On the blow molding floor, uneven preform heating isn’t a theory issue. It shows up as flash, brittle PET, or a line that keeps throttling back to chase rejects. We built our infrared heating elements to cut that variability at the source, so your stretch blow molder can run the cycle it was designed for—steady, repeatable, and without the usual temperature drama. What matters, technically Our quartz infrared emitters put fast, direct radiant heat where it needs to be, with tight spectral control. Energy goes into the preform wall, not into heating the air around it. They’re specced to match common blow molder setups: standard watt densities, 120–240 V options, and R7s connectors that drop straight into the existing lamp sockets. The payoff is repeatable temperature rise, predictable soak, and a heating tunnel you can tune instead of chase. Why it holds up in real production With preform heating, time and temperature trade off—until quality falls apart. These elements help you keep that balance without guesswork. You get quicker warm-up, stable output across shifts, and fewer temperature-related rejects. And because the heat is targeted and the response is immediate, you’ll see energy use drop. If you’re running Sidel, Krones, SIPA, Husky, SACMI, or Nissei ASB, that translates to fewer line interruptions and a more consistent bottle weight profile. The details that bite you if you ignore them Infrared heating is unforgiving when reflectors get dirty or fall out of alignment. Output drifts fast if the lamp, reflector, and preform path aren’t lined up. Plan the install with clean contacts, reflector geometry verified, and a documented setpoint map. Also, don’t assume the lamp length and end-fit will “probably work.” Confirm it against your machine’s holder—tight tolerance matters in a crowded heating tunnel.
