Out on the line, heat isn’t a nice-to-have. It’s the knob the whole process rides on. When the heating profile wanders, you feel it fast—coating blisters, lamination voids, insulating glass seal failures, and tempering stress fractures. Chasing temperature uniformity eats hours and turns good glass into scrap. We built an affordable infrared radiator to cut that guesswork out. What actually matters under the hood This unit leans on near-infrared (NIR) quartz emitters to put energy straight onto the surface. The response is measured in seconds, not minutes, so setpoint changes keep pace with what’s happening in real time. It runs on 230 V or 400 V, in standard lengths that drop into existing oven zones, and the footprint is tight enough to retrofit without tearing the line apart. Peak wavelength and controlled emissivity give you a clean thermal front—heat the glass surface while you limit parasitic convection losses. Power density is matched to glass work: enough to hit bend and temper temperatures quickly, but controlled enough to avoid hot spots. Modular mounting and a solid terminal layout make installation repeatable and swap-outs simple. Why it sticks in real glass work In tempering, the quicker the glass hits quench temperature, the higher your throughput—and the lower the risk of optical distortion. In EVA and SGP lamination, a stable, uniform thermal field collapses entrapments and keeps optical clarity on spec. For insulating glass, fast, even heating on the primary seal tightens variability and shortens cycle time. On automotive and architectural lines, the same module fits into coating drying, bending, and preheat stations. Energy use drops because NIR heats the product directly, not the air around it. We’ve got units running 5,000+ hours with less than 5% output drift, and the replaceable element design keeps maintenance straightforward. Here is what you need to get right NIR heating is line-of-sight, so set the zone geometry so every pane sees the intended flux profile, and keep reflectors aligned to the glass path. The emitter surface runs hot—guarding and interlocks are a must for operator safety. Clearances matter, because radiant heat reflects and reradiates. Match the spectral output to the coating or interlayer, and calibrate the controller to the glass emissivity at operating temperature. If your oven pushes a lot of airflow, shield the emitters so temperatures stay stable.
