Stop the Constant Lamp Burnouts on Your SIG Blomax Lines
If you’re running a SIG Blomax line, you know the headache of lamps popping at the worst possible time. It’s usually a mix of mechanical stress and thermal shock. One tube snaps, the line stops, and suddenly you’re losing hours of uptime. It’s frustrating. That’s why we built our PETC preform heater lamps differently. We didn’t just copy the original; we redesigned them specifically to survive the chaos of a high-cycle environment.
Why standard tubes keep snapping
Most quartz lamps have a “weak spot”—usually right at the pinch seal or where the electrode meets the glass. That’s where they crack. We fixed that. By tweaking the wall thickness of the quartz and cleaning up the geometry of the seal, we made a lamp that can actually take a beating. Here’s the secret: it’s all about the heat. When there’s a massive temperature jump between the hot center and the cold ends, the glass stresses out and breaks. Our design spreads that heat load more evenly, so the glass stays happy.
The nitty-gritty on power
These are high-wattage, short-wave infrared emitters. The best part? They are total drop-in replacements. No hacking your machine or changing your wiring. They fit exactly where your old ones did. You’ll get that intense heat density needed to soften preforms fast. But a quick heads-up: because these tubes are reinforced and push a lot of power, your reflectors have to do more work. **Keep your reflectors clean.**If they’re dusty or charred, the heat bounces straight back into the lamp ends and bakes them. That’s the fastest way to kill a perfectly good tube.
Getting them running
We use standard connectors, so you can wire these up and get back to work without any fuss. Since these are built to last longer, you’ll spend a lot less time dealing with unplanned stops. Just do me a favor and check your voltage stability. A nasty power spike will fry any lamp on the market, no matter how tough the quartz is. Keep your power steady, and these tubes will keep humming along for a long time.
