TOQUARTZ® Solving Challenges with Fused Quartz Curved Plates

Fused Quartz Curved Plates for Infrared Heating Systems

Infrared heating system manufacturers require curved reflectors that can withstand extreme temperatures while maintaining optimal reflective properties. These systems are essential in industrial processes where precise, energy-efficient heating is required for materials processing, drying operations, and thermal treatments.

Key Advantages

TOQUARTZ® solution

Traditional metal reflectors in infrared heating systems often degrade after 2,000–3,000 hours, leading to frequent replacements and inconsistent heat output.

TOQUARTZ® fused quartz curved plates deliver over 10,000 hours of stable performance with >90% IR reflectivity, reducing maintenance frequency and improving energy efficiency by up to 20%.

Fused Quartz Curved Plates for Laboratory Equipment

Laboratory equipment manufacturers require optically transparent, chemically inert materials for reaction chambers, sample containers, and viewing windows. These applications demand materials that won’t contaminate samples, can withstand aggressive chemicals, and provide clear observation capabilities.

Key Advantages

TOQUARTZ® solution

An American laboratory equipment manufacturer struggled with local suppliers who couldn't meet ±0.2mm radius tolerance requirements, resulting in an 18% rejection rate.

TOQUARTZ® custom plates achieved consistent <2% rejection rates, dramatically improving their production efficiency and product reliability.

Fused Quartz Curved Plates for Industrial Furnaces

Industrial furnace manufacturers require viewing windows and radiation shields that can withstand extreme temperatures while maintaining structural integrity. These components are crucial for process monitoring and operator safety in high-temperature operations.

Key Advantages

TOQUARTZ® solution

Conventional glass shields in industrial furnaces often crack under thermal stress, risking equipment failure and safety hazards.

TOQUARTZ® fused quartz curved plates maintain structural integrity at 1100°C with minimal expansion, ensuring long-term reliability and precise fit in high-temperature furnace environments.
