Getting the Heat Right for Rocket Fairing Paint
When you’re curing paint on a rocket fairing, you’re dealing with a massive surface. The biggest nightmare? Cold spots. If your lamp layout has gaps, the heat doesn’t hit evenly. That’s how you end up with paint peeling off or a weird, patchy gloss that looks amateur. We fix this by building modular infrared arrays that basically kill off those thermal dead zones. The secret is in the overlap. Most people just line lamps up end-to-end, but that doesn’t work. Quartz tubes lose their punch at the edges. To stop that, we calculate a specific overlap for every lamp. By layering those heating zones, the surface temperature stays rock-solid across the entire fairing. No dips, no surprises. Then there’s the power. Running a high-wattage array over a huge area is a lot of electrical stress. Instead of one giant circuit, we use zoned controls. This lets you split the array into different banks. If the center of the fairing needs a different touch than the edges, you just tune them separately. And because things get incredibly hot, we don’t mess around with the wiring. We use heavy-duty connectors and high-temp lead wires so nothing melts or shorts out while you’re in the middle of a run. Dealing with the intensity. Shortwave IR lamps hit the paint fast. That’s great for keeping the line moving, but it’s tough on the hardware. We add reflective aluminum backing to the housing, which bounces the wasted heat back onto the work instead of letting it vanish into the room. But you have to be careful with the wattage. Push too hard in a tight spot and you’ll scorch the paint. Plus, your cooling system has to be up to the task. If it can’t handle the ambient heat building up around the frame, your electronics are going to trip. Keeping things simple. We build these as drop-in modules. Why? Because tubes eventually blow. When one goes, you don’t want to tear down the whole rig and lose a day of production. You just swap the module and get back to work. It’s that simple.
