Stop Overpaying for Your Krones Contiform Heating Elements

Let’s be honest: OEM parts are expensive. Especially when you’re dealing with heating elements for a Krones Contiform. It feels like every time a lamp goes out, you’re paying a massive premium just for a brand name on the box. We decided to fix that. We’ve put together a technical alternative that hits all the same specs as the originals, but without that eye-watering markup. These aren’t some cheap, generic bulbs you’d find at a hardware store. They are precision-engineered infrared emitters built to fit your oven’s footprint exactly. Getting the heat right The whole point of the Contiform system is using short-wave infrared to get those PET preforms hot and uniform—and doing it fast. We build our lamps to match the exact voltage and wattage of your specific machine generation. You get the same thermal profile and the high-wattage punch needed to keep your cycle times quick. It just works. But here is a pro tip: keep an eye on your cooling fans. If your ventilation is clogged with dust, you’re going to burn through lamps way faster. It doesn’t matter whose brand you’re using; if the oven can’t breathe, the bulbs will fry. The nitty-gritty on the build We use high-purity quartz glass because it lets the IR radiation through without any fuss. Some of our tubes even have a special coating that pushes the heat inward toward the preform. This means less heat leaking into the chassis and more heat where it actually belongs. Then there are the connectors. That’s where most “alternatives” fail. We use industry-standard R7s or SK15 bases depending on your wiring. They are a total drop-in replacement. No rewiring, no modifying sockets, no headaches. You just swap the old tube for the new one, wire it up, and you’re back in business. What this actually does for your floor The biggest win here is your maintenance budget. You’re spending way less per unit, but your bottle quality stays exactly the same. Because we handle the manufacturing, we can keep the tolerances on the lamp length incredibly tight. They sit snug in the reflector, which stops those annoying “hot spots” from forming. You get a smooth, even heat across the entire preform body every single time.

Getting Your Sidel Matrix Oven Back in Sync

Here is the problem with swapping out heating bulbs in a Sidel Matrix oven: if the new lamps aren’t a perfect match, your temperature curve goes sideways. It sounds like a small detail, but it’s a headache. If the wattage or the spectral output is off by even a hair, you’re stuck. Your preforms either don’t get enough heat—leaving you with weird wall thickness—or they get too hot, and you end up with burnt PET. Not a great look. That’s why we build our infrared lamps to mirror the original OEM specs exactly. It’s more than just wattage. A lot of people think as long as the wattage matches, they’re good to go. But it’s actually a balancing act between voltage, length, and filament density. We make sure our tubes hit those original footprints perfectly. This way, when your PLC sends a signal, the heat hitting the resin is exactly what the factory intended. You don’t have to spend hours reprogramming your oven zones. You just plug them in and get back to work. The gritty details We use high-purity quartz glass and a specific halogen gas fill. Why? Because these things take a beating under high thermal stress, and we want them to last. We also made the connectors a simple drop-in replacement. No messing around with your wiring or sockets. Then there’s the coating. That’s where the real magic happens. By dialing in the emissivity of the bulb, we make sure the infrared radiation sinks into the PET wall at just the right depth. A quick heads-up for the shop floor These lamps are designed for high heat density to keep your cycle times tight. But keep this in mind: running them at full tilt puts a lot of pressure on your cooling fans. If your ventilation is clogged or acting up, your oven temperature will spike, no matter how precise the bulbs are. Keep your airflow clean. It’s the best way to make sure your bulbs don’t burn out before their time.

Leading supplier of PET blow molding IR

On the blow molding floor, an off-spec heating tunnel doesn’t just cost you output. It costs you good parts. Preforms that come out of the oven at 110–120°C underheated stretch unevenly. The ones that get overheated haze up and thin out at the neck. You need an infrared emitter that matches your OEM lamp on temperature profile, power density, and response time—without forcing you to retune the whole oven. What matters, technically We build PET blow molding IR emitters that drop in 1:1 to the big blow molders—Sidel, Krones, SIPA, Husky, SACMI, Nissei ASB. The specs are done to OEM tolerances: 230–240V input; quartz and halogen options; 1.0–3.0 kW per zone; peak wavelengths tuned to 0.78–1.2 µm for fast, through-thickness heating. The physical fit is right, too—R7s and bi-pin connectors, 150–350 mm arc lengths, 10 mm and 13 mm tube diameters—so the lamp seats the same way and lines up with the reflector without shimming. We hold tight tolerances on filament geometry and filament-to-reflector distance so you get the same heat distribution across the preform wall. Here’s the point on your blow molder: repeatability is everything. Our IR lamps settle the heating tunnel down—warm up faster to setpoint, hold temperature within ±2°C, and stay consistent through 24/7 runs. That means fewer rejects from uneven stretch, less energy per cycle, and lamp life you can plan around. We’ve got units running 5,000+ hours with under 5% output drop, which keeps the oven setpoint honest and your cycle times steady. Matching the lamp is only half the job. Reflector cleanliness, terminal temperature, and voltage stability at the socket all move the needle. Expect a bit more inrush current on cold starts—plan for soft-start or PID tuning if your controller is sensitive. And if your machine uses custom window coatings or shielding, check the new lamp’s spectral output against your current preform material and colorant so you don’t overshoot at the neck or shoulder.

Infrared lamp 220V 1500W PET

Out on the blow molding floor, the heating tunnel is the pace car. If the preforms run cold, you’re dealing with uneven stretch, weak necks, and a growing pile of rejects. If the lamps are underperforming, you spend your day chasing setpoints instead of running the job. We built this infrared lamp for PET to break that cycle—starting with a 220V, 1500W rating that fits the power budget of standard blow molding heating zones. What matters is the fit to the machine. The 220V, 1500W draw gives you predictable heat density in the tunnel, and the short-wave infrared profile hits PET fast—warming the preform surface without cooking the core. The quartz envelope responds quickly and holds output steady, and the R7s connector drops right into the common mounting and wiring on blow molders from Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB. The result is stable temperature control that repeats shift after shift. And here is why it holds up in real production: it keeps your process stable. With this lamp, preform heating hits setpoint faster, so the blow station sees more consistent material behavior. That means fewer pinholes, tighter weight control, and less scrap. The 220V supply also keeps installation straightforward—no rewiring, no panel re-rating. Over time, you get fewer lamp changes and fewer micro-stops, and that adds up to more uptime. A practical heads-up: infrared heating is line-of-sight, so lamp alignment and reflector cleanliness directly drive uniformity. Confirm the lamp length and focal distance in your heating zone, and expect a short ramp-up after startup before the tunnel fully settles. If you’re running heavy crystalline PET grades or very dark colors, let us know—those materials change heat absorption, and we’ll adjust the profile to keep quality locked in.
