When it comes to tempering ultra-thin photovoltaic (PV) glass, the choice of the tempering furnace is crucial. The process requires advanced technology and precise control to ensure high-quality output. Among the available options, the Continuous Glass Tempering Furnaces from LandGlass stand out as the best choice for this task.

Main Challenges in Ultra-Thin Glass Tempering

1. Surface Stress Issues

Ultra-thin glass loses heat quickly after heating stops, making it difficult to achieve the necessary temperature gradients for proper tempering. This is particularly challenging for 2mm dual-pane PV glass.

2. Surface Quality Concerns

Thin glass tends to get deformed when making a stop in or passing through the furnace. Uneven heating and cooling can result in warping, surface waves, and stress marks, compromising the glass's optical properties and surface quality. 

To overcome these challenges, advanced technologies in glass transmission, heating, cooling, and control are essential. LandGlass Continuous Glass Tempering Furnaces offer precise temperature control, optimized cooling systems, and high productivity. They are specifically designed to meet the stringent requirements of tempering ultra-thin dual-pane PV glass, ensuring high-quality, defect-free results.
