On a PET line, the heating tunnel is where you earn your stability. Preforms arrive with tight tolerances, and the blow molder needs wall temperature that’s consistent before stretch. If the IR output drifts or lamp-to-preform distance is even slightly off, you’ll see uneven stretch, weak necks, or crystallization. Then the downtime starts. We built a custom IR module to drop in as a direct replacement for the OEM heating—1:1 geometry and electrical fit—so you can swap it in without re-engineering the tunnel. What actually matters is matching the energy profile to the preform. Our module runs short-wave infrared with quartz emitters, tuned to PET absorption peaks so heat penetrates fast without scorching the surface. Power is sized to your blow molder’s cycle—Sidel, Krones, SIPA, Husky, SACMI, or Nissei ASB—and we match the original voltage, connector type (typically R7s), and mounting. The payoff is repeatable heating with tighter band control, so stretch ratios stay stable and rejects drop. Here’s why it works: it puts the machine back inside its designed heating window. You keep the same preform path, the same dwell, and the same timing, but you remove variability from lamp aging and drift. You get faster warm-ups, fewer lamp changes, and lower kWh per thousand bottles. In practice, that means more uptime and less scrap. One thing to get right: customization needs the right interface data. Send us the OEM lamp specs, the heating zone layout, and the preform geometry. The module will fit, but you still have to verify clearances and reflector alignment in your tunnel—misalignment moves the hot spot and wipes out the gains.
