Dealing with Tight Spaces in Weirdly Shaped Furnaces
Let’s be honest: standard straight-tube infrared lamps are great until they aren’t. The moment you’re working with a non-standard bending furnace or a cramped batch chamber, those “off-the-shelf” parts just don’t cut it. You try to jam them in, and suddenly you’ve got cold spots all over your workpiece or heat that’s just not hitting where it needs to. We fix this by actually shaping the heating elements to fit your specific furnace. No forcing it. No “making it work.” Just a custom fit. Making the heat wrap around your part When space is tight, a standard lamp is a liability. One wrong move and it’s touching the furnace wall or, worse, the part you’re trying to heat. That’s why we bend the quartz tubes to follow the actual curve of your chamber. Instead of firing heat from a distance, you can essentially wrap the heat source around the part. It gets you a much higher heat density because the element can sit closer to the target without causing a short or a mechanical meltdown. The tricky part about bending Here is the thing: bending a tube isn’t just about the fit. It changes how the heat behaves. When you curve a tube, the infrared flux concentrates right at the bend. If you aren’t careful with the wattage per centimeter, you’ll burn out the filament in no time. We spend the time balancing the voltage and wattage so the quartz doesn’t overheat, but you still hit your temperature setpoints exactly where you need them. Getting it installed without the headache Nobody wants to rewire an entire control panel just to swap a lamp. We handle the terminations for you—whether that means specific lead lengths or industrial connectors—so the custom lamps just drop right into your existing wiring harness. But a quick word of warning: quartz expands when it gets hot. Custom-shaped lamps behave a bit differently than straight ones. **Give the lamp some room to breathe.**If you pin the tube too tightly against a rigid frame, it’s going to snap the first time you power it up. Leave a little wiggle room in those mounting brackets, and you’ll be golden.
