Stop Overpaying for Your Krones Contiform Lamps
Let’s be honest: OEM parts for Krones Contiform lines are expensive. Like, really expensive. It feels like every time a lamp goes out, you’re taking a huge bite out of your maintenance budget. We figured there’s a better way. We make drop-in replacement lamps that do the exact same job as the originals—hitting those specific infrared requirements for PET preforms—but without the eye-watering price tag.
Getting the Power Right
These lamps run at high wattages because you need that plastic to soften fast. But here is the thing: if your voltage and wattage don’t line up perfectly with your machine’s power supply, you’re asking for trouble. Usually, that means the lamp burns out way too soon. Or worse, you get uneven heat. When that happens, your bottles end up with weird wall thickness—some spots thin, some spots thick. Not ideal. We calibrate our tubes to keep the infrared output steady. Your plastic hits that “sweet spot” temperature where it’s ready to blow, but it doesn’t scorch.
The Nitty-Gritty: Quartz and Connectors
We use high-purity quartz glass. Why? Because these lamps go through a brutal cycle of heating up and cooling down, and cheap glass just can’t handle that kind of thermal shock. We also use a halogen gas fill to keep the tungsten filament from evaporating too quickly. It simply makes the lamp last longer. As for the fit, we stick to standard R7s or Sk15 connectors. They snap in tight. You don’t want a loose connection here—that creates hotspots that can actually melt your socket. That’s a headache nobody needs.
A Few Pro Tips for the Shop Floor
These are direct replacements. You can swap them in without messing around with your reflector housing. Simple. But a word of caution: high-wattage tubes put out a massive amount of heat. If you’re tempted to crank up the wattage to speed up your cycle times, just make sure your cooling system can keep up. If your fans are clogged with dust or just worn out, your lamp life is going to tank. And please, keep your reflectors clean. A dirty reflector wastes about 20% of your heat. It forces the lamp to work harder and run hotter than it needs to. A quick clean saves you money and stress in the long run.
