Out on the blow molding floor, uneven preform heating isn’t just a speed killer—it’s a scrap generator. When the heating tunnel can’t hold setpoint consistently across the row, you end up with skewed bottles, blown gates, and walls that are all over the map. We supply PET blowing IR lamps that are built to match OEM heating performance, not just drop into a socket.
What matters, technically
We engineer our infrared emitters around the real PET stretch blow molding heating profile: rapid, focused energy with stable spectral output. You can spec short-wave quartz or halogen, sized to fit common blow molder heating stations—rated 1.5 kW to 3.0 kW, 100–240 V, with R7s connectors and standard mounting footprints. They come up to temperature fast after a changeover, and the filament geometry is tight enough to improve uniformity across the preform shoulder and body.
Why this works on your machines
Whether you’re running Sidel, Krones, SIPA, Husky, SACMI, or Nissei ASB, repeatable preform heating is what keeps cycle time, fill integrity, and bottle weight in line. Our lamps meet OEM electrical and dimensional constraints, so you can swap them in without re-engineering the reflector path or rewiring the station. In practice, that means fewer temperature excursions, less scrap from off-spec bottles, and fewer unplanned stops chasing heating drift. Energy use stays predictable because output holds steady over the life of the lamp.
The details that keep it honest
Matching wattage, voltage, and base type is only half the job. Reflector condition, alignment, and clean glass are what keep the heat on the preform instead of wasting it on the tunnel sheet. Install with the correct torque, verify focal position, and keep the emitter face free of film build. If your line runs long cycles or sees high ambient heat, plan replacements around scheduled maintenance—high-output IR lamps still age, and swapping them proactively beats paying for a line stop.
