Out on the line, yield lives or dies at the edge. One hairline thermal fracture near the perimeter can kill a tempered pane that passed every earlier check. Standard convection heats the whole sheet, not just the edge, and that extra thermal load is what drives stress and optical distortion. We built our glass edge heating lamps to put heat right where it matters—at the edge—so the rest of the glass stays in the right thermal window. We use short-wave infrared (SWIR) quartz emitters, tuned for fast response and tight control. The peak wavelength is matched to how glass absorbs at the edge, so the energy goes into the material instead of warming up the air. That gives you a quick, localized thermal zone with minimal convection and a predictable temperature gradient. You get repeatable heating profiles for edge work in tempering, bending, lamination preheat, and coating drying—without overheating the field. On the floor, that means fewer rejects from edge micro-cracks, less scrap from thermal shock, and cycle times that don’t jump around. The lamp comes up to temperature fast, so you can keep pace with high-throughput lines without waiting on warm-up. You also save energy because you’re not heating the entire furnace or chamber. The module is designed for drop-in fitment, so it integrates into existing equipment with minimal rework. Installation comes down to the workpiece path. Alignment to the edge is critical—even a small offset shifts the thermal profile and can cause uneven heating. The lamp performs best when the glass edge position is stable and repeatable. You’ll want to dial in power and dwell time for your specific glass thickness and edge geometry, but once you set it, the process stays steady.
