Getting the Heat Exactly Where You Need It: Custom SWIR Tubes

Let’s be honest: standard straight heating lamps are great until they aren’t. The second you’re dealing with a non-standard bending furnace or a cramped oven layout, those stock lamps just don’t cut it. They don’t fit, and they definitely don’t hit the right spots on your workpiece. That’s why we build short-wave infrared (SWIR) tubes that actually fit your space—custom lengths, custom bends, the whole deal. Making the shape work for you We bend quartz glass to match the inside of your furnace. But this isn’t just about squeezing a lamp into a tight corner. It’s about distance. Short-wave radiation moves in a straight line and doesn’t get bogged down by the air. By curving the tube, we can essentially wrap the heat around your part. You get a much more even soak across complex surfaces instead of having “cold spots” that ruin a batch. The nitty-gritty (and the trade-offs) You tell us your power grid—220V, 380V, whatever you’re running—and we tweak the tungsten filament density to get the heat flux you’re looking for. But here’s the thing: when you pack a lot of wattage into a short, bent tube, things get hot. Really hot. You’ve got to make sure your furnace housing is vented properly. If the air around that quartz tube gets too trapped, you’re looking at deformed glass or a burnt-out filament. To keep things from spiraling, we usually suggest pairing these tubes with PID controllers. It keeps the temperature steady and stops the system from overshooting. Getting it up and running We offer a few different end-cap options so you aren’t fighting with the wiring. The best part? Because these are shaped to your specific gear, they usually just drop right in. You don’t have to rip out your entire furnace chassis or redesign your whole line. You just get the heat exactly where it needs to be, without wasting energy heating up the furnace walls.

Getting Silk-Screening and Tempering Right (Without Burning Your Ink)

Here’s the struggle when you’re trying to silk-screen and temper glass in one go: you’re fighting a war between the ink and the glass. You need enough heat to get that glass strong and stress-free, but if you push it too hard, you’ll toast your artwork. It’s a tight window. To hit that sweet spot, we use short wave quartz infrared lamps. Why short wave? Think of it this way. Medium wave heat kind of hangs around the surface. But short wave? It cuts right through. It hits the glass substrate fast and hard, driving the temperature up to the tempering point before the ink on the surface has a chance to burn. The result is a pane that’s rock solid, but the image stays crisp. No blurring, no scorching. Just a clean look. Picking your gear We use high-purity quartz tubes because they can handle the thermal shock without cracking. But you can’t just plug any lamp in and hope for the best. You have to match your wattage and voltage to how fast your conveyor is moving. If you’re running thick glass, you need that high-wattage punch. Just be careful. If you crank the power but keep the belt moving slowly, you’re going to fry your ink. It’s all about that balance between heat density and speed. The nitty-gritty of installation We keep the connectors standard. Why? Because nobody wants their entire line dead for half a day just because one tube popped. You want to be able to swap them out and get moving again in minutes. One thing to watch out for: these lamps put out an incredible amount of heat in a very small space. If your ventilation is lazy, the oven housing is going to soak up all that heat. Eventually, that kills the lamps and can even warp your brackets. And for heaven’s sake, use high-temp leads. You don’t want to find out the hard way that your insulation has melted into a puddle.
