When your blow molder is down because the preforms aren’t hitting stretch temperature, you’re bleeding minutes and money. That’s why we build infrared heating lamps for blow molding machines. The heating tunnel isn’t a place for guesswork—it’s where cycle time, bottle weight, and crystal clarity get made or broken. What matters under the hood These are short-wave infrared emitters, built around a quartz envelope and a halogen filament. They dump rapid, focused energy straight into the preform wall. We match common OEM voltages and power densities, so the heat profile stays consistent without re-tuning the whole line. They use standard R7s connectors and standard mounting dimensions, so they drop right into existing heating stations on Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB blow molders. Fast response and tight thermal control mean less time chasing temperature drift and more time running stable cycles. Why this works in stretch blow molding The preform has to be hot enough to stretch evenly, but not so hot it thins out and loses stiffness. These lamps deliver repeatable heating that holds the preform temperature window steady. That cuts scrap from haze, weak heels, and inconsistent wall thickness. It also helps you recover faster after a jam or changeover, because the heating tunnel snaps back to setpoint quickly. On the floor, that translates to fewer temperature-related stops, more consistent bottle quality, and lower energy use per thousand bottles. What to watch for Infrared lamp performance hinges on reflector alignment and clean, dry mounting surfaces. Misalignment creates hot and cold bands across the preform row. Expect shorter lamp life at very high power settings, or in environments heavy with dust and cooling-water mist. Keep the reflectors clean, and confirm your machine’s voltage and connector type before ordering. We can supply lamps matched to your blow molder model, so the replacement is straightforward and the heating profile stays repeatable.
