Getting Heat-Shrink Right for Aircraft Wiring

When you’re dealing with aviation wire bundles, you’re walking a thin line. You need the heat-shrink tubing to snap into place quickly, but if you push it too far, you’re in trouble. Overheating the insulation can lead to dielectric breakdown or just plain warping. It’s a nightmare. That’s why we use shortwave infrared (IR). It lets us hit that perfect shrink temperature without cooking the wires inside.

Why IR actually works

Think about a standard convection oven. It heats the air, then the air heats the part. It’s slow. Worse, it’s uneven. IR is different. The lamps send out radiation that goes straight through the sleeve and hits the polymer. The sleeve shrinks fast, but the inner wiring stays cool. You get a tight, professional seal without worrying about burning out your insulation.

Stop Fighting Dust: A Better Way to Cure Aircraft Paint

If you’ve ever spent hours prepping a fuselage only to find a dozen tiny dust specks staring back at you after it comes out of the oven, you know the frustration. Standard convection ovens are basically giant vacuum cleaners. They blast hot air everywhere, and in the process, they suck up every bit of grit and dust from the shop floor and pin it right into your wet paint. It’s a nightmare. We found a way around this by ditching the forced air and moving to infrared (IR) drying lamps. How it actually works Here is the thing: IR lamps don’t bother with the air. They use electromagnetic radiation that goes straight through the paint and heats the aircraft skin itself. Since there’s no wind blowing around the hangar, the dust just stays where it belongs—on the floor. You get that mirror-smooth finish without having to turn your entire shop into a surgical operating room. Getting it set up We use short-wave IR emitters. These hit the surface hard and fast, which kicks the paint’s chemical curing process into high gear. Depending on what you’re painting, you can scale the setup. For those massive fuselage panels, we just use modular arrays. It keeps the heat even across the whole surface. And a nice little bonus? Because the lamps heat the metal and not the air, your HVAC system isn’t fighting a losing battle to keep the hangar cool. The “Gotchas” Now, it’s not just “plug and play.” You have to be careful. These lamps pack a serious punch of energy. If you try to wire them into a basic circuit, you’re going to have a bad time. You need a dedicated power controller, otherwise, you’ll burn out the lamps the second you ramp them up. You also have to get your spacing right. If the lamps are uneven, you’ll end up with “zebra striping”—those annoying uneven cure lines in the paint. A little bit of calibration on the distance between the lamp and the skin is all it takes to make sure you don’t scorch the coating.

Using Shortwave Infrared Lamps for Aircraft Window Frame Coating Removal

Getting Rid of Aircraft Coatings with Shortwave IR

A lot of guys in the shop see an infrared lamp and think, “Oh, it’s just a fancy hair dryer.” But when you’re dealing with window frames, that’s a mistake. We aren’t trying to dry anything here. We’re using shortwave IR to basically shock the old coating right off the metal.

The trick to fast stripping

If you want to get old paint or sealant off without warping the frame, you can’t just slowly warm it up. You need a hit of high heat, and you need it now. The cool thing about shortwave IR is that it dives straight through the coating and turns into heat right where the paint meets the metal. You hit a specific temperature, the bond snaps, and the coating blisters. From there, you just peel it away. If you just hover over the surface trying to “dry” it, you’re just wasting electricity and risking overheating the rest of the airframe.
