On the glass line, heat isn’t just a setting—it’s the bottleneck. If the bending heater starts drifting, you’re dealing with inconsistent sag, edge waves, and thermal stress that shows up later as breakage. Keep the heat profile stable, and the whole line moves like it should. We built this bending heater to hold that profile, shift after shift. What makes it work It uses short-wave infrared elements in a quartz envelope, so you get fast response and high power density without cranking up convection. The emitters are laid out to create a uniform thermal field across the glass—the only way to control shape and keep optical distortion down. The output is spec’d for industrial duty, with solid termination points and standard mounting geometry so it drops straight into existing bending furnaces and preheat stations. The control is clean: tight temperature tolerance, quick ramp-up, and predictable cool-down. Here is why it matters on the floor. In hot bending, the heater has to hit the transition temperature fast and hold it even; otherwise the glass flows unevenly and you spend the shift chasing scrap. In tempering preheat, uniform heating keeps localized thermal stress from cracking glass before it even reaches the quench. For lamination and coating drying, the heat has to penetrate without scorching the interlayer or skinning the coating. This heater gives you that control, shortens cycle time, and cuts energy draw per part. A few practical notes. Installation is straightforward, but you still need proper clearance and reflector alignment to hit the stated thermal profile. Expect higher peak power during ramp-up—size your supply accordingly. On high-humidity lines, keep the termination area protected; heat plus moisture will eat connections. Units are running 5,000+ hours with stable output, and we still recommend periodic emissivity checks and calibration to keep the process in spec.
