On a blow molding line, the heating tunnel sets the pace—and the profit. If the IR emitter is lagging, preforms come out uneven, cycle times creep up, and you’re bleeding money on scrap and wasted energy. For PET lines running Sidel, Krones, SIPA, Husky, SACMI, or Nissei ASB machines, the fix is pretty straightforward: spec in a purpose-built IR emitter for PETC that matches the OEM heating profile. We built the PETC emitter for PET stretch blow molding, using a short-wave halogen profile that drives fast, controllable heat straight into the preform wall. Every detail is chosen for direct interchangeability: standard R7s connector, lengths from 1200–1500 mm, and voltages to match your blow molder. The quartz envelope runs hot and clean, with filament placement kept tight so absorption stays repeatable across the heating tunnel. In real life, that translates to quicker ramp-up, stable temperature bands, and far fewer hot/cold spots that trigger thin walls or stress whitening. Here’s why it sticks on the line. The emitter is tuned for the PETC preform heating window, so you can run tighter profiles without risking overheat at the neck. Users typically see the heating zone’s kWh drop by 5–8%, and lamp life stretches to 5,000+ hours with less than 5% output drift. Fewer changeovers. Lower spares spend. And you get more consistent bottle weight and clarity. Add in faster stabilization after startup, and you can pick up 2–4 bottles per minute on a lot of lines without touching the blow station. Installation is plug-and-play on compatible blow molders, but double-check your machine’s voltage, wattage, and mounting dimensions before ordering. The output density is optimized for PET; if you’re running other materials, you’ll need to retune the heating curve. Keep reflectors clean and aligned, and set your PID to match the emitter’s response time. Do that, and the tunnel runs the way it was designed—fast, steady, and predictable.
