Getting Your Krones Contiform Heat Just Right

If you’ve spent any time around a Krones Contiform, you know that keeping a steady heat profile is basically a constant battle against heat loss. You’re using shortwave infrared lamps to get those preforms soft enough to blow, but you have to do it without melting the necks. It’s a delicate balance. And let’s be honest—OEM prices can be a nightmare. When the costs spike, you need a replacement that actually works without causing a headache on the line. The deal with power and wattage Here’s the thing: wattage isn’t just a number on a box. If you throw in a lamp with the wrong specs, you’ll start seeing “pearling” or weird, uneven walls in your bottles. Not great. We make sure our lamps match the voltage and wattage of your Contiform oven exactly. We use high-wattage quartz tubes that punch through the PET wall quickly. We also obsess over the resistance values. Why? Because we don’t want your power controllers tripping or trying to overcompensate halfway through a shift. The fit and the glass We use heavy-wall quartz glass because these things take a beating. Rapid cycling creates intense thermal stress, and cheap glass just won’t hold up. Then there’s the connectors—usually R7s or SK15. We machine these to be tight. If a lamp is loose in the socket, it arcs. Once it starts arcing, it burns the socket out, and now you’ve got a much bigger problem than just a dead bulb. Plus, we apply specific coatings to the quartz. This shifts the infrared spectrum so the PET absorbs the heat better. It means more energy goes into the plastic and less of it just wastes away heating up the oven walls. Getting them on the floor Swapping these out is easy. You pull the old tube, wire in the new one, and you’re back in business. But a quick word of advice: check your cooling blowers first. These high-density lamps put a lot of pressure on your ventilation. If your blowers are clogged with dust, the lamp is going to “heat soak” and burn out way too fast. Give your airflow a once-over before you start swapping. It’ll save you a lot of frustration down the road.

Getting Your Sidel PET Blow Molders Back Up to Speed

When you’re looking for replacement lamps for a Sidel blower, you can’t just eyeball the length and hope for the best. It’s more complicated than that. We build our infrared lamps to fit the whole Sidel family—everything from those old-school SBO units to the newer Matrix series. The whole point is that they should just work. You slide them in, turn them on, and get back to production without having to mess with the oven housing or rewire your control boards. The heat side of things Every PET preform is different. If you get the heat density wrong, you end up with a bottle that’s too soft in the base or hasn’t softened enough in the walls. That’s why we match the voltage and wattage to the original specs. If you’re running a high-speed Matrix line, you need heat that hits hard and stays there. We use high-purity quartz glass because it lets the IR radiation get deep into the plastic without leaving those annoying hot spots. The “will it actually fit?” part Most installation nightmares happen at the connectors. There’s nothing worse than a lamp that almost fits, but not quite. We obsess over the end-cap tolerances so they seat perfectly in the sockets. Whether you’re dealing with R7s or those specific Sidel mounts, the footprint is exactly what you’d expect from the OEM part. Why does that matter? Because blow molders vibrate. A lot. If the lamp shifts even a little, your heating becomes uneven and your bottles come out distorted. A quick heads-up on airflow Here’s the thing about high-wattage shortwave lamps: they’re fast. Great for high output, but they put a lot of stress on your oven’s ventilation. If your cooling fans are clogged with dust or just plain dying, these lamps will basically bake your reflectors. That ruins the quartz tube way faster than it should. Whenever you swap out a full bank of lamps, do yourself a favor and check the airflow. Keeping things cool is the only way to make sure your new lamps actually last.

NIR heating lamp for blow molding

Out on the line, a blown PET bottle gets flagged as reject, and the root cause is simple: the preform never got the right temperature profile. The heating tunnel is on, but the energy just isn’t hitting the material where it needs to. That kind of waste is predictable—until you match the emitter to the machine. What matters technically We build NIR infrared lamps for blow molding with tight spectral control, because you need rapid, deep preform heating without scorching the surface. The output is engineered for consistent short-wave response, so the heating zone settles quickly after a changeover. Each lamp is specified by wattage, voltage, overall length, and connector type, and we offer options with R7s ends and custom terminals to match OEM geometry and mounting. The quartz envelope is chosen for thermal shock resistance in reciprocating tunnels, and the filament geometry is tuned to deliver even radiant density across the preform neck and body. Why it works on the machines you run The point is to drop these lamps into existing blow molders without rewiring the heating section. They’re compatible with major platforms—Sidel Matrix, Krones Contiform, Husky HyPET—plus SACMI, SIPA, and Nissei ASB lines. You keep the same lamp footprint, the same mounting points, and the same control logic. The payoff shows up where it counts: faster thermal recovery after startup, tighter temperature uniformity across the preform wall, and fewer rejects from under-heated or over-heated zones. Energy use drops because the emitter heats on demand and responds immediately, and lamp life is extended by design, which trims planned maintenance windows. Here are the practical details Installation is straightforward, but the heating tunnel is a harsh environment. Keep reflectors clean and aligned—even a small shadow can create a hot/cold band on the preform. Verify voltage at the socket; line sag will shorten lamp life. Expect a warm-up period before the profile fully settles, and make sure your PLC temperature feedback matches the new emitter’s response curve. If you run multiple machine models, order by exact machine, heating zone, and OEM lamp number to avoid length or terminal mismatch.

Electric Blow Heater: The Real Deal for PET Blowing

We built this electric blow heater for one simple reason: to put powerful, controllable heat exactly where you need it—right where the air hits the preform. If you’re running PET blowing, you know the drill. You need heat that settles in fast, stays put, and connects clean.

Power, Voltage, and Size—Without the Fluff

This heater runs at 400V and 2500W, packing serious heat into a small space. The 300mm tube length focuses all that energy into one tight zone, so you get a quick warm-up and temperature control you can count on, cycle after cycle. High wattage in a short package is exactly what the air stream demands. But here’s the thing—it also means the parts around it will feel the heat. So plan your airflow and mounting with that in mind.
