Introduction
Let’s talk about a problem that’s been burning a hole in a lot of glass lines: how to temper glass right after silk-screening without wrecking the print. We built this quartz glass sleeve infrared heating lamp to solve exactly that. It gets the glass hot enough to lock in strength—without scorching the pattern. In other words, it finds that thermal sweet spot and stays there.
Technical Deep-Dive
Here’s the quick rundown: it’s a 400V, 2500W lamp with a 300mm active length. Why those numbers? Because you need serious power in a tight space. This setup hits high power density, so the glass surface climbs to tempering temperature fast. And the 400V? That’s chosen to plug straight into industrial power lines. Less fuss with step-down transformers. Less clutter. Just a clean, direct connection.
Material & Design
We wrap the heating element in high-purity quartz glass. Quartz is tough. It handles rapid heating and cooling without cracking, and it sends shortwave infrared energy through with real efficiency. Then there’s the R7s connector—the standard for this shape. It gives you solid, two-point contact that can carry high current without getting hot under the collar. The sleeve itself acts like a shield, standing up to thermal shock so the element stays protected while the glass does its thing.
Application & Benefits
In an integrated tempering line, this lamp delivers the heat profile you need to anneal the glass right after the silk-screening step. The shortwave infrared radiation reaches into the glass, heating it from within. That means you don’t get surface-only scorching that ruins printed patterns. It heats up quickly, too. That keeps the line moving. Now, with that kind of heat density, you do need to make sure your machine’s cooling system is up to the job. The area around the lamp gets warm, and you want to stay on top of that. But once it’s set, it’s a drop-in piece built for continuous duty—steady, reliable, and ready for high-volume glass tempering without second-guessing the process.
