Stop Wasting Power on Your Glass Annealing

Let’s be honest: cutting and annealing safety glass is an energy hog. If you’re still heating up the entire volume of an oven just to treat the glass, you’re basically paying to heat the air. We do things differently. We use shortwave infrared (IR) lamps that hit the glass surface directly. It’s the difference between heating a whole room with a furnace and just using a space heater right where you’re sitting. Your power bill feels the difference immediately because the energy actually goes where it’s needed. Getting the heat where it counts To get glass to that transition temperature quickly, you need some serious punch. We build our lamps with high watt-densities so they ramp up fast. The best part? You aren’t soaking your surrounding machinery in waste heat. Everything just moves faster. More sheets per hour, less waiting around. Just a heads-up: these tubes pull a lot of power. Make sure your wiring and control panels can handle the current draw. You don’t want to be tripping breakers right in the middle of a peak run. The gear inside We use high-purity quartz for the envelopes. Why? Because cutting rooms are brutal, and this stuff can handle the thermal shock without cracking. We also use a halogen cycle inside the tube to keep the filament from burning out too soon. It just lasts longer. And here is the real secret: shortwave IR actually penetrates the glass. It doesn’t just bake the “skin” of the sheet; it gets deep into the core. Getting it on your floor If you’ve got old, clunky resistive heaters, these are designed to slide right into those same footprints. It’s a pretty simple swap. Just wire them up to a PID controller and you’ve got total precision. One thing to keep in mind: shortwave IR is intense. You’ll feel that heat the second you’re exposed to it, so double-check your shielding and make sure your team has the right PPE. Also, be smart about where you place them—you don’t want to accidentally cook your conveyor rollers.

Getting the Balance Right: IR Tempering and Screen Printing

Here is the tricky part about combining screen-printing and tempering into one go: you’re fighting a constant battle. You need enough heat to bake the ink in, but if the surface gets too hot too fast, you’ll burn your pattern or shock the glass before it even hits tempering temperature. It’s a balancing act. And the secret weapon for fixing this? The distance between your IR lamps and the glass. The deal with lamp distance Shortwave IR lamps pack a serious punch. If you mount them too close, you get these nasty “hot spots.” They eat through your ink pigments and leave the stress distribution across the pane looking like a mess. I always suggest looking at the specific ink you’re using and calculating the distance based on what that chemistry actually needs. By widening the gap, you spread the heat out. It stops the surface from scorching and lets the heat soak deeper into the glass where it belongs. Watching the temperature climb You want the heat to be even. Simple, right? But it’s easier said than done. If the lamps are too tight to the glass, you risk “skinning.” That’s when the surface is screaming hot, but the core is still lagging behind. For this to work, you need a steady ramp-up. Adjusting that safety distance lets you control the climb, making sure the ink cures and the glass hits its softening point at the exact same time. The trade-offs Of course, there’s a catch. Pushing the lamps further away saves your patterns from burning, but it slows things down. Your glass will spend more time on the conveyor. To keep your speed up, you’ll probably need to bump up the wattage or throw in more tubes. Just keep an eye on your cooling system—if you crank the power to make up for the distance, your gear is going to feel that extra heat load. Push it too far, though, and you’re just wasting power and losing efficiency. It’s all about finding that sweet spot.
