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.

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.
