Getting Your Krones Contiform Heating Just Right

If you’re running a Krones Contiform line, you know the struggle. It’s all a balancing act between hitting your power targets and making sure your lamps don’t burn out every five minutes. When those original lamps finally go, you can’t just throw any old tube in there. You need a replacement that matches the original wattage and spectral output. Why? Because if the heat is uneven, your preforms are going to suffer. The Heat Factor We build these lamps for high-voltage, shortwave infrared output specifically for SMF blower ovens. It’s about getting that PET preform to its glass transition temperature fast. Here’s the thing: if you go too low on the wattage, you’ll end up with cold spots and bottles that burst. But if you push it too hard? You risk scorching the plastic. It’s a tight window. The Build We use heavy-wall quartz glass because these things take a beating from rapid thermal cycling. Most of our units use R7s or Sk15 connectors. These aren’t just about fitting into the slot. They’re designed to keep a rock-solid electrical contact. In a high-current environment, a loose connection is a nightmare—it leads to terminal melt-downs. For some specific setups, we add a specialized coating to the quartz. This tweaks the infrared wavelength so the heat actually sinks into the PET instead of just bouncing off and warming up your oven walls. Swapping Them Out The good news is that these are direct replacements. You just swap them in. No messing with the wiring or tweaking the reflectors. Simple. But a word of advice: if you run these lamps at max power, your cooling system has to work harder. If your ventilation is clogged or your blowers are on their last legs, the lamps will run too hot and die way sooner than they should. While you’re in there changing the lamps, do yourself a favor and wipe down your reflectors. It keeps the heat where it belongs and saves you a headache later.

Out on the blow molding floor, an SMF blower heating tunnel doesn’t care what parts are on the way. The second a lamp starts to dim or a zone drifts, preform heating falls off spec—and you’re suddenly chasing rejects. We built our replacement lamp for SMF blowers to get you back to heating that’s stable and repeatable, quickly. What matters under the hood This is a short-wave infrared emitter, specced to match the thermal profile and electrical constraints of SMF-style heating modules. Quartz envelope, filament layout—everything is chosen so the preform neck and body ramp fast and stay under tight control. Wattage, voltage, and base are matched to the original: common variants are 1500W and 2000W at 230V with R7s connectors, and the lengths line up with standard tunnel banks. The payoff is predictable heat density cycle after cycle, so you’re not fighting uneven wall thickness or crystallization. Why it fits in the real world Compatibility isn’t a slogan here—it’s a drawing and a test. We engineered the lamp to drop straight into SMF-based blow molders across the major platforms, including Sidel Matrix, Krones Contiform, and Husky HyPET systems. It’s a 1:1 fit on OEM envelope dimensions, mounting, and wiring. What that translates to on the line: fewer changeover hours, less scrap from temperature swings, and stretch behavior that stays consistent in PET bottles. We’ve seen units run 5,000+ hours with less than 5% output drop, keeping the heating curve flat when the schedule is tight. The install details that keep it honest Installation is straightforward, but alignment is where people get tripped up. Check the lamp position in the reflector, and take a hard look at reflector condition—pitting or oxidation changes the spot profile and can create hot spots. Confirm voltage at the terminal, and use the right ceramic holder and lead wire rated for the temperature and vibration inside the tunnel. After replacement, give it a proper warm-up window. Let the zone PID settle before you call it good—or bad. If the machine runs in a high-humidity washdown area, protect the connections and pick the appropriate IP-rated hardware. That’s how you keep downtime off the board.
