On the blow molding line, uneven preform heating does more than just slow the machine. It shows up as wall thickness drift, crystallized shoulders, and scrap that should have been good bottles. When your Sidel SBO 6 heating tunnel can’t hold a repeatable temperature, both bottle quality and uptime start sliding. We built the Sidel SBO 6 heating lamp bulb to bring the heating profile back to what the machine was designed to run. What matters technically This is a short-wave infrared quartz emitter, engineered to match the Sidel SBO 6 blow molder’s heating architecture. It runs on the machine’s specified voltage and wattage, delivering fast, focused radiant heat that penetrates the PET preform wall quickly and consistently. The quartz tube holds stable output across repeated thermal cycles, and the R7s connector interface lines up with the OEM socket geometry so the lamp seats square and makes reliable contact. In practice, you can set the heating parameters once and expect repeatable results shift after shift. Why it works on an SBO 6 The SBO 6 depends on tight control of preform temperature before stretch blow molding. Our lamp restores the intended heating curve, which helps you hit target bottle weight, reduce stress marks, and keep cycle times steady. Because the response is fast, the tunnel recovers quickly after jams and restarts, cutting down the time spent chasing temperature drift. Energy use drops, too—the emitter heats on demand and holds output without overshoot. A few practical notes Installation is straightforward, but the heating tunnel is a hot, reflective environment. Check lamp alignment, and make sure the reflectors are clean and undamaged; otherwise you’ll get uneven heating even with a good bulb. Also verify socket condition—corrosion or weak spring tension can cause arcing and shorten lamp life. We match the OEM electrical and dimensional specs, but you get the best performance when the whole heating section is maintained as a system.
