You need to get rid of those internal stresses so the glass doesn&rsquo;t shatter, but you can&rsquo;t warp the <a href="https://henruite.com">shape</a> of the bulb while doing it. The old way? Batch ovens. But let&rsquo;s be <a href="https://o-yate.net">honest</a>—they&rsquo;re slow. They kill your momentum. That&rsquo;s why we moved everything in-line using shortwave infrared (SWIR) lamps.</p> <h2 id="its-all-about-the-speed">It&rsquo;s all about the speed</h2> <p>Here is the thing about standard resistive heaters: they waste time warming up the air around the glass. It&rsquo;s sluggish. SWIR is different. It beams energy directly onto the glass surface. It happens almost instantly. We use lamps with high power density because when your production line picks up speed, you can&rsquo;t afford to sit around waiting for a heating element to cycle. You just tweak the power, and the heat flux adjusts in real-time. It&rsquo;s fast. Really fast.</p>
