Getting Your Krones Contiform Heat Profiles Just Right

Let’s be honest: managing the heating oven in a Krones Contiform is always a bit of a balancing act. You want that heat density to be spot on, but you also don’t want to be swapping out lamps every other week. When your original IR radiators finally give up the ghost, you’re usually faced with two choices: pay the steep OEM price or find a replacement that actually works. We’ve focused on creating a drop-in option that hits the same spectral output without draining your budget. The deal with power and voltage These bulbs run on high-voltage circuits because you need a massive amount of wattage to get those PET preforms hot, and you need it to happen fast. We spec our lamps to match the original SMF radiators exactly. Why? Because packing high wattage into a short tube creates a concentrated heat zone. That’s how you get those faster cycle times. Just a heads-up: keep an eye on your power supplies. If you’ve got voltage spikes jumping around, your filaments are going to burn out way faster than they should. Quartz, connectors, and the “fit” We use heavy-wall quartz glass. It has to be tough to handle the thermal shock of rapid cycling without cracking. Plus, the halogen cycle keeps the tungsten filament from evaporating onto the glass, so the tube stays clear and the heat keeps flowing. Most of these use R7s or Sk15 connectors. We build these to very tight tolerances. You want them to slide into the sockets smoothly—no forcing required. If the fit is loose, you get an arc. And an arc will melt your socket right off the machine. Not a fun way to spend a Tuesday. Real-world tips for the shop floor These are direct replacements. They deliver the shortwave IR radiation needed to punch through the PET wall and get the job done. But here is the thing: keep an eye on your oven reflectors. Even with a perfect bulb, a dirty or misaligned reflector will create “hot spots” on your preforms. I always suggest cleaning the reflectors every time you change a lamp. It’s a simple habit, but it ensures the energy is actually hitting the plastic instead of just heating up the machine frame. It keeps your process stable and, more importantly, keeps your scrap rates low.

Sidel SBO 10 Series 1 infrared radiator

On a Sidel SBO 10 Series 1 line, the heating section is where the shift gets made or broken. If preform temperature starts drifting, you’ll see it immediately—weight swings, blown-out shoulders, and a scrap pile that quietly eats your margin. What you need is an infrared radiator that behaves like the original: same output, same response, same reliability. That’s what keeps the heating profile repeatable, shift after shift. What matters, technically The SBO 10 Series 1 infrared radiator is built around a short-wave quartz emitter, chosen specifically for fast thermal response and tight control inside the preform heating tunnel. It runs at 230V, with power matched to the machine’s heating-zone load so you don’t have to rework the control strategy. The quartz tube is dimensioned for the SBO 10 geometry and mounting, using an R7s-style interface and end-seal dimensions that line up with the reflector fixture. Peak wavelength is tuned for PET absorption, so the energy goes into heating the preform wall instead of being wasted as convective heat. Output stays stable over time, backed by field-verified run hours that keep the heating curve consistent. And the cold-start ramp is quick enough to support frequent recipe changes without long warm-up delays. Why it works in stretch blow molding In stretch blow molding, the preform has to hit a tight temperature window before it hits the mold. This radiator restores the OEM-intended heating balance: faster recovery after line stops, fewer hot spots, and less variability across cavities. The payoff is fewer rejects, more consistent bottle weight, and cycle performance you can count on. Energy use stays under control because the emitter delivers the required heat without overshoot. The matched design also cuts out the temptation to crank up power to compensate for mismatched lamps. What you need to watch on install and operation Installation is straightforward, but the details are where you earn it. Confirm the exact wattage and voltage for your SBO 10 Series 1 variant, and make sure the reflector is clean and aligned properly—misalignment shows up as banding on the bottle. Handle the quartz tube by the ends only. Any contamination on the tube surface will drive uneven heating and shorten service life. Infrared emitters are also sensitive to ambient drafts and cooling airflow; if your tunnel airflow is high, verify the temperature feedback loop so you don’t get oscillation. When the specs and mounting match the machine, you get repeatable heating with fewer lamp changes and less downtime.

Aoki blow molding IR radiator lamp bulb

On the blow molding line, uneven preform heating shows up immediately: off-center walls, blown bottles, and a heating tunnel that’s always chasing setpoints instead of holding them. On Aoki machines, that IR radiator lamp bulb isn’t just any bulb—it’s a matched thermal component, engineered to the machine’s heating profile.
