Getting Your Sidel Blomax Lamps Right

If you’ve spent any time working with Sidel gear—whether it’s an old-school SBO or the newer Matrix series—you know that heat is everything. It’s a balancing act. If your heat profile is off, your whole day gets a lot harder. That’s why we built our replacement lamps for the Blomax 4 to be total “plug-and-play.” No messing around with your oven reflectors. No rewiring your controllers. You just swap them in and get back to work. The struggle with heat signatures Here’s the thing about PET blowing: it’s picky. If your lamp length or wattage is off by even a tiny bit, you’re going to see thin spots in the bottle walls or, worse, unblown resin. It’s frustrating. We spec these lamps to match the original OEM voltage and wattage exactly. Why? Because we want that infrared wavelength to hit the preform exactly how it’s supposed to. You shouldn’t have to spend three hours tweaking machine settings just to get a stable blow. It should just work. Fit and finish There’s nothing worse than a lamp that doesn’t quite sit right. We use standardized connectors so these slide right in. We also locked in the physical dimensions. If a lamp rattles or sits crooked in the housing, you get hot spots. Those hot spots burn the preform, and suddenly you’re dealing with scrap. To stop that, we use high-grade quartz glass that can handle the constant “hot-cold-hot” cycle of a production line without cracking. A quick reality check Now, a word of advice from the floor. High-wattage infrared lamps pull a lot of power and they put out a ton of waste heat. Keep your oven cooling fans clean. Seriously. If your airflow is choked, the housing will overheat. When that happens, your filaments will burn out way faster than they should, no matter how high the quality of the lamp is. We’ve put these through the wringer across the whole Sidel range. They can handle the vibration and the heat of a high-speed floor without giving up on you.

Stop Fighting Your Oven: Fixing Heat Fluctuations in Rotary Blow Molding

If you’re running high-speed PET lines—especially those SIG Blomax 6 or SIPA rotary machines—you know the headache of uneven preform heating. One minute everything looks great, and the next, you’ve got wall thickness issues or bottles that just look… wrong. Most of the time, the culprit is “power drift.” It happens when you swap in replacement lamps that don’t actually match the original OEM specs. It sounds like a small detail, but it’s a huge problem. Why “Close Enough” Isn’t Good Enough Here’s the thing: infrared heat is picky. If your machine expects a specific voltage and wattage, but you pop in a lamp that’s off by even 5%, the heat spectrum shifts. Suddenly, you’ve got cold spots in your preforms. We build our lamps to hit 100% power parity. We obsess over the filament density and the thickness of the quartz so the heat stays consistent from one end of the tube to the other. No gaps. No surprises. The Gear We use a high-grade quartz envelope because these things take a beating with all that rapid thermal cycling. And because nobody wants to spend their weekend rewiring sockets, we use standard R7s or SK15 connectors. They just slide right in. Plus, we’ve calibrated the halogen cycle to stop the filament from evaporating. Cheap lamps usually fail here—they either burn out way too early or just start losing their brightness after a few hundred hours. Ours actually last. Real Talk from the Shop Floor When your power is matched, the “hunting” stops. You know what I mean—that frustrating cycle where your operators are constantly tweaking the oven settings just to keep up with aging tubes. It’s a waste of time. One quick tip, though. When you’re pushing these lamps to their max, your cooling blowers have to work harder. If your fans are clogged with dust or starting to fail, the oven gets too hot, and you might end up overheating the preform necks. Keep your airflow clean, and these lamps will do the heavy lifting for you.
