No warning, no impact. Just a crack. That&rsquo;s usually because of internal stress. If your heat swings by even a couple of degrees, you&rsquo;re playing Russian roulette with your work. You risk &ldquo;shivering&rdquo; during the cool-down, and that&rsquo;s a heartbreak you don&rsquo;t need. To stop that, we use high-precision infrared lamps. We don&rsquo;t just get close to the annealing point; we nail it and hold it with 0.1°C accuracy.</p>
