Advancements in Corning ColdForm™ Cold Bending Technology and Microcrystalline Glass Processing

Corning’s ColdForm™ technology is a patented innovation designed to bend glass without the need for heating, offering significant cost and energy savings compared to traditional hot bending methods.

Is Corning's Cold Bending Technology Applicable to All Types of Glass?

The answer is No. This technology is primarily suitable for tempered glass, particularly targeting Corning’s Gorilla Glass, known for its thinness, flexibility, and durability. However, cold bending may not be suitable for ordinary or more fragile types of glass.

For instance, microcrystalline glass, valued for its superior optical and mechanical properties, is widely used in 3C products such as smartphones, smartwatches, tablets, and other screen covers. Due to its high strength and toughness, microcrystalline glass requires hot bending temperatures of up to 900°C, making traditional 310S heating plates unsuitable for processing.

To address this challenge, Tianyi High-Tech has developed a superalloy composite metal heating plate with high resistance to oxidation, strength at high temperatures, and excellent thermal conductivity. This new heating plate is compatible with 3D glass bending machines, non-spherical glass precision press machines, and automotive curved glass bending machines, greatly improving both the production yield and forming accuracy of glass.
