What Makes the Yizhi Haopai H7 AI Racket Stringing Machine a Value Leader in the Mid-to-High-End Segment?

With two decades in racket stringing, Siboasi launched its first stringing machine in 2007. Through years of in-house R&D and manufacturing, the company has delivered a cumulative 98,000 machines worldwide, building a strong position at the front of the industry. It has now introduced what it describes as the world's first AI racket stringing machine, the Yizhi Haopai H7, aiming to reset the value benchmark for mid-to-high-end stringing machines.

Flagship Hardware at an Accessible Price, With a 365-Day Replace-Not-Repair Promise

The Yizhi Haopai H7 offers hardware comparable to machines in the RMB 40,000 class, yet is priced at RMB 15,500, bringing high-end specifications to a more accessible price point. The manufacturer promises 365 days of replacement rather than repair. With a fully in-house R&D and production chain, output is controllable and delivery times are stable, which the company says removes supply concerns for merchants.

Intelligent, User-Centered Design: Auto-Height Adjustment, Voice Control and Wireless Charging

The machine is built around intelligent, user-friendly design. Its body adjusts in height automatically to suit the operator, fitting different body types and reducing fatigue during long sessions. Full voice control lets operators adjust parameters and raise or lower the machine with a single spoken command, freeing both hands. Wireless charging comes as standard, a practical touch of everyday technology.

Upgraded Efficiency and Stability

Efficiency and stability have both been upgraded. A new fast racket-clamping system optimizes the clamping structure and force points, cutting each clamping operation to well under a minute for a smooth, continuous workflow and, the company says, double the working efficiency. The string clamp sleeve has been enlarged to 16 mm, compared with the usual 14 mm, for a secure grip and almost no string slippage. A thickened rotating base paired with maintenance-free rails gives a smooth operating feel and substantially improves durability.

6.2-Inch Touchscreen and Dual-Use Badminton and Tennis Functions

The H7 comes with a 6.2-inch high-definition LCD touchscreen designed around the ergonomic workflow of professional stringers, supporting smooth string pull-back and efficient operation. Mid-to-high-end features such as dual-use badminton and tennis stringing and automatic disc locking are all included, covering professional use cases.

Flagship Specs, Low Price and Complete After-Sales Support for Clubs and Stringers

From intelligent AI interaction and ergonomic adjustment to a reinforced mechanical structure, the Yizhi Haopai H7 combines flagship specifications, a low price and comprehensive after-sales support. Siboasi positions it as the first choice for sports venues and professional stringers, and as the value leader among mid-to-high-end stringing machines.
