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.
