Why Your SIG Blomax Lamps Keep Blowing (and How to Fix It)

If you’re running a SIG Blomax line and your tubes are burning out way too often, you know how frustrating it is. It’s never just a “random fluke.” Usually, it’s because the lamps just can’t handle the vibration and the constant heat swings of a high-speed blow molding machine. They basically get shaken and cooked until they snap. The secret is in the glass. We’ve spent a lot of time rethinking the quartz envelopes on our replacement IR lamps. Standard tubes love to crack right at the pinch seal or the connection point because they can’t handle the thermal expansion. We fixed that by tweaking the wall thickness and using higher-purity quartz. It makes the lamp tougher, which means it lasts longer before it gives up. And the best part? They’re drop-in replacements. You won’t have to mess with your wiring or change your footprints. We keep the wattage and voltage exactly the same as the SIG OEM specs, so your heating profiles don’t skip a beat. A quick heads-up on heat. Shortwave IR lamps have to be incredibly intense to soften PET preforms in a fraction of a second. But that intensity creates a brutal temperature gap. Here’s the thing: if your cooling blowers are clogged or just aren’t cutting it, the ends of the lamp will overheat. That leads to the filament evaporating way faster than it should. A reinforced lamp is a huge help, but it only works if your airflow is dialed in. Getting them installed We use precision-fit connectors because arcing is a nightmare. A loose connection at the terminal is the fastest way to kill a brand-new tube. When you’re swapping these out, just make sure the contacts are clean and tight. Simple, but it saves you a lot of grief. By focusing on those structural weak points where SIG lines usually fail, we can help you stop those annoying line stops. Plus, you won’t have to keep a mountain of spare glass sitting in your warehouse just to survive the week.

Stop Overpaying for Krones Contiform Parts

Let’s be honest: OEM parts for a Krones Contiform line are expensive. Really expensive. When you’re just trying to keep the line moving, those price tags start to sting. That’s why we made a drop-in replacement lamp. It does exactly what the factory lamp does—hitting those specific infrared targets for PET preforms—but it doesn’t come with the “brand name” tax.

When the heating tunnel on your blow molder starts drifting, the whole line pays for it. You get slowed cycles and preforms that come out inconsistent. We build infrared heating assemblies to take that uncertainty out and give you repeatable heat profiles—and uptime you can plan around.

What matters under the hood

We use quartz infrared emitters that respond fast and hold steady across the preform heating window. Power is matched to the OEM voltage and watt density, so the curve plugs into your blow molding machine control without fighting it. The interfaces are practical: R7s sockets, the right lead lengths, and mounting brackets that keep the heating zone aligned. Emitter geometry is chosen to spread coverage evenly—no hot spots—and the reflector design puts the energy where the preform needs it, not bleeding off into the frame.

Out on the plant floor, one mismatched heater element in the preform heating tunnel is enough to stall the whole line. You get uneven stretch, bottles that blow out, and that mad scramble for a replacement that actually fits. We make OEM-grade PET blow molding heater elements that match the original specs for Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB machines. What we build, technically These are short-wave infrared lamps—quartz tubes with halogen filaments, sized for standard blow molder tunnels. Typical ratings run 1000–3000 W, 230/460 V, with lengths from 300 mm to 1200 mm. You get R7s connectors, and we can do custom terminals when the machine calls for it. Fast response and a focused spectrum get preforms up to temperature quickly, and stable resistance keeps power consistent across the heating profile. Why it plays in production Tight dimensional tolerances and repeatable watt density give you uniform preform temperature, so stretch blow molding runs the cycle it was designed for. You use less energy because the emitter turns more of the input into usable heat, and longer lamp life means fewer changeovers. On Sidel, Krones, and the rest, that means fewer rejects, steady output, and maintenance windows you can actually plan around. Here is the part that matters on the line Infrared heating is finicky—reflector cleanliness and preform spacing make a real difference. Set the lamp at the correct gap to the preform path, keep reflectors free of oxidation, and double-check voltage and connector match before you swap it in. In humid or high-dust environments, protect the lamp ends and verify the cooling airflow; that’s what keeps output stable and the lamp life honest.
