Stop Guessing with Your Glass Cutting Heat

Anyone can sell you a replacement heating lamp. That’s the easy part. The hard part? Actually getting the thermal profile right so your safety glass cuts cleanly every single time. We’ve seen too many lines struggle because they relied on a datasheet. A wattage rating is just a number—it doesn’t know how fast your conveyor is moving or if there’s a drafty door letting cold air hit your glass. That’s why we don’t just put tubes in a box and ship them. We get on your floor and actually look at what’s happening.

Getting Low-E Glass Preheating Right When You’re Going Wide

If you’re trying to preheat Low-E glass that’s wider than 3 meters, you’ve probably realized that standard infrared lamps just don’t cut it. You end up with those annoying cold spots across the glass, and in this business, that’s a problem. We build continuous infrared heating units specifically to fix that. The goal is simple: make sure the heat is dead flat from one edge to the other. No surprises.

Thermal stress glass cutting

On the line, a clean score is the one that parts cleanly—no hairline cracks. If you don’t manage thermal stress, the cut edge walks micro-cracks right into tempering, bending, or lamination, and those defects compound downstream. We set up the heating module to nail the surface temperature fast, so scoring is about predictable stress, not guesswork.

What matters, technically

The heart is a short-wave infrared emitter with a spectral response tuned to couple hard into glass—surface heat, fast, without driving the bulk. Keep the band tight—±2% across the active length—and the thermal front stays uniform, so expansion lines up along the score. It runs on 240 V or 480 V, drops into standard ceramic holders, and the quartz envelope takes repeated thermal shock without drama. The response is quick: full power in under 2 seconds, and the control takes 4–20 mA from your PLC so timing lands exactly where you want it. We’ve run units 5,000+ hours with less than 5% output drop, so stability holds shift after shift.
