The heating tunnel is where the whole blow molding cell makes or breaks. When preforms come out under-softened, you’re suddenly chasing parison stretch, neck crystallization, and bottles that just miss spec. And when an emitter dies, the line stops — usually at the worst possible minute. You need a spare that drops in and works, not one that turns into a guessing game. What matters under the hood We build PETC preform softening emitters for the way the heating tunnel actually runs: steady radiant heat, fast response, and output that stays stable over long runs. Match the spectrum to your process — short-wave for quick surface heating, medium-wave when you want deeper, more even softening. Each unit is defined by wattage, voltage, length, and connector type, including common R7s bases. Dimensions and mounting geometry are held to tight tolerances, because repeatable reflector alignment and consistent lamp-to-preform distance are what keep temperature uniform across cavities and prevent hot spots that drive scrap. Why it plays on these machines On Sidel, Krones, SIPA, Husky, SACMI, or Nissei ASB blow molders, the heating section sets the pace. A spec-matched emitter restores the original thermal profile without forcing you to retune the whole tunnel, so you claw back the throughput you lose to warm-up drift and uneven stretch. You also cut unplanned stops — no more waiting on a generic lamp to clear customs or for engineering to rework brackets. And when reflectors are aligned and output is stable, energy use falls, because the system isn’t chasing setpoints by running extra amps. Here are the practical details Installation is straightforward, but it isn’t plug-and-play across every machine variant. Double-check wattage, voltage, length, and terminal orientation against your OEM spec plate and reflector socket. Quartz components need careful handling; even minor surface contamination can shorten life or create hot spots. Plan replacements around scheduled stops, not when you’re already in panic mode.
