Stop Swapping Lamps and Start Looking at the Heat
Here is the thing about tempered glass: you can’t just buy a few new infrared lamps, look at the datasheet, and expect your bowing problems to vanish. It just doesn’t work like that. We see it all the time. A shop is struggling with stress points, so they swap out the bulbs. Then they’re left scratching their heads when the cold spots are still there. It’s not about the wattage. It’s about physics and where those lamps are actually sitting. The problem with heat Glass is stubborn. It doesn’t move heat around easily. If your heating array has gaps or the power is all over the place, you get these thermal gradients. When that glass hits the quench, those uneven spots turn into warps or—even worse—failed fragmentation tests. We don’t care as much about what the lamp is “rated” for. We care about how much energy is actually hitting the glass. Specs don’t fix a bad layout A high-wattage lamp sounds great on paper, but in the real world? It can burn your glass or leave “hot stripes” if the focal length is off. If you jump from a 2kW lamp to a 3kW lamp without moving the fixture, you’re probably just going to increase your scrap pile. You have to find that sweet spot between wavelength and intensity. We spend our time looking at your footprint. We check for those annoying dead zones or places where the heat overlaps too much. The hidden cost of “more power” Sure, pushing more power into a smaller area makes the cycle faster. But that comes with a price. High heat density puts a massive strain on your cooling systems. And your wiring? If it wasn’t built for that extra current, your terminals are going to fry way sooner than they should. That’s why we come on-site. A lamp is just a part; it’s not a strategy. The real answer is in the thermal map of the whole machine. We find where the heat is leaking and where it’s pooling. Once you see that, stopping the bowing becomes a lot easier.
