On the tempering line, edge heating isn’t a nice-to-have—it’s the difference between making yield and watching glass shatter at the quench. When the edge profile isn’t even, thermal stress builds right at the boundary. The press bends, re-bends, and still the glass gets rejected. We designed these edge heating lamps to break that loop. What matters under the hood They run on short-wave quartz infrared, delivering fast, localized heat with tight control over the thermal band. Power is matched to the line—typically 2–4 kW per lamp—so you can move from low-E coatings to thicker float without slowing the conveyor. Filament geometry and reflector layout are tuned to create a uniform thermal field across the edge. That uniformity is what keeps the sharp gradients from driving micro-cracks before the furnace even does its work. You get quick ramp-up, repeatable output, and stable emissivity behavior shift after shift. Why this works in tempering The edge is always the weak link. These lamps pre-heat the perimeter so the glass hits the furnace with a consistent edge temperature. That cuts the shock at the quench and improves optical flatness. The payoff is fewer roll-wave defects, fewer edge chips, and a higher first-pass yield. Energy use drops because the heat goes where it’s needed—right on the edge—instead of warming the whole sheet. Field-level details Compatibility is straightforward. We supply drop-in replacement kits for common glass machinery brands, with pre-wired connectors and mounting hardware to keep installation time down. One practical note: keep the quartz envelope clean. Dust and coating residues on the lamp surface scatter the infrared and can drift the temperature profile. A scheduled wipe and a simple air purge are small steps that keep the heating repeatable, day in and day out.

On an insulating glass line, edge sealant isn’t just “dried” — it’s cured by heat that hits the right spot, at the right time, with the right amount of energy. When the drying lamp can’t keep up, you feel it immediately: cycles drag, cure becomes inconsistent, and rejects climb. You’ll see bubbles along the spacer, weak adhesion on the primary seal, and thermal stress that can crack panes right when you least need it — during handling. We built our edge sealant drying lamp to take those variables off the table. It’s a purpose-built heating module for glass processors running IG units day in and day out, where line speed, yield, and repeatability are the only numbers that matter.
