Stop the Headache of Broken Quartz Tubes in Your SIG Blomax Line

There is nothing worse than a line stop. You’re in the middle of a high-speed run, and suddenly, a quartz tube cracks. Everything grinds to a halt. Usually, it’s the same old story: thermal shock or just the constant shaking of the machine wearing the glass down. It’s frustrating, and frankly, it’s a waste of time. That’s why we stopped making “standard” tubes and started building ones that can actually take a beating. How we fixed the breaking point Most tubes fail at the seal or right in the middle because the heat isn’t spreading evenly. It’s like pouring boiling water into a cold glass—eventually, it snaps. We tweaked the wall thickness and used a higher grade of quartz to change how the glass handles expanding and contracting. Now, when your system jumps from peak power to standby, the tube doesn’t panic. We also beefed up the ends so the lamp doesn’t shift around when the machine starts vibrating at full speed. No need to rewire everything You don’t want a project; you just want a part that works. Our tubes are a direct swap. They fit the SIG footprint exactly, so you can just slide them in without messing with your racks or wiring. We use a specific type of quartz that lets shortwave IR radiation pass right through. This means the heat goes exactly where it needs to—onto the material—instead of soaking into your machine frame. One quick tip: keep an eye on your power supply. These tubes are tough, but if your voltage is jumping all over the place, any tube will die early. Keep your current stable, and these things will last. What this means for your day The biggest win here is simplyuptime. You stop worrying about the constant cycle of “break, replace, repeat.” Sure, because the walls are a bit thicker, they might take a few extra seconds to hit full temperature compared to the thin ones. But honestly? A few seconds of warm-up is a tiny price to pay for not having to shut down the whole PET line for an emergency repair. Just slide them in, wire them up, set your timers, and get back to work.

On the blow molding line, preform temperature is the tightrope. Too cold, and the bottle splits at the shoulder. Too hot, and you kill the PET molecular orientation—barrier performance goes with it. When the heating tunnel can’t hold setpoint, you don’t need a sales pitch. You need heat that repeats.

What actually matters under the hood

We build industrial quartz infrared lamps for preform heating in stretch blow molding. Short-wave output hits hard and fast, penetrating the PET wall quickly so the preform surface and core close the temperature gap within the tunnel dwell. We match OEM electrical and mechanical interfaces—R7s connectors, 240V/480V options, and exact quartz tube lengths and diameters. Power density is tuned to the heating zone profile: enough punch to recover fast after a jar change, yet stable enough to hold ±1°C control when the line settles in.
