You can&rsquo;t exactly fit a massive industrial oven in a repair shop. That&rsquo;s why we use shortwave infrared (IR) lamps. Instead of wasting time heating up all the air in the room, these lamps shoot thermal energy straight into the glass. It&rsquo;s direct. It&rsquo;s fast.</p> <h2 id="the-power-struggle">The Power Struggle</h2> <p>Here&rsquo;s the thing about portable rigs: you can&rsquo;t just keep cranking up the wattage. You&rsquo;ll fry something. Instead, we focus on<strong>power density</strong>. We use high-wattage quartz halogen tubes but keep them small. This concentrates the heat right where it needs to be, so the glass hits that softening point quickly. But be careful with your power supply. If your voltage is limited, you&rsquo;ve got to play around with the filament length and diameter. Otherwise, you&rsquo;re just going to keep tripping your circuit breakers.</p> http://ir-heat-ray.com/en/posts/zoned-heating-for-glass-bending/ Thu, 25 Jun 2026 06:21:39 +0800 http://ir-heat-ray.com/en/posts/zoned-heating-for-glass-bending/ <p><img src="http://ir-heat-ray.com/images/0539f8d11cfcdd1efd2329f9dbab37bb.png" alt="Zoned heating for glass bending"></p> <p>On the bending line, the furnace doors swing open and you&rsquo;re instantly in a race against the clock. Glass moves from the heating chamber to the forming station, and every second the temperature drops, it shows up in the reject pile—optical distortion, shape drift, or a hairline fracture that only reveals itself later as failed tempering. When the heat profile is flat, the parts come off the line matching the drawing. When it&rsquo;s uneven, you&rsquo;re paying for scrap and rework.</p>
