If your brake pads are squealing, the problem probably started way back in the curing oven. Here’s the deal: when friction materials don’t cure evenly, you end up with internal stress and weird density gaps across the pad. We see this all the time with old-school convection ovens. The surface hardens too quickly, which basically traps moisture and gases inside. It creates a “skin” that makes the pads wear down unevenly and—you guessed it—make a racket when you hit the brakes. Getting the heat where it actually matters To fix this, we use shortwave infrared (IR). Instead of relying on hot air to slowly soak into the part, IR energy goes straight into the material. The photons dive deep into the composite, meaning the core of the pad hits the right temperature at the same time as the surface. It makes the whole polymer process uniform. No more density gaps, no more vibrations, and no more noise. The trade-off Now, to get that kind of penetration, you need some serious power. We use high-wattage IR emitters because you need a lot of heat flux to punch through that dense material. But there’s a catch. Those high-density arrays put off a ton of ambient heat. If your fans or vents aren’t up to the task, you’re going to have problems—like warped jigs or a ruined conveyor belt. You have to plan for the waste heat. What this actually does for your shop The best part? It’s fast. Since you’re heating the part directly rather than waiting for the air to warm up, the curing cycle shrinks. That means you can actually make your oven footprint smaller. Plus, when your thermal profiles are consistent, you stop throwing so much scrap in the bin. When a pad is cured perfectly from the core to the surface, the friction stays stable. That’s how you kill the noise before it ever leaves the factory.
