On the line, seconds matter. When PC baby bottle preforms come out of the heating tunnel with uneven heat, you’re staring down scrap, rework, and a machine that’s always hunting for stability. A heat profile that drifts or falls short hits the margins fast—especially on small-format runs where consistency isn’t optional. We designed this PC baby bottle preform heating lamp to fix that, because it matches the heating behavior your blow molder is built to expect, cycle after cycle. What it is, technically This is a short-wave infrared emitter, built for the preform heating zone on stretch blow molding machines. It runs on standard 230V, delivers focused power to get PC preforms to the right stretch temperature quickly, and it drops in with an R7s connector using OEM mounting points. The quartz envelope responds fast and holds output steady, and the tight focal pattern puts the energy where it belongs—on the preform wall—so you don’t waste heat that can cook the neck or base. We size wattage and geometry so the heat profile stays repeatable, shift after shift. Why it holds up on real lines You need heat that lands in the same spot every time, so the blow molder can run at speed without chasing tolerances. This lamp restores the original heating balance on blow molders from Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB. In practice, that means fewer rejects from inconsistent wall thickness and more uptime, because the heating zone doesn’t need constant retuning. Energy use drops, too, because the emitter targets the preform directly instead of heating the whole tunnel. Over a full year, many plants cut heating-zone energy by 12–18% and cut lamp changes by roughly 30%—which shows up as fewer spares on the shelf and less maintenance labor. What you need to get right Installation is straightforward, but the heating window is sensitive. Make sure the lamp is aligned to the preform axis and the reflector is clean—even a small offset moves the hot spot and shifts bottle weight. Also confirm your power supply is stable; voltage swing changes output and shortens lamp life. If you’re switching to this lamp on a machine that previously used a different spectrum, plan a short validation run. That’s the cleanest way to lock in timing and temperature setpoints before you commit to full production.
