Before the parts even have a chance to stick together. The star of the show? The shortwave infrared halogen lamp. It puts the heat right where you need it—on the coating—without turning the whole glass substrate into a hot potato. A typical unit runs at 400V, 2500W, with a 300mm tube. That power isn&rsquo;t random. It’s exactly what’s needed to spike the surface temperature fast, hitting that sweet spot where solvents vanish without overheating the glass underneath. The 400V supply keeps the current manageable, so you can run several modules without rewiring the entire line. And the 300mm length? It’s just a practical size—fits neatly into <a href="https://henruite.com">existing</a> print-and-dry setups.</p>
