On the line, the heating tunnel is where the pressure cooks. preforms roll through, and if the IR profile wanders even a hair, you see it on the blown bottles—thin spots, wall thickness that drifts, necks that crystallize and get flagged in QC. Then you get the added hit of downtime when you have to swap lamps. We built a halogen IR radiator specifically for PETC preforms to keep heating stable and keep your cycle time where it needs to be.
What matters under the hood
We supply a direct-fit halogen infrared emitter, dimensioned and thermally matched to OEM spec. The quartz tube length, arc length, and end-fitting geometry line up with Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB blow molders. You get 230V (with 115V variants), power in the 1,500–2,500 W range, and standard R7s connectors. The peak wavelength is tuned to the PETC absorption band, so you heat the surface fast and even without scorching. The filament layout and reflector geometry are matched to the tunnel envelope, so the energy profile hits the preform uniformly.
Why this plays on the floor
Because it’s a 1:1 parameter match, you can swap lamps without re-tuning the whole heating zone. Operators get repeatable temperature recovery, which keeps stretch consistent and scrap down. Energy use drops, too—the emitter responds quickly and heats on demand. Service life holds at 5,000+ hours with minimal output decay. Fewer changeouts. Less maintenance labor. More uptime on the blow molder.
What to watch for
Installation is plug-and-play on compatible machines, but you still need to confirm the voltage tap, connector type, and tunnel clearance for your specific model. These emitters run hot, so airflow and reflector cleanliness matter. Keep the reflector free of dust, and check the mounting clips every time you replace a lamp to avoid hot spots. If you’re running color-heavy or barrier-layer preforms, confirm the spectral output against your resin blend—additives can shift absorption.
