Getting Your Krones Contiform Oven Just Right
Let’s be honest: managing the oven on a Krones Contiform is always a bit of a balancing act. You want enough heat to get the job done, but you don’t want to burn through your lamps every few weeks. And when you look at the price tag for OEM replacements, it starts to feel like a robbery. That’s where we come in. We provide certified replacement lamps that do exactly what the originals do—same spectral output, same electrical load—just without the corporate markup. The electrical side of things These lamps live in a high-voltage world. If the wattage or voltage is even slightly off, your power controllers might start acting up or tripping entirely. Worse yet, a mismatch in resistance usually leads to two things: lamps that burn out way too early and preforms that heat unevenly. We focus on concentrated short-wave infrared radiation. Why? Because it gets the PET resin to that critical glass transition temperature fast, without scorching the outer wall of the bottle. It’s all in the glass and the fit Blow molding puts a massive amount of thermal shock on a lamp. To handle that, we use high-purity quartz glass. It’s tough. We also obsess over the connectors—usually R7s or Sk15. Here’s the thing: if the fit is loose, you get a hot spot at the terminal. That hot spot will melt your holder and kill the lamp. It’s a avoidable headache. Some of our versions even have a special coating that bounces heat back toward the preform, which just makes the whole process more efficient. Making it work in your shop These are simple drop-in replacements. You won’t need to mess with your wiring or swap out your reflectors. Just pop them in and go. But a word of caution: high-wattage tubes put out a ton of ambient heat. If you’re cranking up the power to speed up your cycles,**make sure your cooling blowers are spotless.**If the airflow is blocked, the lamp temperature spikes and your tungsten filament is toast. One last tip? Don’t replace every lamp at once. Stagger them. It keeps your heat profile consistent across all the zones and saves you from a sudden, total oven overhaul.
