Better Lamps for Your Krones and Sidel Blow Molders
If you’ve spent any time around a PET stretch blow molder, you know the headache of uneven heat. One minute everything is fine, and the next you’re staring at pearlescence or walls so thin they’re practically nonexistent. It’s frustrating. That’s why we make replacement lamps specifically for Krones Contiform 1/2 and Sidel lines. Whether you’re running old-school SBO units or the newer Matrix series, we’ve got you covered. Let’s talk power. Getting the wattage and voltage right isn’t just about following a manual—it’s about heat flux. If you throw in a lamp with the wrong resistance, you’re playing a dangerous game. You could fry your transformer or leave your preforms under-heated. We match the OEM electrical footprint exactly. The IR output hits the plastic at just the right frequency. Now, high-wattage tubes are great for speeding up your cycle times, but a word of advice: make sure your oven’s ventilation can actually handle the extra heat. If it can’t, those lamps are going to fail way sooner than they should. No tools, no fuss. Nobody wants to spend their downtime rewiring an oven. We build these for a “no-damage” install. The length and diameter are spot on. We use standard R7s or Sk15 connectors, so the lamps just slide right into your existing sockets. Simple. We also use quartz glass that can handle the shock of rapid thermal cycling. Plus, we’ve added specific coatings to shift the IR spectrum. This means the energy actually goes into the PET material instead of just heating up the machine frame. Real-world use. These are direct swaps. You can pop them in during your scheduled maintenance without messing with the lamp holders. We spec the filaments for high-stress environments because we know these machines take a beating from constant power cycling. Just one thing to keep in mind: the best lamp in the world won’t save you if your reflectors are misaligned. If those are off, your heating won’t be uniform, no matter what lamp you’re using. Keep your reflectors clean, pop these in, and you’re good to go.
