Stop Replacing Your SIG Blomax Heating Lamps Every Other Week
If your SIG Blomax line is eating through heating lamps, you’re probably frustrated. It’s a nightmare. Production grinds to a halt, your OEE tanking, and you’re spending way too much time swapping out parts. Most people think it’s a voltage issue. But usually? It’s just the physical stress on the quartz. These machines vibrate and heat up fast, and standard tubes just can’t keep up. That’s why we built our replacement heaters differently. We focused on the parts that actually break.
Why these tubes actually last
Standard quartz usually gives out at the pinch seal or where the electrode hits. It’s a weak point. We use a reinforced quartz blend that breathes better. It handles that constant “hot-cold-hot” cycle without cracking. We also tweaked the wall thickness and cleaned up the silica purity. This stops those annoying “hot spots” from forming—the kind that usually lead to a shattered tube. The best part? They’re drop-in replacements. You don’t have to mess with your wiring or move your reflectors. They just fit.
A quick word on heat and airflow
We tuned these for high-intensity shortwave radiation. You want your PET preforms to hit that perfect softening point quickly, without scorching the plastic. But here’s a heads-up: if you crank up the wattage to shave seconds off your cycle time, your cooling fans have to work harder. Just double-check that your oven’s airflow can actually get the heat out. If it can’t, you might warp your lamp holders, and that’s a headache you don’t need.
Getting them installed right
The secret to a long life is a tight connection. We use standard connectors, but you’ve got to make sure they’re clean and seated firmly. A loose fit causes arc-over, which can fry your end-caps in a matter of days. Clean the contacts. Snap them in tight. Pair that with our reinforced quartz, and you can finally stop worrying about when the next lamp is going to pop.
