Haisung Aero-Robotics Co., Ltd., formerly known as Haesung TPC Co., Ltd., is a South Korea-based engineering and manufacturing company primarily engaged in the development, production, and distribution of precision reduction gears, geared traction machines, and mechanical drive systems for elevators, robotics, and aerospace applications. Founded in 1997 and headquartered in Incheon, South Korea, the company serves global industrial machinery, building transport, and automation markets. Its core product and service portfolio comprises geared traction machines and worm gear reducers for passenger and freight elevators; high-precision cycloidal reducers (cyclo drives) engineered for articulated industrial robots, collaborative robots, machine tools, and semiconductor automation equipment; specialized industrial gearboxes, slewing drives, and winch systems for wind power, maritime, and construction machinery; and customized high-torque actuators and precision power transmission components. Haisung Aero-Robotics distributes its solutions domestically and internationally, supplying tier-one elevator manufacturers, industrial robotics integrators, and heavy machinery equipment makers across Asia, North America, and Europe. In recent strategic developments, the company changed its corporate name from Haesung TPC Co., Ltd. to Haisung Aero-Robotics Co., Ltd. to reflect its expanded strategic focus on defense motion systems, aerospace robotics, and advanced air mobility drive mechanisms. Concurrently, the company has expanded production capacity for high-precision cycloid reducers to address rising demand in industrial automation, increased research and development investments in defense-grade robotic actuators and unmanned aerial drive units, and pursued strategic partnerships to integrate its precision mechanical systems into next-generation aerospace and smart factory platforms.
