprise focusing on the R&D of precision wave springs and spiral retaining rings and providing core solutions for global UAV power systems. At the UASE UAV exhibition, we focused on the following applications: drive motors: while providing precision preload, wave springs can reduce axial space by 50%, helping the lightweight design of electric drive components. Propellers and quick-release joints: self-locking spiral retaining rings possess excellent dynamic balance performance, effectively resisting high-speed centrifugal force and ensuring firm connections. Extreme environments: using high-performance materials such as 17-7PH and Inconel and having passed IATF16949 certification. Lisheng advantages: providing mold-free customization services and quickly responding to UAV R&D needs, helping aircraft fly higher and farther.
