You&rsquo;re running a long annealing tunnel, and everything seems fine—until you hit those gaps between the lamps. Most standard infrared lamps stop at 1.5 or 2 meters. That sounds like a lot, but in a long tunnel, those tiny gaps create cold spots. It&rsquo;s a nightmare. Those temperature dips create internal stress in the glass, and before you know it, your pieces are fracturing during the cooling phase. It&rsquo;s frustrating, and it&rsquo;s expensive. That&rsquo;s why we started building <a href="https://henruite.com">custom</a> heating units that push way past that 2-meter mark.</p>
