Stop Overpaying for Your Krones Contiform Lamps

Let’s be honest: OEM parts are expensive. If you’re running a Krones Contiform line, you know exactly what I mean. The costs add up fast, and it starts to feel like you’re paying a premium just for the brand name on the box. We decided to fix that. We make IR blowing lamps that do the exact same job as the factory ones—delivering that precise shortwave heat to your PET preforms—but without the massive markup. The nitty-gritty on power These aren’t your average lightbulbs. They’re built for high-voltage industrial environments. We’ve dialed in the wattage-to-length ratio so the heat hits exactly where it needs to. If you’re running a 400V system, you need filaments that can actually handle the load. We use heavy-duty tungsten because it stays stable. It doesn’t just flicker or burn out the moment things get intense. But a quick heads-up: high wattage means they ramp up fast. Just make sure your cooling blowers are actually doing their job. If your airflow drops, these lamps will cook the PET, and you’ll end up with those annoying burnt zones or that cloudy pearlescence in your bottles. Glass and connectors that actually last We use high-purity quartz glass. Why? Because it doesn’t soak up the IR energy itself. Instead, it pushes all that heat outward, straight into the preform. For the connectors, we stick with R7s or Sk15. They handle the “breathing” of thermal expansion much better than a soldered joint ever would. Plus, we offer coated versions. These act like a mirror, bouncing the heat back toward the center of the oven instead of letting it waste away against the machine walls. Getting them into your machine Swapping these in is easy. You wire them up exactly like the original parts. We’ve kept the tolerances on the diameter and length tight, so you won’t be fighting to get them into the lamp cages. No forcing, no jamming—they just fit. Now, look, these tubes take a beating in a 24/7 production cycle. That’s just the nature of the beast. While we build them to hold their output for thousands of hours, the filament will eventually age. That’s normal. But by switching to our versions, you’re cutting your maintenance costs way down without sacrificing the quality of your bottles.

Getting Your Husky HyPET Heating Right

If you’re running a high-speed Husky HyPET system, you already know that throwing more wattage at the problem doesn’t always work. In fact, it usually makes things worse. You end up scorching the outside of the plastic while the core stays cold. That’s where we come in. We build custom IR modules specifically to kill off those annoying “cold spots” and uneven walls that plague high-speed blowing.

Getting Your Sidel SBO and Matrix Lamps Right

If you’ve ever dealt with PET blow molding, you know the headache of preform deformation. It all comes down to heat. If your thermal profile is off, your bottles are off. That’s why we build shortwave infrared lamps specifically for Sidel systems—everything from the old-school SBO lines to the newer Matrix series. The fit has to be perfect. Here’s the thing: Sidel machines aren’t all built the same. The oven footprints vary, and that makes replacements tricky. We build our lamps to match the OEM specs exactly—both the physical size and the electrical load. Whether you’re running 230V or 400V, we match the wattage so your heat flux stays steady throughout the cycle. We use high-purity quartz glass because these things take a beating from constant thermal cycling. And we’re obsessive about the measurements. If a lamp is off by even a single millimeter, or the end-cap spacing is slightly skewed, you’re looking at a mechanical clash during install or a loose connection. Nobody wants that. We keep the tolerances tight so you can just slide them in and go. It’s more than just “plug and play” We use specialized coatings to shift the emission spectrum. Why? Because we want the heat to actually penetrate the PET wall, not just scorch the surface. To keep things moving fast on the floor, we stick with standard R7s and SK15 connectors. Now, a word of caution. High-wattage tubes are great for fast cycle times, but they put a lot of stress on your reflectors. Check your reflectors before you swap the tubes. If they’re pitted or oxidized, a brand new high-output lamp is just going to waste energy—or worse, overheat your housing. It’s a quick check that saves a lot of trouble later. Making life easier at the plant If you’re doing a full plant overhaul, buying in bulk is the way to go. It kills the downtime. The best part? We’ve made these compatible across the whole Sidel range. You don’t need a dozen different SKUs for a dozen different machines. You just plug them in, tweak your temperature controllers, and get back to work. No need to modify the oven frame or mess around with the hardware. It just works.

Ideal temperature for PET preform blowing

On the blow molding floor, the heating tunnel is where the whole run lives or dies. If preforms come out at 90°C instead of the sweet spot—105–115°C—you’re staring down haze, weak stretch, and scrap that climbs fast. Let the lamps chase the setpoint and overshoot, and you’re burning polymer, wasting energy, and burning through lamp life. We built this infrared upgrade to break that loop. What matters under the hood We match the OEM heating profile with short-wave infrared emitters tuned to how PET actually absorbs heat. The quartz envelope runs at 220–240 V, hits standard R7s connectors, and drops straight into Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB tunnels without rewiring. Power density is set so the preform surface hits target quickly while the core stays even—no hot spots, no cold bands. Response is quick, too: the lamp hits stable output in seconds, so setpoint changes track without lag. Stretch blow molding lives and dies on temperature control. With this emitter upgrade, you sit inside the ideal preform temperature window more consistently, so parison stretch is uniform and you can trim bottle weight without giving up strength. On the floor, that shows up as 3–5% less scrap and a 4–6% cycle-time gain on 0.5 L bottles, because the heating tunnel stops fighting variability. Heating-block energy drops 8–12%, and lamp life stretches to 5,000+ hours, which means fewer changeouts and less downtime. Here’s what to watch for It’s plug-and-play only when the reflector geometry and lamp spacing match your blow molder’s tunnel. If you run at very high line speeds, double-check the power rating per zone to keep the temperature band tight. Plan on a 30-minute tunnel recalibration after the first changeover to lock in the new profile.
