Getting Those Massive Glass Sheets Right: The Truth About Long-Form IR Heating

Cutting oversized glass is a nerve-wracking process. If your thermal stress isn’t spot on, you’re looking at a lot of wasted material. The problem is that standard heating lamps just can’t keep up with huge sheets—you end up with cold spots that ruin the whole batch. That’s why we build custom infrared units that stretch over 2 meters. They’re made specifically for those long tunnel kilns where consistency is everything.

Getting Silk-Screened Glass Right During Tempering

If you’ve ever tried to combine silk-screen printing with tempering, you know it’s a bit of a tightrope walk. You need the ink to cure perfectly, but you can’t mess with the strength of the glass or let the pattern start bleeding. It’s a tricky balance. That’s why we lean on shortwave infrared (IR) preheaters to do the heavy lifting.

Keeping the Pattern Sharp

Here’s the problem with standard tempering ovens: they’re often too slow. If the glass heats up gradually, the ink can migrate, leaving you with a blurry mess. Shortwave IR lamps change that. They hit the surface fast. This creates a sharp temperature jump that sets the ink in place before the rest of the thick glass even realizes it’s getting hot. By tweaking the wattage and how you space the lamps, you can nail that curing temperature without pushing the glass to its softening point too early.
