Getting Heat-Shrink Right on Aircraft Cable Harnesses

When you’re shrinking sleeves on aircraft wire bundles, there’s no such thing as “close enough.” If you push the heat too far, you end up with brittle polymers or, worse, charred cores. It’s a nightmare. That’s why we use shortwave infrared (IR). Instead of just blasting everything with heat, IR targets the shrink material itself. This means the inner copper conductors stay cool while the sleeve does its job. Why air ovens just don’t cut it Most people start with standard convection ovens. The problem? They heat the air. It’s slow, it’s clunky, and it’s imprecise. Our IR lamps work differently. They send out radiation that goes straight into the shrink sleeve. We’ve tuned the wavelength so the energy hits that outer polymer layer and stops there. No more worrying about burning out your primary insulation. You get a tight, clean seal in a few seconds. It’s a massive time-saver. The nuts and bolts We build these lamps with high-purity quartz tubes because they can handle the stress of heating up and cooling down over and over again. We also spec the reflectors to focus the beam exactly where the cable is, so you aren’t wasting energy heating up the room. Depending on how fast your line moves, you can pick different wattage options. If you’re dealing with thick-walled sleeves, you’ll want the high-wattage tubes for that quick ramp-up. Just a heads-up: make sure your power supply can handle the initial inrush current, or you’ll be tripping breakers all morning. Making it work in your shop Getting these into your production line is easy. We use standard connectors, so if a tube wears out, you just pop it out and drop a new one in. But here’s the thing: high-density IR arrays put out a lot of heat. If your housing isn’t vented right or your fans are too small, the ambient temperature will start to climb. That can throw your whole process off. My best advice? Keep your sensors pointed at the surface of the sleeve, not the lamp. That’s the only way to make sure your shrink rate stays consistent every single time.

Why IR Curing Actually Matters for Aircraft Coatings

We use short-wave infrared (IR) lamps to dry our aerospace coatings. Now, on the surface, it looks like we’re just trying to move planes through the hangar faster. But it’s deeper than that. The way IR heat hits the paint actually changes how the plane handles a bird strike or a spray of gravel at 500 mph.

Getting the chemistry right

Think about a standard convection oven. It heats the air, then the surface, and then the heat slowly creeps inward. It’s a slog. IR lamps are different. They send electromagnetic radiation straight through the coating. It hits the bottom and the top at the same time, triggering the curing process everywhere at once. When the coating cures evenly from the metal skin all the way to the surface, it doesn’t get as brittle. That’s the key. A brittle finish just snaps under the pressure of an impact. But an IR-cured finish has enough “give” to soak up that energy and stay intact.
