Step up to the cutting table and you see it right away: micro-cracks that show up after scoring, or chips that snowball when the brittle zone is too cold. A conventional heater gives you hot spots and lag, and you end up either slowing the line or paying for it in scrap.</p> <h2 id="what-matters-under-the-hood">What matters under the hood</h2> <p>We built the thick-glass cutting preheater around short-wave infrared quartz emitters. The reason is simple: fast response and high power density, without leaning on heavy convection. The module runs on 380–480 V three-phase, pulls 24–36 kW depending on beam width, and lays down a uniform thermal field across the glass width—±3% temperature spread. Closed-loop control keeps the setpoint within ±5°C, so the surface hits the preheat target quickly and consistently. The emitters are rated to 5,000+ hours with controlled lumen decay, and the reflector geometry keeps the energy on the sheet, not bleeding off into the surroundings.</p>
