On the blow molding floor, the heating tunnel is where the pressure really shows. Preforms have to land in a tight temperature window before they stretch; miss it, and you’re staring at weak bottles, blown parisons, and scrap piling up. Short wave infrared heating lamps hand the control back to you. What matters under the hood Short wave infrared delivers fast, focused energy with a peak around 1.0–1.2 µm, which couples straight into PET. In practice, that means preforms heat on the surface quickly without cooking the core. We match OEM voltage, watt density, and lamp geometry so the emitter drops straight into the existing holders and reflectors. Quartz tubes with R7s ends, rated for 2400–3200 W, fit Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB heating sections. Response is near-instant, and dimming is clean, so you can tune profiles without fighting lag. Here’s the payoff: stability at speed. With short wave IR, you can hold tighter thermal windows, trim cycle time, and cut rejects from under-stretch or crystallization. Energy use drops because the heat lands where it needs to—on the preform—not in the tunnel frame. Relamp intervals stretch, so you spend less time on the line and more time shipping. For PET stretch blow molding, that means consistent bottle weight, better top load, and fewer micro-cracks that show up later on the filler. Installation is straightforward, but alignment is where people get tripped up. Reflectors need to be clean and positioned right to avoid hot spots and uneven heating. Keep the lamp free of contact, and verify airflow and temperature limits for the quartz and socket. If your line switches between clear, green, or other PET colors, adjust power density accordingly; darker preforms absorb more energy. Match the lamp to your machine’s specs, and you get predictable performance without re-engineering the heating tunnel.
