Redefine "Made in China" on the green.

1.From scale to precisio

China's manufacturing advantage begins with scale. Yihong, in its early stages, established a full industrial chain base covering everything from core layer research and development to shell molding. This industrial scale efficiency not only means leading output but also signifies that we have the most complete accumulation of underlying data.

1.2 Turning Point: The Awakening Driven by Precision
When global table tennis enthusiasts place stringent demands on feel, spin, and flight stability, traditional low-cost manufacturing has become a thing of the past. Yihong realized that true competitiveness lies in micrometer-level precision control. We shifted the narrative focus from 'how much we can produce' to 'how accurately we can produce'.

2.Advanced Materials Science — The 'Core' Secret of Golf Balls

The performance of a golf ball is, essentially, a precise game of material mechanics. In Yihong's R&D laboratory, each ball undergoes a revolution of chemistry and physics.

2.1 Exclusive Rubber Formula: The Power Source (The High-Energy Core)

We use high-elasticity polybutadiene rubber combined with Yihong's unique cross-linking catalytic technology.

Energy Conversion Rate: By precisely controlling the vulcanization temperature and time, our core can achieve an extremely high coefficient of restitution (COR), ensuring minimal energy loss during powerful hits.

Performance Consistency: Formula deviations are controlled within 0.1% for each batch, ensuring that balls taken from different bags fly on identical trajectories.

2.2The Art of Polyurethane (Urethane): Control at the Edge of the Green
The soul of high-end tournament-grade balls lies in the cover. Yihong has mastered the cutting-edge **cast urethane** molding process.
• Ultra-thin cover technology: We have successfully compressed the cover thickness to the limit while maintaining extremely high cut resistance.
• Grip optimization: This material provides the perfect "bite" for club grooves, delivering amazing stopping performance on short-game attacks to the green.

3.Exquisite Craftsmanship — A Commitment to Every Micron

3.1 Aerodynamics: The 338 dimples on the philosophical golf ball surface are not decorations, but complex fluid mechanics. Wind tunnel simulation: Yihong's engineers use computational fluid dynamics (CFD) to simulate tens of thousands of dimple arrangement combinations. Symmetry and balance: We use fully automated precision mold processing to ensure that the depth and edge sharpness error of each dimple is less than $0.005mm$, completely eliminating asymmetric sidespin during flight. 3.2 Automated Precision (Smart Manufacturing) In Yihong's factory, Industry 4.0 has already been implemented: X-ray eccentric detection: Each ball is scanned with ultrasound or X-ray before leaving the factory to ensure the core is 100% centered. Multi-layer composite pressing: Whether it is a three-layer or four-layer ball, we use vertical pressure sensors to monitor and ensure the adhesion force between layers reaches the peak industrial level.

4.Seamless Global Supply Chain – Ultimate Efficiency from the Production Line to the Green

4.1 Advantages of Vertical Integration

Yihong deeply cultivates the core areas of Chinese manufacturing and possesses unparalleled supporting services.

Direct supply of raw materials: Establishing deep strategic cooperation with top global chemical suppliers to ensure the stability of raw materials.

Flexible production: Whether it is high-end OEM/ODM for globally renowned brands or small-batch customization for startup brands, Yihong can complete the transition from R&D to mass production in the shortest possible time.

4.2 "China Speed" in Global Logistics

Relying on China's mature cross-border logistics system, Yihong achieves seamless connection from workshops to major global ports.

Timeliness guarantee: Our digital warehouse management system ensures inventory turnover rates leading the industry.

Technical support: We offer not just products, but a full set of supply chain solutions including technical documentation, compliance testing, and intellectual property protection.

5.ESG and Sustainable Development — The Commitment to Green Manufacturing

As an industry leader, Yihong deeply understands that precision manufacturing must be rooted in sustainability.

Waste Recycling: We have established a comprehensive waste reuse system to reduce our environmental footprint.

6.Clean Energy: The factory is gradually introducing solar power systems to promote low-carbon production.

.Yihong — Redefining Precision for You Every time a golf ball takes off, it is a collision of technology and nature. From Made in China to Exquisitely Made in China, Yihong Golf has journeyed from following to leading. We firmly believe that ultimate precision speaks for itself. When you swing and hit the ball, the crisp sound and perfect flight arc are Yihong's calling card presented to the world.
