Stop Fighting Your Furnace Space
Let’s be honest: standard infrared lamps are great until they aren’t. If you’re working with a cramped furnace or some weirdly shaped glass, those off-the-shelf tubes just don’t cut it. You end up with “dead zones” where the heat doesn’t hit, and that’s where the mistakes happen. We fix this by ditching the generic stuff. We build lamps in the exact lengths and shapes your specific chamber needs.
Getting the Shape Right
Straight tubes and curved glass don’t mix. It’s a recipe for uneven heat. Instead, we bend our lamps to follow the actual curve of your workpiece. This keeps the heat steady across the whole surface. But we don’t just bend the glass and call it a day. When we change the length, we tweak the wattage and voltage too. Why? Because if the power density is off, your filament is going to burn out fast. Nobody wants to deal with that downtime.
The Nitty-Gritty on Materials
We use high-purity quartz because it can take the beating of rapid heating and cooling without cracking. For most glass bending, short-wave infrared is the way to go—it just gets into the material faster. Depending on your setup, you can go with clear quartz for raw power, or coated tubes if you need to keep the heat from baking your furnace walls. One quick heads-up on the wiring: we can do standard or custom connectors to fit your rails, but keep an eye on your temps. If you cram more wattage into a tight space, your control electronics are going to feel it. Make sure your cooling fans are up to the task.
Making it Fit
The best part? Custom shapes let you pack more heating power into the same small area. You don’t have to rip out your furnace shell or rebuild the entire frame. These are designed to be drop-in replacements that fit your existing brackets. Just send over your CAD drawings, and we’ll make sure they slide right in the first time. No guesswork, no “almost fits,” just a setup that actually works.
