One tiny mistake, and the whole batch is ruined. That&rsquo;s the world we live in. So we built an electric glass lehr heating system for these environments. The heart of it is a high-precision infrared heating element, designed purely for the delicate job of annealing glass. The goal is straightforward: apply heat just right to wipe out the internal stress inside glass containers, without creating new cracks. It&rsquo;s a balancing act that ordinary heaters just can&rsquo;t handle.</p>
