If you don’t manage thermal stress, the cut edge walks micro-cracks right into tempering, bending, or lamination, and those defects compound downstream. We set up the heating module to nail the surface temperature fast, so scoring is about predictable stress, not guesswork.</p> <h2 id="what-matters-technically">What matters, technically</h2> <p>The heart is a short-wave infrared emitter with a spectral response tuned to couple hard into glass—surface heat, fast, without driving the bulk. Keep the band tight—±2% across the active <a href="https://o-yate.com">length</a>—and the thermal front stays uniform, so expansion lines up along the score. It runs on 240 V or 480 V, drops into standard ceramic holders, and the quartz envelope takes repeated thermal shock without drama. The response is quick: full power in under 2 seconds, and the control takes 4–20 mA from your PLC so timing lands exactly where you want it. We’ve run units 5,000+ hours with less than 5% output drop, so stability holds shift after shift.</p>
