Getting Your Krones Contiform Oven Just Right

Keeping a Krones Contiform line running smoothly 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 other week. When those original KOSME KSB 4000/6000 lamps finally give out, you can’t just throw any old bulb in there. You need a replacement that hits the same wattage and spectral output. If you don’t, you’ll end up with uneven heating in your preforms, and nobody wants to deal with that. The deal with power and voltage These KSB lamps run on high-voltage shortwave infrared. It’s intense. We build ours to handle the specific voltage swings that come with the Contiform power supply. The goal is to cram a lot of wattage into a small space so the heat hits the PET preform wall fast. But here is the catch: your voltage has to be spot on. If it’s off, you’re looking at two options: your filaments will pop way too early, or the plastic just won’t soften enough to blow properly. Quartz and connectors (the gritty details) We use heavy-wall quartz glass because these lamps go through a lot of thermal shock. They heat up and cool down fast. Plus, we fill them with halogen gas. This stops the tungsten filament from evaporating too quickly, which means your light output stays steady for thousands of hours. Then there are the connectors—usually R7s or Sk15. They need to be tight. If the pins are loose, you get arcing. That creates a heat buildup at the socket that can actually melt your wiring. Not a great look. Making it work for PET blowing At the end of the day, you just want the preform body to be the same temperature all the way around. You need that concentrated IR energy to hit the glass transition temperature of the PET quickly. But remember, these things run hot. Really hot. Check your airflow and keep those cooling fans clean. If your cooling system is clogged with dust, the housing will overheat and you’ll cut the life of your lamp in half. We designed these as direct replacements. You can swap them in, save some money on maintenance, and keep your current thermal settings exactly where they are.
