High-Alumina &
Panda Glass
Industrial-grade aluminosilicate cover glass engineered for demanding display and touch applications. From blueprint to mass production -- with the transparency and certainty your supply chain demands.
What Is High-Alumina / Panda Glass -- and Why It Matters
High-alumina glass (often referred to by trade names such as "Panda Glass") is an aluminosilicate substrate that undergoes a controlled ion-exchange chemical tempering process. This replaces smaller sodium ions at the glass surface with larger potassium ions, generating a deep compressive stress layer that dramatically increases scratch resistance, drop performance, and flexural strength compared to standard soda-lime glass.
At Winson Optics, we source verified aluminosilicate substrates and process them through our Shenzhen cleanroom facility -- cutting, edging, drilling, silk-screen printing, AR/AF coating, and final 100% AOI inspection -- delivering a finished, ready-to-assemble cover glass panel precisely to your drawing.
Whether you need a small R&D prototype batch or a high-volume production run for a consumer or industrial product, our procurement-minded workflow eliminates the hidden costs and quality surprises that haunt international buyers.
The Winson Difference: Procurement Thinking in Manufacturing
Our partner Iris brings 12 years of professional procurement experience to the factory floor. We anticipate your QA requirements, documentation needs, and delivery expectations before you ask.
