Kowy Achieves Milestone Breakthrough in Technology: Successful Development of Core Components for Large Model RT-828

Ninghai, China, Dec 2025 – Ninghai Sanyuan Electric Tools Co., Ltd. (Kowy Brand) officially announced today a major breakthrough in its technological efforts for large steel bar tying equipment. The core components for the new flagship model RT-828, designed for heavy infrastructure projects, have completed R&D and internal testing. This marks a crucial leap for the company in achieving independent and controllable technology for automated tying of super-large diameter steel bars.

The RT-828 project aims to tackle the challenge of automated tying for giant steel bar bundles with diameters exceeding 45mm and even reaching 80mm, meeting the stringent demands of national key projects such as mega-bridges, nuclear power facilities, and deep-water ports. The breakthrough centers on two independently developed key systems:

1.Ultra-High-Pressure Intelligent Tying System: This system successfully resolves the issue of locking force and consistency for tying wire under extreme load. Through an innovative hybrid hydraulic and electronic control design, it achieves a tying force over 300% greater than conventional models while ensuring each action's precision and reliability, guaranteeing absolute stability for giant steel bar structures.

2.Heavy-Duty Adaptive Drive Module: Addressing heavy wire reels and immense resistance, this module delivers unprecedented drive torque and motion stability. Its built-in intelligent sensing system provides real-time feedback on load changes and dynamically adjusts output, ensuring the equipment's endurance and smooth operation during continuous high-intensity work.

"Finalizing the core components of the RT-860 is not just progress on a product; it represents the determination and capability of the Kowy technical team to challenge the industry's technological boundaries," said Mr. Hua, the company's Product Director. "This clears the most significant technical obstacle for our subsequent steps of complete machine integration, testing, and eventual market launch. We will expedite prototype manufacturing to provide this 'power-grade' solution to global heavy infrastructure customers as soon as possible."

This breakthrough in core technology will not only consolidate Kowy's leading position in the high-end steel bar tying equipment sector but also lay a solid technical foundation for the company's entry into the special engineering machinery market. Kowy remains committed to driving innovation and strives to be a trusted technological partner in the global construction automation field.
