If you’re running KraussMaffei VFFS systems and dealing with those massive rubber cord protectors, you’ve probably noticed that standard linear lamps just don’t cut it. Here’s the problem: when your rubber diameter is oversized, a flat lamp leaves gaps. You get hot spots and cold spots, and that’s a recipe for a bad part. Our fix is simple. We bend the quartz glass to match the exact radius of your workpiece. It hugs the curve. That means the heat hits the entire surface evenly, no matter how big the cord is. Getting the heat deep inside To get through thick rubber without burning the surface to a crisp, you need some serious muscle. We use heavy-gauge tungsten filaments that can handle the heat without flinching. But it’s not just about the power. It’s about the gap. By curving the emitter, we get it as close to the rubber as possible. Less air in the way means less wasted energy and a much faster warm-up. It just works faster. The nitty-gritty on materials We stick with high-purity quartz glass because it doesn’t crack when you cycle the temperature up and down quickly. For these specific setups, we use short-wave infrared (SWIR). Why? Because short-wave energy actually sinks deep into the rubber rather than just sitting on the skin. Depending on your setup, you can go with clear quartz for raw power, or we can add a gold coating. The gold reflects the heat back toward the part, which keeps your machine frame from getting baked. Plus, we use reinforced terminals, so you don’t have to worry about vibrations shaking your connections loose. A few things to keep in mind Now, these arc lamps put out a ton of heat, but they’re hungry. You’ll want to double-check that your power supply and cabling can handle the peak current draw. And since they run hot, your cooling fans or water jackets need to be spot on. If the housing isn’t venting properly, you’re basically cooking the lamp, which will kill its lifespan. We design these to be easy drop-in replacements, but just make sure the rest of your machine’s thermal management is ready for the ride.
