On the blow molding floor, uneven preform heating doesn’t hide. You see it immediately—flash, weak stretch, bottles that just miss spec. When the heater lamp isn’t pulling its weight, you’re not chasing output. You’re chasing scrap and those maddening micro-stops. With a Sidel SBO Series 2, the price of the heater lamp isn’t just a component line item. It’s the cost of keeping your heating stable, cycle after cycle.
What matters, technically
We build the SBO Series 2 heater lamp as a short-wave infrared emitter, matched to the Sidel heating tunnel geometry. The specs are fixed: rated voltage, precise wattage per zone, standard R7s connector, and envelope dimensions that drop straight into the original lamp holder—no modification needed. The quartz envelope and filament design give you fast thermal response, so the heating curve repeats without drifting. Every lamp gets burn-in and output verification against OEM tolerances.
Why it holds up on an SBO line
An SBO blow molding line lives and dies on repeatable preform heating. With these lamps, you get tighter temperature uniformity across the heating tunnel. That cuts down thickness variation and keeps the stretch blow molding process more stable. The payoff is straightforward: fewer rejects, less rework, and uptime that behaves itself. Energy use stays in line, too, because the emitter heats on demand and cools quickly—no wasted heat sitting in the tunnel.
The practical details
Installation is straightforward, but do it right. The lamp has to be aligned in the reflector and seated fully in the R7s socket. If it isn’t, you’ll get hot spots and you’ll be back in there way too soon. Expect peak surface temperatures—handle it like any hot component on the machine. Before ordering, confirm your SBO Series 2 variant and heating zone layout. Some machines run different wattages by zone, so matching matters.
