Stop Wasting Power on Your Glass Annealing

Let’s be honest: annealing is usually the biggest power hog in the entire coating line. Most traditional ovens are just inefficient. They spend half their energy heating up the air and the walls of the chamber instead of actually doing the work. We do things differently with shortwave infrared (IR) lamps. Instead of trying to heat the whole room, these lamps go straight for the glass.

Getting Your Glass Heat Right: The Struggle with Long Tunnel Kilns

If you’re heating glass for molding in a long tunnel kiln, you know the drill. You need the heat to be steady. No dips, no spikes. But here’s the problem: once your line stretches past 2 meters, those standard, off-the-shelf lamps start to fail you. You end up with these annoying “cold spots” right where the lamps meet. It’s frustrating, and it ruins the finish. That’s why we build ultra-long continuous infrared units. We basically get rid of the gaps so the heat stays even across the whole tunnel. The trick to scaling up You can’t just stretch a quartz tube and call it a day. If you do, the ends usually burn out while the middle is barely warm. It’s a mess. We fix this by playing with the filament winding and using high-grade quartz. It balances the power so the heat is the same from start to finish. For you, that means no internal stress and no random cracks in your glass during molding. It just works. Making it fit To get that “one long heat zone” feel, we design these units to sit tight, end-to-end. We use reinforced end-caps and precision connectors so the lamps sit flush. No gaps. No wasted heat. We usually lean toward shortwave emitters here. Why? Because they punch through the glass faster and deeper than medium-wave options. It means your glass gets soft and ready much quicker, which saves you a ton of time. A few things to keep in mind Just a heads-up: these long arrays pull a lot of power. You’ll want to make sure your electrical panels can handle the high current without tripping every ten minutes. And please,don’t mount them too tight. Quartz expands when it gets hot. If you bolt them rigidly into the kiln frame, they’ll snap under the pressure. Give them a little room to breathe. It’s a lot simpler than trying to juggle dozens of small, mismatched lamps that never seem to heat the same way. You get the high heat you need, and you can actually stop worrying about the temperature drops.
