Can New IR Lamps Actually Speed Up Your Old Krones Machine?

If you’re running an older blow molding line, you know the feeling. You want more speed, but the machine just feels like it’s hit a wall. It’s easy to assume the hardware is just too old to keep up with today’s cycle times. But here’s the thing: the problem usually isn’t the gears or the timing. It’s the heat. Most of the time, the bottleneck is simply how fast you can get that preform ready. If your IR lamps are worn out, you’re fighting a losing battle. Swapping those old bulbs for high-density halogen elements can actually move the needle on your daily output. Why your old lamps are lying to you Lamps don’t just “work” or “burn out.” They fade. Over time, the tungsten filament gets thin and the quartz glass gets cloudy. You might think they’re still putting out the same heat, but the actual wattage hitting the plastic is dropping. When we match a lamp to Krones specs but bump up the heat density, something cool happens. The preform heats up faster. Because it spends less time in the oven, you can crank up the machine speed without worrying about under-heating the plastic. The nitty-gritty on the gear We use heavy-wall quartz because these things take a beating from the thermal stress. Whether you’re using R7s or Sk15 connectors, the fit has to be perfect. If the connection is loose, you get arcing at high currents, and that’s a headache nobody wants. Plus, some of our tubes have special coatings. Instead of just scorching the outside of the PET, the heat actually sinks deeper into the wall. It’s a much cleaner way to get the plastic pliable. The catch (because there’s always one) A drop-in replacement is fast and easy. But you can’t just ignore the rest of the line. If you push your IR lamps to the limit to get more bottles per minute, your cooling blow-molds have to work a lot harder. Keep an eye on your chiller. If the molds can’t pull the heat out fast enough, your bottles will start to deform. But if you get the wiring right and balance your oven zones? You can often squeeze another 5-10% of production out of a legacy machine. It’s a lot cheaper than buying a whole new line.
