Stop Fighting with Your KHS Oven

Ever pull a bottle off the line and see those weird wall thickness variations? Or worse, the whole thing is deformed because the heat just isn’t hitting right? It’s frustrating. Usually, it’s not the machine itself—it’s the lamps. Over time, those infrared lamps degrade, and suddenly your thermal profile is all over the place. We’ve spent a lot of time building replacement lamps that actually fit the original KHS footprint. The goal was simple: get rid of those uneven heat fields so you can stop babysitting your oven. Getting the heat where it needs to be These lamps pack a punch. We use a specific voltage-to-length ratio to make sure the heat is steady from one end of the tube to the other. No “cold spots” at the edges. No guessing games. Just a consistent flow of heat that gets your PET resin to the right temperature every single time. The nitty-gritty stuff We use high-purity quartz glass because, let’s be honest, the rapid heating and cooling in these ovens is brutal. The glass has to take that shock without cracking. The filament is tuned for short-wave infrared. Why? Because it actually sinks into the PET preform instead of just bouncing off the surface. And don’t worry about the install. We use standard R7s or SK15 connectors. You just pop them in. No rewiring, no hacking at the housing, no headache. A quick heads-up Here’s the thing: these lamps put out a lot of energy. That means your ventilation has to be on point. If your cooling fans are choked with dust, these lamps will overheat at the end caps and burn out way faster than they should. Give your fans a cleaning before you swap the bulbs. Also, keep an eye on your voltage. A tiny 5% spike can chew through the life of a lamp. But once you’ve got them dialed in? Those annoying “zebra stripes” in your heating disappear. The whole process just feels smoother.

Aoki blow molding IR radiator lamp bulb

On the blow molder, preform heating isn’t a nice-to-have—it’s the first bottleneck. If the heating tunnel starts drifting even a couple of degrees, you’re staring down uneven wall thickness, blown parisons, and scrap climbing fast. That’s why we built the Aoki IR radiator lamp bulb to keep the tunnel stable, with 1:1 parameter matching to the OEM specs you’re already running. What matters, technically This is a short-wave infrared emitter, designed for fast, controllable heating in PET stretch blow molding. The quartz tube runs 1500W, 230V, with an R7s connector and a standard 330mm arc length—dimensions that match the footprint and mounting of mainstream machines like Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB. Peak wavelength sits around 1.0–1.2μm, so energy gets into the preform wall quickly, heating from the inside out and cutting down on surface scorch. It comes up to target temperature in under 30 seconds, which keeps cycle control tight and setpoints repeatable, shift after shift. Why it holds up on the line You’re running high-output lines, and downtime is measured in bottles lost per minute. A lamp that matches the original geometry, power, and thermal response keeps the heating profile consistent without having to re-tune the whole tunnel. The payoff is fewer thickness swings, fewer pinhole rejects, and predictable energy draw. We’ve seen units run 5,000+ hours with less than 5% output drop, which means fewer lamp changes, fewer maintenance interruptions, and throughput that stays steady. A few shop-floor reminders Installation is straightforward—same connector, same clearance—but do yourself a favor and check the reflector. A tired reflector will drop effective irradiance even with a fresh lamp. And keep the lamp surface clean; a thin film of dust or oil can push operating temperature up and shorten service life. Match the lamp to the machine, then match the optics and cleanliness to the lamp.

Urola blow molding machine heater

On the blow molding line, heating drift is the quiet saboteur. You see it in stretch that’s all over the place, in preforms that feel sticky at the neck or come up thin at the base, and in the extra scrap when the heating tunnel just won’t hold the setpoints. On Urola blow molders, the heater is the make-or-break interface between your recipe and repeatable output. If the emitter output or temperature profile is even slightly off, the machine will run—but it won’t run right. What matters, technically We build the Urola blow molding machine heater as a direct-fit infrared module, engineered to fit the machine’s thermal envelope. It uses short-wave halogen emitters in a quartz envelope, because the response curve lines up with how PET preforms need to be heated: fast rise, fast cutoff, and tight control across the heating tunnel zones. Standard configurations are 240V or 400V, with power matched to the original OEM draw so you don’t have to re-balance the electrical load. Termination is R7s, and the length and mounting geometry are held to the original tolerances so alignment—and reflector focus—stays in spec. Here’s why that spec matching matters in practice. When wattage and geometry are matched, the heating tunnel profile settles down, and preform surface temperature variance drops. That means fewer pinholes, cleaner biaxial stretch, and less scrap. Because the emitter starts and stops quickly, cycle-to-cycle heating repeats without waiting for the tunnel to “catch up,” which keeps bottle weight and wall distribution consistent. Energy use comes down too—short-wave infrared heats the preform directly instead of warming the whole tunnel mass. Installation is straightforward, but alignment is not optional. Check reflector condition and emitter position during replacement; even a small offset shifts the hot spot and can show up as asymmetrical bottles. Infrared output also decays with hours. Plan on replacing around 5,000–6,000 hours of operation, and keep spare mounts and R7s connectors on hand so downtime stays short.
