On a SIPA SFL 2/2 stretch blow molding line, you don’t set preform heating and walk away. It’s the first variable that turns into scrap the moment it drifts. When the heating tunnel lamps start underperforming, you know it fast—uneven wall distribution, blown bottles, then the domino effect: jams and micro-stoppages that bleed margin. The SIPA SFL 2/2 linear blower lamp is built as a direct-fit replacement, and it does the one job that matters: it keeps the heating profile stable, shift after shift. What matters technically The SFL 2/2 linear blower lamp runs short-wave infrared halogen emitters inside a quartz tube, chosen for quick thermal response and repeatable output. The geometry and mounting match the SFL 2/2 heating tunnel, and the termination is R7s—so you can swap the lamp without rewiring the reflector assembly. We spec tight filament tolerances and a defined spectral output, because that’s what keeps preform surface temperature inside the narrow band the blow molder expects. The result is a heating curve that doesn’t wander from lamp to lamp. Why it works on the SFL 2/2 In stretch blow molding, the preform has to hit the right temperature across the neck, shoulder, and body before high-pressure air stretches it. A lamp that heats fast and holds steady output keeps cycle times consistent and cuts rejects. On the floor, teams running the SFL 2/2 see fewer heating-related line stops and more predictable quality—without changing the lamp footprint or the control interface. Things to know on install Installation is straightforward, but the reflector and airflow path are part of the thermal balance. Match lamp length and wattage exactly, and check reflector condition plus cooling airflow in the tunnel. Misalignment or blocked airflow will create hot spots and shorten lamp life. Ambient dust and oil love to coat quartz. Keep the tunnel clean, or you’ll watch output drop and lamp life collapse faster than you expect.
