Making PET Heating Lamps That Actually Fit Your Machine

We’ve all been there. You buy a replacement part, and it almost fits. But “almost” doesn’t cut it when your production line is down. That’s why we built our infrared lamps to be simple drop-in replacements for about 95% of the PET blowing machines out there. We didn’t just make a generic lamp. We looked at all the different brands and figured out how to standardize the bits that actually matter—the plugs and the power—so you don’t have to mess around with your machine’s wiring. Let’s talk power. Most PET lines use high-voltage arrays to keep the heat consistent across those long oven banks. We make our tubes in 230V and 400V versions. Here is the trick: the 400V tube lets you crank up the wattage without drawing so much current that you risk melting your wires. It gives you the heat you need for fast cycles. Just a heads-up: if you’re running a 2500W tube, make sure your cooling fans are actually doing their job. If the oven gets too hot, the ends of the lamps will burn out way too fast. The build quality. We use heavy-wall quartz glass. Why? Because cheap glass bows when it gets hot, and that’s a recipe for disaster. We also use halogen-cycled tungsten filaments, which let the lamps run hotter than your standard IR bulb. As for the connections, we stick to R7s and Sk15 bases. They’re the industry standards for a reason. Since the footprints match exactly, you can just swap out a dead lamp and get back to work. No modifying sockets, no hacking the frame. Just plug and play. Getting the heat right. The goal is simple: soften the preform quickly, but don’t scorch the plastic. Our short-wave radiation sinks into the PET wall fast. We even offer coated versions to tweak the emission spectrum. This is a huge plus because it stops heat from wasting away into the oven walls and pushes it straight into the preform. It speeds everything up. You can push your machine faster and still get a bottle with perfectly even walls. No thin spots, no failures. Just a better bottle, faster.

Can a few new lamps actually save your old blow-molding machine?

Let’s be honest: most small PET shops are running machines that have seen better days. They’re reliable, but they’re slow. When you’re trying to hit modern cycle times with an old rig, it feels like you’re fighting a losing battle. You might think the only way out is to drop a fortune on a brand-new machine. But before you do that, take a look at your heating oven. That’s usually where the real bottleneck is hiding. Often, just swapping out those tired, old infrared lamps for high-density halogen tubes is enough to wake the whole machine up.

Stop Overpaying for Your Krones Contiform IR Lamps

Let’s be honest: OEM parts are expensive. When you’re running Krones Contiform machines, those infrared lamps are essential, but the price tag on the brand-name replacements can really chew through your margins. You need the heat to be perfect, but you don’t need to pay a “brand tax” just to keep your line moving.

The trick to getting the heat right

Heating PET preforms is a bit of a balancing act. If the heat isn’t hitting the exact right spots, you’re in trouble. You end up with “cold spots,” which means your bottles come out with uneven walls or that annoying pearlescent look. Not a good look for the final product. We built our lamps to hit those same specific absorption bands that PET requires. The goal is simple: uniform heat from top to bottom. No guesswork, just a consistent glow that gets the plastic to the right temperature every single time.

Stop Replacing Your Machines. Just Fix the Heat.

If you’re running a mid-sized PET shop, you probably have a few older blow-molding machines that just can’t keep up anymore. They’re reliable, but they’re slow. Usually, the problem isn’t the machine itself—it’s the oven. Buying a brand new line is a nightmare for your budget. But there’s a shortcut. Instead of scrapping the whole thing, you can just swap out those tired old infrared lamps for high-density IR modules. It’s a way to squeeze more speed out of the gear you already own. The secret is all in the heat density. To get more bottles per minute, you have to get the PET preform to the right temperature, and you have to do it fast. We build our modules with specific voltage and wattage to push more energy into the plastic. Think of it as a faster ramp-up. You get more heat hitting the material in less time, which means you can crank up the BPM without worrying about the base of the bottle staying too cold. The nitty-gritty stuff (Quartz and Coatings) We don’t use flimsy materials here. We use heavy-wall quartz glass so the tubes don’t just pop under high thermal stress. But the real trick is the coating. Depending on how thick your preforms are, we apply a specific layer to the quartz. This makes sure the heat actually sinks into the plastic instead of just bouncing off the surface. And don’t worry about a massive electrical overhaul. We use standard R7s or Sk15 connectors. You just plug them in. It’s a simple drop-in replacement. One thing to watch out for… Here’s the catch: more heat means you need more air. If you put in a high-wattage module to shave a few seconds off your cycle, your cooling fans have to be able to handle it. If your airflow is weak, you’ll start seeing scorched preforms or annoying “hot spots.” It’s a balancing act. You have to match the IR output with how much air your machine can actually move. Get that balance right, and you’ll be amazed at how much your old equipment can actually do.
