Stop the Burn-outs on Your SIG Blomax Lines

If you’re running SIG Blomax lines, you know the frustration of a tube burning out right in the middle of a run. It’s a nightmare. Usually, it comes down to mechanical stress or just plain thermal shock. We got tired of seeing those unplanned stops, so we built a reinforced version of the preform heater lamps that can actually take the heat. Why do the standard ones keep snapping? Here’s the thing: PET preforms need to get hot, and they need to do it fast. To get that clean stretch-blow, we’re pushing high wattage through a very narrow quartz tube. That creates a massive spike in heat density. If the glass isn’t built for that kind of pressure, it cracks. Simple as that. We changed the quartz composition in our reinforced lamps so they can handle those wild temperature swings without just snapping. Built to actually fit Most lamps fail at the connector or the pinch point. We fixed that by shifting where the internal filament sits, which cuts down on the fatigue caused by vibration. And don’t worry about the setup. These are drop-in replacements. You don’t have to mess with your wiring or change your footprint; they fit the SIG Blomax specs perfectly. We also swapped in heavy-duty electrodes so you don’t have to deal with arcing or pitting when the line is humming along at full speed. One quick heads-up Now, these aren’t magic. They’re tougher than the OEM stock, but they still need a bit of love. Because these lamps hold onto heat better, your cooling fans have to be working. If your airflow is choked up with dust, the ends of the lamps will overheat, no matter how reinforced they are. Just keep your filters clean and you’ll be set. It’s a simple hardware fix. You get lamps that last longer, fewer teardowns, and a lot less stress on the floor.
