Stop the Burn-Out Cycle on Your SIG Blomax Lines

If you’re dealing with tube burn-outs on your SIG Blomax lines, you know the drill. It’s frustrating. Every time a lamp pops, you aren’t just swapping a part—you’re staring at a dead line and losing money every minute the machine is quiet. Usually, this happens because the lamps just can’t handle the stress. We’ve spent a lot of time figuring out why, and we’ve built our PET preform heater lamps to actually hold up. Why standard tubes keep failing Most quartz tubes have a weak spot at the pinch seal or where they make contact. When you add vibration and the constant “hot-cold-hot” cycle of a production run, they just snap or leak. We changed how these are built. By beefing up that glass-to-metal seal, we’ve made them much tougher. It keeps the vacuum tight and stops the filament from oxidizing, which means the lamp actually lasts. Getting the heat right These are designed for high-intensity shortwave infrared. We’re obsessive about the wattage and voltage because if the heat profile isn’t consistent, your preforms suffer. But here is a pro tip: if you’re running high-wattage tubes, check your airflow. If your ventilation is sluggish, the heat just sits there and “soaks” the lamp ends. That’s a shortcut to a dead bulb. No headaches during install We made these “drop-in” replacements. You don’t have to mess with your wiring or tweak your reflectors. The connectors fit tight, too. No loose fits, no arcing at the terminals, and definitely no annoying flickering like you get with the cheap alternatives. You just put them in and get back to work. One last thing… Even the toughest lamp has a limit. High-density heating puts a lot of pressure on your power supplies. If your voltage is jumping around by more than 5%, it doesn’t matter how strong the quartz is—the lamp is going to wear out faster. Keep your power clean, and these reinforced tubes will take care of the rest.

Getting Your Husky HyPET Heating Right

If you’re running a high-speed Husky HyPET system, you already know that just cranking up the wattage isn’t the answer. It’s not about how much heat you throw at the plastic; it’s about where that heat actually goes. The real struggle is getting the center of the PET preform hot enough to blow without torching the outside. That’s exactly why we build our lamps the way we do. We make sure the heat hits the core and reaches that sweet spot—the glass transition temperature—right before the blow cycle kicks in. Getting the heat to soak in Most standard IR lamps just bake the surface. You end up with a preform that looks scorched on the outside but is still cold in the middle. That’s how you get “pearlescence,” and nobody wants that. We fix this by tweaking the quartz and the halogen filling to shift the spectrum. By focusing on medium-wave IR, the heat basically ignores the “skin” and dives deep into the thick parts of the base and neck. It’s a much more natural soak. Speed, power, and a word of caution When you’re running high cycles, you need a rapid ramp-up. Our tubes are built for that intensity. Plus, they’re a direct drop-in for the Husky footprint. You won’t have to mess around with your reflectors or tweak your hardware. But here is the thing: high power density creates a lot of heat—not just for the plastic, but for the lamp itself. Your cooling blowers are doing the heavy lifting here. If your airflow is choked or dusty, the lamp temperature will spike, and you’ll be replacing tubes way sooner than you should. Keep those blowers clean. The nitty-gritty of installation We use heavy-duty connectors because arcing at the terminals is a nightmare in a 24/7 shop. These lamps are built to take a beating, but they still rely on a good connection. A loose socket is a silent killer. It creates a hot spot that burns out the tube prematurely. When you’re wiring these in, double-check that the tension is tight. If the voltage drops across the line, your oven bank won’t pull an even load, and you’ll be chasing heating inconsistencies all shift.
