Tired of swapping out burnt-out tubes on your PET lines?

If you’re running SIG Blomax or Krones Contiform S lines and feel like you’re replacing lamps every other week, you know exactly how frustrating it is. It’s usually a battle against thermal stress and those annoying voltage spikes. We got tired of seeing that cycle of constant downtime, so we built structural reinforced IR lamps. They’re designed as drop-in replacements—meaning you just pop them in and get back to work. The heat problem Here’s the thing: PET blowing is a balancing act. You need intense shortwave radiation to soften the preform, but if you overdo it, you scorch the plastic. To get that heat, you need high wattage. But that puts a massive amount of pressure on the quartz envelope. If the lamp can’t handle that expansion and contraction, it just snaps or burns out right at the electrodes. It’s a physics problem, plain and simple. How we actually fixed it We didn’t just make another bulb. We used heavy-wall quartz glass and beefed up the electrode junctions. Most cheap alternatives fail at the end-caps. Ours don’t. We also leaned into the halogen cycle to keep that tungsten filament from evaporating too fast, which keeps the lamp running much longer. Plus, we stuck with standard R7s or Sk15 connectors. No fancy mods, no rewiring your sockets. It just fits. Real talk from the shop floor These lamps take a beating. They’re tougher than the OEM parts, and you’ll definitely see more hours between swaps. But I’ll be honest with you: a better lamp can’t fix a broken cooling system. If your oven airflow is clogged, that heat is going to soak back into the socket and melt your wiring, no matter how good the bulb is. While you’re at it, give your reflectors a good clean. It ensures the energy actually hits the preform instead of just baking the lamp housing. We built these for 24/7 production. Because when you’re running at full tilt, every minute the line is down is just a bunch of bottles you didn’t make.

Getting the Heat Right: Sidel Matrix Lamps

Here is the problem when you swap out OEM lamps in a Sidel Matrix machine: you risk messing up your temperature curve. It sounds like a small detail, but if the heat density is off by even a tiny bit, you’re in trouble. You start seeing thin walls, uneven preforms, or that annoying pearlescence in the PET. It’s a headache you just don’t need. That’s why we build our replacements to mirror the original electrical and spectral footprint. Exactly. The science of the “Heat Curve” To keep things identical to the original, we obsess over the wattage-to-length ratio. See, a lamp isn’t just about how much total power it pulls. It’s about where that heat actually hits the preform. We spec our filaments to match the OEM’s ohms and voltage requirements perfectly. Why? Because if the IR radiation wavelength shifts, the PET doesn’t soak up the energy the same way. Your heating zones start to drift, and suddenly your bottles aren’t coming out right. Fit and Finish We use high-purity quartz glass. It’s tough. It handles those high-intensity cycles without burning out early. And they’re true drop-in replacements. We use the same connector footprints—whether you’re dealing with an R7s or a specific Sidel pin—so you can just wire them up. No hacking away at the oven housing. No “making it fit.” It just works. Plus, we have coated options if you want to sharpen that heat distribution. It pushes the beam forward and stops waste heat from soaking into the machine frame. It keeps the oven internals cooler, though it does put a bit more stress on the quartz. A quick word of caution High-wattage lamps are great for fast cycle times because they give you that raw heat density. But there’s a trade-off. Pushing more power through a small space puts a lot more pressure on your cooling blowers. If your cooling system is clogged or just tired, these lamps will run hotter than they should. That kills the filaments faster. Keep your airflow clean. It’s the easiest way to make sure your tubes actually last.

Replacement lamp for KRONES Contiform S

On a Contiform S line, the heating tunnel is where the whole cycle gets its rhythm. Underheat the preforms, and you’ll see weak shoulders, blown seams, and scrap piling up. Overheat them, and you get crystallization and ambering. As the lamps age, output drifts and temperature uniformity falls apart. The fallout isn’t just bad bottles—it’s unplanned downtime while you chase setpoints. What matters under the hood We built the Contiform S Replacement lamp to match the machine’s heating geometry and electrical envelope. The emitter is a short-wave infrared halogen lamp in a quartz envelope, chosen for fast response and stable output during the preform soak window. It’s spec’d to the OEM voltage and power draw so the heating curve stays repeatable across cavities. The base uses an R7s connector, and the overall length matches the original, so it drops straight into the existing reflectors and mounts without any fuss. We control spectral output and filament position to keep the energy profile consistent, so you get the same heat distribution you expect from the factory setup. Why it holds up in stretch blow molding Timing is everything in stretch blow molding. The lamp’s fast start-up brings the tunnel back to temperature quickly after a short stop, which cuts warm-up waste. Tighter temperature control improves bottle weight consistency and lowers burst failures on sensitive designs. In practice, plants running this lamp see fewer lamp-related alarms and more stable line speeds. Energy use trends lower, too, because the reflector alignment and output match the original system—no efficiency loss from mismatched emitters. A few shop-floor notes Installation is straightforward, but alignment is not optional. A lamp that isn’t seated right, or a reflector that’s worn, changes the heating pattern and can create hot spots. Always handle the quartz envelope by the base, not the glass, and make sure the orientation matches the arrow on the holder. Also, match the lamp to the exact Contiform S heating module; using a generic length or connector will shift the focus and degrade heating uniformity. Plan replacements during scheduled maintenance windows to avoid temperature swings that stress the preforms.
