On the plant floor, a Sidel SBO 4/6 blow molder doesn’t have time to wait for a tired lamp to drift out of tolerance. Once preform heating starts to wander, you’re suddenly chasing thin walls, haze, and short shots. We built our replacement IR lamp for the Sidel SBO 4/6 to keep the heating tunnel honest—shift after shift. What matters, technically We hit the OEM specs exactly: 1200 W, 230 V, short-wave halogen, quartz envelope, and R7s connector. The filament layout and focal distance are matched to the SBO reflector geometry, so the preform neck stays cool while the body gets even energy. Peak wavelength is 950–1050 nm, response is fast, and filament position is held to a tight tolerance. The payoff: repeatable crystallinity, predictable stretch, and cycle times that stay stable. Why it holds up on the line Because the parameters line up 1:1 with Sidel, and the same thermal envelope approach fits Krones, SIPA, Husky, SACMI, and Nissei ASB machines, you drop the lamp in and run. No retuning the heating profile. Warm-up is quicker, output stays steady for 5,000+ hours, and lamp-related rejects drop. Energy stays close to baseline, and lamp changes come less often—less downtime, fewer spares on the shelf. A few shop-floor reminders Match the lamp to the reflector condition—pitting or oxidation will move the hot spot and give you hot/cold bands. Before installation, confirm voltage and socket alignment, and keep skin off the quartz. If you’re switching from older lamps, expect a small ramp; set the PID once, then lock the profile. This is a direct-spec replacement—plug-and-run on the SBO 4/6, with no machine re-certification.
