High-Penetration Infrared Preheating Lamps for Ultra-Thick Glass Cutting
Ever tried cutting ultra-thick glass the old way? Cold scoring just slams the cutting wheel with stress. You get micro-fractures, the wheel wears out fast, and the edges are all over the place. It’s a mess. So we built a preheating lamp that changes that. It lays down targeted infrared heat right along the cut line, prepping the glass before you even touch it.
Power, Voltage, and Size: What Actually Matters
Here’s the thing—we packed a lot of heat into a small footprint. The 400V supply keeps the current steady, so you don’t get voltage dips when you’re running long arrays on the line. The 2500W output? That’s what gives you the thermal punch you need—softening the surface on the spot, without waiting for the whole pane to heat up. And the 300mm tube length? It gives you a focused heating zone that lines up perfectly with a standard cutting lane. This isn’t a gentle heater. It’s high-intensity, and it needs space. Plan your cooling and clearances before you set it up.
Halogen Tech, Coating, and R7s Connectors
Inside, you’ve got a halogen-filled shortwave infrared source. Why? Because it responds instantly and hits hard when you need it to. The quartz envelope has a special coating that shapes the heat spectrum and keeps it from cracking under thermal shock. It also fights off grime buildup, which matters when you’re running long cycles. Then there’s the R7s connector. It’s direct, industrial, and no-fuss. Wire it, clamp it, and it stays aligned. If you’re tight on space, the Sk15 termination is available for specific fixtures.
How It Works: Softening the Path, Saving the Wheel
When you’re cutting ultra-thick glass, you run the lamp right alongside the cut line. The infrared energy sinks in and softens the glass locally, lowering the resistance right where you need it. That means the cutting wheel doesn’t have to fight as hard. Wheel life goes up, replacements drop, and the fracture starts clean. You get fewer edge chips, too. It’s a straightforward add-on to assisted cutting, but you’ve got to shield the surrounding parts and keep airflow in check. Otherwise, the nearby components will feel the heat.
