Stop Wasting Time Waiting for Your Blow Molders to Warm Up

When you’re running high-speed PET blowing, every millisecond counts. If there’s a lag between loading the preform and the actual molding, you’re losing money. That’s exactly why we built our replacement lamps for Krones S24 and SACMI rotary machines. We wanted to kill that annoying delay you usually get with generic infrared tubes. Here is how we actually did it. It mostly comes down to the relationship between voltage and the mass of the filament. We tuned the wattage and voltage to fit the S24 oven perfectly, which cuts down on “thermal inertia.” In plain English? A lighter filament hits its operating temperature way faster. You spend less time idling the machine during start-up or after a sudden stop. We also used high-purity quartz so the heat goes straight into the preform instead of leaking through the tube walls. It’s all in the details. We added a specialized coating to focus short-wave IR radiation. This pushes the heat directly into the PET material rather than letting it bounce off the oven reflectors. And don’t worry about the install. These are drop-in replacements. Whether you’re using R7s or slide-in connectors, we kept the tolerances tight. Why? Because a loose fit leads to arcing, and that’s the fastest way to burn out your end caps. What this looks like on the floor. If you’re running a SACMI rotary system, these lamps help you keep a much tighter temperature profile. You get a consistent heat distribution, which means you stop seeing those annoying variations in the bottle wall thickness. One quick heads-up, though. If you push these lamps to the absolute limit of their voltage spec to get a faster response, they won’t last as long. It’s a trade-off. Just find that sweet spot between your power settings and your production speed so you aren’t swapping them out every few weeks.
