The Quartz Thermal Insulation Plate Holder is a precision-machined fused quartz component specifically designed for supporting and p
ositioning quartz insulation plates in photovoltaic furnace tube openings. Manufactured from high-purity fused quartz, it provides excellent thermal stability, low thermal expansion, and superior resistance to thermal shock, making it an ideal solution for long-term operation in high-temperature environments.
The unique multi-slot structure securely holds multiple quartz insulation plates at uniform spacing, forming an effective thermal barrier around the furnace opening. This design helps reduce heat loss, improve temperature uniformity, and protect surrounding furnace components from excessive thermal exposure.
Our quartz insulation plate holders are widely used in photovoltaic diffusion furnaces, oxidation furnaces, semiconductor processing equipment, and other high-temperature thermal systems where precise insulation and reliable positioning are required.
