On the line, a single hot spot during preheating can turn a pane into a handful of unpredictable shards. Yield drops. Safety takes a hit. We built our infrared lamp for glass breaking to put down an even thermal field across the score line and the edges. The glass separates cleanly, instead of shattering under uncontrolled thermal stress. What matters under the hood We run short-wave infrared quartz emitters to put heat exactly where it’s needed—fast, with minimal convection. That gives you a repeatable, uniform thermal profile, and keeps the surface temperature in a tight band. Less localized expansion means fewer cracks. Power is matched to industrial duty cycles: quick ramp-up for high-throughput lines, stable dwell control so break behavior stays consistent. The lamp body is built for the plant—thermal shock resistant, and it mounts clean for retrofits. Why this plays in glass Even heating is the difference between a controlled break and a messy fracture. When the heat is uniform, the score propagates predictably, edges stay intact, and you don’t lose optical quality to warp or distortion from uneven expansion. Fewer rejects. Steadier cycle times. Less rework after cutting and before tempering. The fast response also keeps work-in-process lean, because the pane doesn’t sit around waiting for soak time. What you need to keep straight Match lamp power to glass thickness and emissivity. Too little power drags out the break; too much drives edge stress. Keep clearance to the glass and reflector alignment tight during changeovers, or hot spots will come back. We provide setup guidance for typical thickness ranges, but validate conveyor speed and dwell distance in trial runs before you roll it out across the line.
