Getting Your KHS Heating Back on Track

If you’ve been dealing with uneven wall thickness or bottles that just look… off, you know the frustration. It usually comes down to heating uniformity. We see it all the time. A few old lamps burn out, someone swaps them for cheap replacements, and suddenly the thermal profile is a mess. You end up with bottles that deform because the heat isn’t hitting the preform evenly from top to bottom.

Getting Your SACMI IR Lamps to Actually Keep Up

When you’re running a high-speed PET line, you don’t have time to waste. In a SACMI rotary machine, everything happens in a heartbeat. A few milliseconds of lag in your heating can be the difference between a perfect bottle and one with wonky wall thickness or a cloudy finish. That’s why we built our IR lamps to hit the target temperature the second they switch on. No waiting around. Cutting out the lag Most generic quartz tubes have this annoying “warm-up” period. We hated that, so we focused on the thermal mass of the filament. By using high-density shortwave emitters, these lamps hit peak radiance almost instantly. Plus, they’re designed to handle high-frequency switching. You won’t see that annoying flickering, and you won’t be replacing burnt-out filaments every other week. They just work. The secret is in the glass We use high-purity fused quartz for the halogen cycle. It sounds technical, but here is what it actually means for you: the glass doesn’t soften even when things get incredibly hot inside. This lets us push more heat directly into the PET preform. And the best part? They’re drop-in replacements. The pins and the footprint match your SACMI sockets exactly. You just pop them in and go. No tinkering with the oven, no custom brackets, no headaches. A quick word of caution Here’s the thing: when you cram that much wattage into a short tube to get those fast cycles, it generates a lot of heat. That puts a bit more pressure on your cooling blowers. If your airflow isn’t moving that ambient heat away from the lamp ends, you’re going to fry your sockets. It’s a simple fix, though. Just check your ventilation filters every 500 hours. Keep the air moving, keep the lamps cool, and your line stays running without those nightmare unplanned shutdowns.

Can a simple lamp swap actually speed up your blow molding?

If you’re running an older blow molding machine, you know the struggle. The heating is inconsistent, the bottles aren’t coming out quite right, and you start wondering if the machine is just too old to keep up. But before you spend a fortune on a brand-new oven, look at your infrared (IR) lamps. Most of the time, the bottleneck isn’t the machine itself—it’s just worn-out heating elements. Swapping those old bulbs for high-density IR tubes is a quick way to get your heat distribution back on track. The secret is in the heat density. If you want to push more preforms through per hour, you need the heat to soak in faster. It’s a simple physics problem. By using higher wattage or adjusting the voltage, you’re basically hitting the PET wall with more radiant energy. The result? The preform hits its glass transition temperature way faster. You spend less time waiting and more time producing. What’s actually inside these things? We build these using heavy-wall quartz glass and halogen gas. Why the halogen? Because it stops the tungsten filament from evaporating. If you’ve ever seen a lamp go dark or cloudy over time, that’s why. These stay clear and stay hot. And don’t worry about the installation. We use standard R7s or SK15 connectors. They’re basically “plug and play.” You won’t have to tear apart your control cabinet or rewire half the factory. If the footprint matches, you can just swap them out during your next scheduled teardown and get back to work. A quick word of caution, though. More heat sounds great, but you can’t just crank it up indefinitely. If you put high-output lamps in an oven with clogged cooling fans or a weak airflow system, you’re going to have problems. You might end up overheating the neck of the preform, and suddenly your bottles are warping. It’s all about the balance. You want enough power to run the conveyor faster, but enough airflow to keep the plastic from melting where it shouldn’t. When you get that balance right, you can speed up your line and still keep your wall thickness exactly where it needs to be. It’s a mechanical fix that solves a production headache.

On a Krones stretch blow molder, preform heating is the line’s balancing act. If the heating tunnel doesn’t pull its weight, you get uneven wall distribution, flash, and the reject rate starts climbing. If the lamps spike or drift, you spend the day chasing temperature and watching energy costs creep up. The fix starts with the right Krones PET preform oven parts—specifically, infrared emitters spec’d to the machine.
