Stop Wasting Power on Your glass Annealing
Let’s be honest: annealing is usually the biggest energy hog in the whole production line. Most traditional heaters spend way too much time warming up the air around the glass instead of actually heating the glass itself. It’s a waste of money. We do things differently. We use shortwave infrared (IR) lamps that aim the heat directly at the workpiece. It cuts down your ramp-up time and, more importantly, shrinks your electricity bill.
Getting the Heat Right
If you want fast preheating, you need heat that actually punches through. We set up these lamps to deliver concentrated energy that sinks into the glass surface the moment it hits. Depending on how fast your conveyor is moving, we can tweak the wattage and voltage. The goal is to hit that critical annealing temperature perfectly—no guessing, and no overshooting. Plus, because high-wattage tubes pack such a punch, you can actually shorten your oven. You get the same thermal results with a much smaller footprint on your floor.
The Tech Behind the Glow
We use high-purity quartz envelopes because they can handle the shock of rapid heating and cooling without cracking. Here is the secret: shortwave radiation doesn’t rely on moving air (convection). It just hits the glass instantly. Depending on your setup, we can give you a sharp, focused beam or a softer, diffused spread. And don’t worry about a massive overhaul—these plug right into your existing controllers with standard industrial connectors. It’s a simple swap.
A Few Things to Keep in Mind
Now, switching to IR isn’t just “plug and play” without a plan. Since IR is directional, you have to be precise with where the lamps sit. If they’re off, you get cold spots. If they’re too close, you risk overheating a small area. You’ll also want to tweak your PID controllers. IR reacts way faster than old-school resistive heaters, so your settings need to keep up. Also, make sure your ventilation is on point. These things run 24/7, and you don’t want the housings getting too hot.
