Introduction
Let’s be honest—non-standard glass annealing furnaces are a pain. They’re cramped, awkwardly shaped, and standard heating elements just don’t fit. So we built our infrared heating lamps to fix that, specifically for glass container annealing. These aren’t off-the-shelf. They’re made from scratch—custom lengths, custom shapes—to match your furnace exactly.
Power and Dimensions: The Reality of Tight Spaces
In a compact furnace, you need serious heat in a small footprint. Our elements deliver that, getting the glass up to annealing temperature fast. The voltage and wattage are tuned to your control system, so they handle rapid on-off cycling without blinking. And the length? That’s the key. No more wrestling a 1-meter tube into a 600mm gap. We build the element to your exact dimensions, so the heat profile lines up with the glass path. No cold spots. No overheating. Just clean, even heat. But here’s the trade-off: these elements run hot, because they’re tightly coupled to the work. That means your furnace’s cooling and insulation need to be up to the task—designed to handle concentrated energy, not just tolerate it.
Material and Design: Built to Take the Heat
We use quartz tubes with a specialized infrared coating, tuned to shine in the short-wave spectrum. That’s what makes glass heat up quickly and evenly. Inside, halogen fill gas keeps performance steady, even after thousands of cycles. Then there are the connections. We use rugged terminals—R7s or Sk15—that handle high current without getting sloppy hot. They make wiring straightforward, stay secure, and keep the contact clean and low-resistance. In other words, they’re made for the factory floor, not a white-glove lab.
Installation and Payoff: Fit First, Fiddle Later
The biggest win is installation. Because the element is custom-shaped to your space, it drops right into the tight spots. No major furnace modifications. No endless engineering headaches. Less downtime. Less head-scratching. And the focused infrared output gives you uniform heating across every glass container. That uniformity is what makes stress relief during annealing work the way it should—smooth, consistent, reliable. Bottom line: we build the element to your space, so you get the performance you need without rebuilding the machine.
