Getting the Heat Right for Husky HyPET Systems

If you’ve spent any time with high-speed PET blowing, you know the struggle. You’re pushing for speed, but the heat just won’t get where it needs to go. The surface of the preform gets scorched, but the core stays cold. Then, the moment you blow, you get uneven walls or—even worse—bottles that just burst. It’s frustrating. That’s exactly why we built our infrared bulbs the way we did. We wanted to fix that “cold core” problem for anyone running Husky HyPET setups.

On the blow molding floor, preform heating isn’t some black box. It’s a controlled thermal process, plain and simple. If your IR bulbs don’t pull their weight, you’re staring down uneven wall thickness, flash, and scrap. And if they burn out early, the whole line stops. We build short-wave quartz halogen IR emitters that match the heating tunnel geometry and power profiles on Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB machines. What matters under the hood Our PET blow molding IR bulbs run on standard voltages (120V/230V) and cover the wattages you need for preform heating. They respond fast and hold steady output in the 0.8–1.6 µm band. The filament layout and reflector geometry are aimed at repeatable temperature uniformity across the preform shoulder and body. We spec quartz glass for thermal shock resistance, and standard R7s or custom connectors so they drop in and fit right. You’re looking at 5,000+ hours of stable output, with less than 5% energy drop over the service life. Why this matters on your line In stretch blow molding, the cycle is set by heating, not by the blow station. These IR bulbs cut warm-up time and keep the heating curve consistent, so you run fewer rejects and less recalibration. Energy use comes down because the emitter heats on demand and holds setpoint without overshoot. And with global supply, you keep Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB lines running without getting burned by long lead times. A few shop-floor reminders IR heating is sensitive to spacing and reflector condition. Install with OEM-spec clearance and check reflector alignment — misalignment creates hot spots and chews up lamp life. Match voltage and wattage to the socket, and keep preforms dry. Surface moisture scatters energy and drives unstable heating. If you’re running 24/7, schedule lamp rotation to balance aging across the tunnel.
