You&rsquo;ve got these massive sheets—often over 3 meters wide—and you need the heat to be perfectly even across the whole thing. Here’s the problem: standard, off-the-shelf infrared lamps just don&rsquo;t work for this. You end up with these annoying cold spots. And in this business, a cold spot means internal stress, which means the glass snaps. Not a great look. That’s why we build custom, ultra-long infrared heating units. We design them specifically to fit those wide baking tunnels so you don&rsquo;t have to worry about your glass cracking.</p>
