Getting the Voltage Right for Your Glass Bead Annealing

If you’re annealing glass beads, you know the drill: you need a perfect thermal soak to get rid of those internal stresses. We build the infrared lamps that make this happen on high-speed lines. But here’s the thing—the hardest part of the job usually isn’t the heat itself. It’s the power grid you’re plugging into.

The Headache of Different Power Grids

Industrial plants are all over the map when it comes to electricity. A machine built for a US shop (110V) is a paperweight in a Canadian plant (575V) or a European site (400V/480V). You can’t just plug it in and hope for the best; you’d have to tear out the heating elements and start over. We handle that mess for you. We customize the filament winding and the thickness of the quartz tube so it actually matches your local power. Why does this matter? Because if you accidentally drop a 110V lamp into a 480V circuit,poof. The filament burns out instantly. On the flip side, if you under-volt a lamp, you won’t get enough heat density. Your beads won’t anneal properly, and you’ve just wasted a lot of time. We dial in the wattage and voltage so you hit your target temp without blowing a transformer.
