One Company, Two Core Engines.
Text after title text example
Shenzhen Xinhongsen Optical Technology Co., Ltd. (also known as Hongyuan Optics) is a premier manufacturer established in 2009. We specialize in the research, development, and production of high-quality sapphire crystal watch glass and optical components.
But we are more than just glass makers. To achieve the ultimate precision (HV1800 hardness, ±0.01mm tolerance), we engineered our own solution: Huayuan Hongda Machinery (HYHD).
This strategic duality allows us to control the entire value chain. We use our own machines to produce your glass, and we use our glass production experience to refine our machines. This is our "Front Shop, Back Factory" advantage.

Our Philosophy
"Technology serves life, integrity drives value, and innovation guides future development."
The Integrated Advantage
"We don't just cut glass; we build the machines that perfect it."
Founded in 2009, Shenzhen Xinhongsen Optical Technology Co., Ltd. began with a simple mission: to produce the world's finest sapphire watch crystals. However, we quickly realized that standard market equipment couldn't meet our exacting standards for hardness (HV1800) and precision.
This drove us to establish Huayuan Hongda Machinery (HYHD). By developing our own CNC grinding and polishing lines, we achieved a closed-loop ecosystem. Today, XHS focuses on optical products for luxury brands, while HYHD exports state-of-the-art machinery to manufacturers worldwide.
