Business Areas

• Globoid Worm Reducer and Gear Design/Manufacturing: We have self-developed a precision machining and mass production system for 'Globoid Worms' with maximized power transmission efficiency, to a world-first level. We supply core components to high-value-added industrial sectors where high-precision control is essential, such as robot joints, automation equipment, and the defense industry.
• Industrial Machinery Parts Manufacturing: Starting as an industrial machinery parts manufacturer in 1987, we possess parts manufacturing technology for various industrial fields such as valves, actuators, hydraulics, and automotive parts.

Products

• Globoid Worm: This is a next-generation worm gear product that minimizes noise and vibration while transmitting powerful force through an arc-shaped design with a wide contact area with the worm wheel. It possesses high torque transmission efficiency and excellent durability, contributing to reduced power loss and maximized equipment operating efficiency.
• WORM GEAR SETS: An optimized solution for applications requiring a 90-degree power transmission angle, the Double Enveloping (globoid) worm gear set is designed for companies that prefer to manufacture their own gearbox bodies. Customization is available according to customer specifications within the range of module 1-10 and gear ratios of 10/1 to 100/1.
• WORM GEAR BOX: It solves position accuracy-related problems that can occur in automation and servo-based applications, providing perfect positioning and position control without a feedback interface.

Special Notes

• Unique Technology and Patent Holdings: For over 35 years, we have accumulated unique technological expertise in the field of industrial machinery parts and reducer manufacturing. In particular, we succeeded in developing mass production facilities for 'globoid worms' using 10-axis control technology and have obtained invention patents both domestically and internationally.
• High Price Competitiveness and Customized Solutions: By utilizing our self-developed 10-axis control system, we maximize processing precision and have secured overwhelming price competitiveness compared to imported parts through technological localization. We also support customer-specific module design, solidifying a strong market position.
• Stable Business Operations and Growth Potential: Established on March 16, 2012, as a small and medium-sized enterprise, it demonstrates stable business operations by completing enrollment in the four major social insurance programs. Starting in 2025, it will enter full-scale mass production with patented, state-of-the-art facilities, preparing for its second leap forward.
