Fixing Those Annoying Heat Gaps in KHS Blow Molding Lines

Ever deal with PET bottles that come out looking “pearly” or have walls that are thin in some spots and thick in others? It’s a headache. Usually, it comes down to uneven heating in your KHS machines. You get these hot spots that basically chew through the preform, leaving you with a bottle that isn’t strong enough to do its job. We make IR lamps that slide right into your KHS systems to kill those gaps in heat distribution. The secret is in the build. Most standard IR lamps have “cold ends”—spots where the heat just drops off. We fixed that. By tweaking how the tungsten filament is wound and using really pure quartz, we make sure the energy is steady from one end of the tube to the other. It takes the guesswork out of your oven settings. If you’re running a high-speed line, these lamps just hold their ground, even when you’re cycling fast. Will they actually fit? Yes. They match the KHS footprint exactly. We use high-purity quartz so the glass doesn’t cloud up and fade over time. Even the connectors are beefed up. We know these get handled a lot during replacements, so we built them to stay tight. No arcing, no overheating—just a solid connection. One quick tip: keep an eye on your airflow. If you push more power into a shorter tube, you’re increasing the heat density. That’s great for the bottle, but it puts more pressure on your cooling blowers. Just make sure your cooling system can handle the extra load so you don’t bake your oven chassis. What this looks like on the floor When you swap out the OEM lamps for these, you’ll notice the temperature is way more consistent across the preform. The plastic stretches evenly. That means fewer bottles hitting the scrap bin and way less time spent fiddling with oven knobs trying to get the settings “just right.” Plus, we built these to tank the voltage spikes you get in a loud industrial plant. They won’t just pop the second the power fluctuates.

Stop Buying New Blow Molders. Just Fix the Heat.

If you’re running a mid-sized PET shop, you probably have a few old blow molding machines that have seen better days. They still work, but the heating is… temperamental. You get inconsistent preforms, and it slows everything down. Here is the secret: You don’t actually need to drop a fortune on a brand-new machine. Most of the time, you just need better heat. By swapping out those standard heating elements for high-density IR modules, you can speed up your cycles and push out way more bottles without the massive capital expense. The trick is all in the density. Think of it this way. If we pack more wattage into a shorter space, we’re concentrating the heat. This hits the PET preform harder and faster, getting it to that “sweet spot” temperature much quicker than a standard lamp would. And if we bump up the voltage? That’s a win for your electrical setup. It lowers the current draw, which means you don’t have to worry about voltage drops if your machine is sitting at the far end of a long cable run. Why quartz matters. We use halogen-filled quartz tubes because they shift the heat toward the short-wave spectrum. Why does that matter? Because short-wave IR actually sinks into the PET wall rather than just bouncing off the surface. It’s a deeper, more efficient soak. We usually stick with R7s or Sk15 connectors. They’re simple, they fit right in, and they keep the electrical contact tight. No loose fits, no sparking, and—most importantly—no charred sockets when things get hot. The “Catch” (And how to handle it). Installing these is pretty easy. You wire them into your current controllers and tweak your PID settings to handle the faster ramp-up. But, you have to be careful. When you crank up the heat density, the window for error gets smaller. If your conveyor speed is still set for the old, slower lamps, you’re going to burn your preforms or end up with that annoying pearlescence. You’ll need to sync your oven timing with the new wattage. Also, make sure your cooling molds can keep up. You’re feeding them hotter preforms now, so they need to be able to pull that heat away quickly to keep your bottles stable. It’s a bit of a balancing act, but once you nail the timing? It’s a completely different machine.

Getting the Heat Right in Your Husky HyPET System

If you’ve spent any time around high-speed PET blow molding, you know the struggle. It’s not about how much power you can throw at the preform; it’s about where that heat actually goes. The nightmare is scorching the outside of the plastic while the inside stays cold. We’ve spent a lot of time figuring out how to stop that. Our IR lamps are built to sink heat deep into the wall of the preform, so the core hits the right temperature before the surface starts to degrade. The trick to deep penetration We stick with short-wave and medium-wave emitters because they actually get inside the plastic. By tweaking the filament and using really pure quartz, we stop the energy from just bouncing off the surface. This is a huge deal if you’re running heavy-wall containers or pushing your cycles so fast that the preforms barely have time to breathe in the oven. It just works. Fitting them in These are drop-in replacements. They fit the Husky specs perfectly, so you aren’t messing around with modifications. We use high-purity quartz glass because nobody wants their lamps clouding up after a few weeks. Plus, the shape matches the HyPET oven footprint exactly. No more annoying cold spots. One heads-up, though: if you’re cranking the heat to the max, keep an eye on your cooling fans. If your cooling can’t keep up with the extra throughput, you might actually warp your reflector shields. It’s a pain to fix, so just double-check your airflow. Keeping things running High-speed modulation is brutal on equipment. All those aggressive voltage swings usually kill filaments. To stop that, we reinforced the electrodes. The result? A steady thermal output and bottle walls that actually stay consistent. A pro tip from experience: keep a strict cleaning schedule for those quartz envelopes. If they get dirty, you get hotspots, and hotspots lead to broken tubes. And for heaven’s sake, make sure they’re aligned. If the radiation isn’t hitting the center of the preform, you’re just wasting energy.

Stop the Constant Tube Burn-outs on Your SIG Blomax Line

If you’re tired of your SIG Blomax tubes popping left and right, you’ve probably spent some time blaming the power supply. But here’s the thing: it’s usually not the electricity. It’s the physical stress. High-speed PET blowing is brutal. Between the constant vibration and the wild swings in temperature, standard IR lamps just can’t keep up. They wear out. They snap. They fail. We got tired of seeing that happen, so we redesigned our replacement lamps to be a lot tougher.

Making Your PET Oven Lamps Actually Work (Without the Headache)

Every PET blowing machine is a little different. Different brands, different heating profiles—it’s a bit of a mess. But at the end of the day, the physics of heating a preform doesn’t change. We wanted to fix the frustration of hunting for the “perfect” lamp, so we built ours to just work. Whether you’re running a machine from a decade ago or something brand new, our lamps fit into about 95% of the equipment out there. We just keep it simple and focus on the three things that actually matter: the power, the heat, and the size. The Power Struggle Here is where most people run into trouble. You can’t just throw any lamp into any socket. If you put a 230V lamp into a circuit meant for 400V, you’re never going to hit your target temperature. It’s that simple. We make tubes for pretty much every industrial voltage. This ensures the heat density is exactly what your oven was designed for. If you need fast cycle times, you need high-wattage tubes to move that thermal energy quickly. But a quick heads-up: those high-density lamps put a lot of pressure on your reflectors. If your reflectors are dirty or pitted, the heat bounces right back into the tube. That’s a shortcut to a dead lamp. Keep them clean. The Build We use heavy-wall quartz glass because these things take a beating. The rapid heating and cooling—the “thermal shock”—would crack cheaper glass. Inside, we use halogen gas. It lets the filament get hotter without burning out the wire, which means you get more IR punch per millimeter of tube. As for the plugs? We stick to the basics: R7s and SK15. You can just pop them in. No rewiring, no modifying sockets, no swearing at the machine for two hours. Getting the Heat Right The real goal is avoiding those annoying “cold spots.” You know the ones—they lead to uneven walls or, even worse, bottles that burst during the blow stage. Our lamps use shortwave IR to punch through the PET wall fast. And because we’re obsessive about the length and diameter, they slide right into your existing racks. No custom brackets, no “making it fit.” Just a direct fit that keeps the lamp at the exact distance it needs to be from the preform. It just works.

Krones Pet Aseptic blower heating tube

On a Krones aseptic PET line, the heating tunnel is where the day’s schedule gets made or lost. Preforms have to come up to temperature fast and even, or you’re instantly chasing thin walls, uneven stretch, and fill problems that shut the line down. When the heating tube can’t deliver, you see it in scrap, in power draw, and in the overtime it takes to keep the blow molder honest. We built the Krones Pet Aseptic blower heating tube as a direct-fit, engineered replacement for Krones aseptic blow molding machines. It’s an infrared emitter designed to match the original OEM thermal profile, mechanical footprint, and electrical interface—so the heating zone behaves the way the machine was intended to run.
