Preform heating uniformity issues

Fri, 26 Jun 2026 08:03:56 +0800

On the blow molding line, uneven preform heating quietly chews through margins. You see it in off-spec bottles, in the scrap pile, and in the sudden stops when the heating tunnel trips. Every minute of unplanned downtime costs. Every kilowatt wasted adds up. The root cause is straightforward: if the infrared profile isn’t stable across every preform, stretch blow molding can’t deliver consistent wall thickness or strength.

What matters under the hood

We build the heating system around repeatable, measurable performance. Short-wave quartz infrared emitters give you rapid response and tight spectral control, so the energy lands exactly where the preform needs it. Each emitter is matched to OEM voltage and wattage specs, with R7s connectors and standardized mounting for Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB blow molders. Reflector geometry and zone control keep the heating tunnel’s temperature spread within ±2°C across the preform array. The payoff is uniform heating from neck to base, faster recovery after jams, and fewer thermal overshoots.
