Getting Glass Annealing Right Without Slowing Down

If you’ve ever dealt with glass annealing, you know the struggle. You need a perfect temperature profile to get rid of those internal stresses, but you can’t let the glass warp or deform. The problem? Most convection ovens have this annoying thermal lag. They’re just too slow. That’s why we use fast-response infrared (IR) lamps. They hit your target temperature almost instantly.

Why IR actually works

Here’s the thing: traditional resistive heaters spend way too much time warming up the air around the glass. It’s inefficient. IR lamps are different. They send energy straight to the glass surface via radiation. It’s direct. If you’re switching between different glass thicknesses on the fly, these lamps react in milliseconds. You don’t have to deal with that dreaded “ramp-up” time that usually kills your production speed.
