Hontech Glass-Ceramics Successfully Develops 8mm Glass-Ceramic Thick Plate, Leading Innovation in Induction Cooktop Panel Industry

Recently, Dongguan Hontech Glass-Ceramics announced a groundbreaking achievement: after years of dedicated research and technological breakthroughs, the factory successfully developed an 8mm glass-ceramic thick plate by the end of October 2008. This milestone not only fills a domestic gap in glass-ceramic thick plate production but also revolutionizes panel material solutions for high-power induction cooktops.

According to Hontech Glass Products’ technical director, the 8mm glass-ceramic plate is specifically engineered for high-power induction cooktops. Utilizing a unique controlled crystallization process, precise temperature and timing protocols enable the formation of uniform microcrystalline structures within the glass. This results in a material combining glass-like transparency with ceramic-grade strength.

Key Performance Highlights

1. Exceptional Durability
   • Impact resistance is 5–8 times higher than conventional glass.
   • Withstands 200kg loads under continuous 24-hour high-temperature operation without deformation or fracture.
   • Performance metrics exceed international standards, making it ideal for demanding environments like commercial kitchens.
2. Thermal Stability Innovation
   • Optimized material composition and heat treatment minimize the coefficient of thermal expansion (CTE).
   • Maintains structural integrity even under rapid thermal cycling (e.g., repeated exposure to extreme cold-to-heat transitions).
   • Resolves traditional panels’ issues of cracking and warping under prolonged high-power use.

Industry Impact and Recognition

• Rigorous Validation: Passed testing by multiple leading induction cooktop manufacturers.
• Patented Technology: Secured multiple national patents for material formulation and processing.
• Expert Endorsement: Industry analysts highlight its role in advancing China’s glass-ceramic manufacturing capabilities and enabling lighter, more efficient designs for high-power appliances.

Future Development

Hontech Glass plans to expand R&D investment to develop diverse glass-ceramic specifications tailored to broader applications, driving China’s specialty glass materials industry toward global technological leadership.
