Dealing with Tight Squeezes in Glass Bending Furnaces
If you’ve ever tried to get a clean break with thermal stress cutting, you know it all comes down to one thing: heat in exactly the right spot. But here’s the problem. If you’re working with a non-standard furnace, the layout is usually a nightmare. You try to plug in a standard infrared lamp, and it just doesn’t fit. It’s too long, too short, or the chassis is just weirdly shaped. You end up with these annoying cold spots and uneven heating that mess up your whole batch.
Why the shape actually matters
We solve this by building heaters that actually fit your space. No “close enough.” We’re talking exact millimeters. When the heater fits the opening perfectly, you get a wall of heat across the entire edge of the glass. It stops that frustrating “dipping” effect where the middle is scorching but the ends are barely warm. Plus, we can wrap the heating element around the specific curve of your workpiece. It keeps the temperature steady. That’s the only real way to stop those jagged edges or random cracks from ruining your day.
The catch with high-density heat
Now, there is a trade-off. If we cram more wattage into a shorter, custom tube, you get a massive boost in heat flux. Your ramp-up time drops. It’s fast. Really fast. But that puts a lot of pressure on the quartz envelope and the pins. If you go for extreme heat in a tiny space, you can’t ignore your cooling. You’ll need fans that can actually handle the heat around the housing, otherwise, you’re just waiting for your wiring to melt.
Just drop it in and go
We make these lamps as direct replacements. The length is right. The connectors match. You just wire them up and get back to work without having to rebuild your furnace frame. It beats the hell out of using makeshift brackets, which usually just end up crooked and leave you with the same uneven heat problems you started with.
