Anyone can click &ldquo;order&rdquo; on a part number. But if you&rsquo;re dealing with lamps that keep blowing out on your tempering line, you don&rsquo;t have a procurement problem. You have an engineering problem. Too many shops treat these lamps like lightbulbs—just something you swap out when they pop. But the real culprit is usually a mismatch between the lamp&rsquo;s heat and the thickness of the glass you&rsquo;re actually running.</p> http://ir-heat-tube.com/en/posts/rapid-preheating-for-glass/ Wed, 08 Jul 2026 23:27:22 +0800 http://ir-heat-tube.com/en/posts/rapid-preheating-for-glass/ <p><img src="http://ir-heat-tube.com/images/188f9035a5ed66fdec335fe67762e522.png" alt="Rapid preheating for glass"></p> <h2 id="introduction">Introduction</h2> <p>When you&rsquo;re annealing lab-grade glass, you&rsquo;re not just throwing heat at it. You&rsquo;re trying to gently coax out all the internal stress. That&rsquo;s why we built this system around a rapid-response infrared emitter—it was designed from the ground up for one thing: precision. The heart of it all is an infrared element that holds the temperature within a hair of 0.1°C. That kind of control is what keeps your sensitive glassware from cracking under the pressure.</p>
