On the blow molding line, uneven preform heating shows up fast: short shots, blown seams, and a scramble to tune the heating tunnel. When the original lamp dims or fails, you’re not just replacing a part—you’re bleeding uptime, scrap, and operator confidence.
What matters, technically
The SIDEL 2002406262 lamp is a short-wave infrared halogen emitter built for PET stretch blow molding. It’s designed to match the SIDEL blow molder heating zone geometry, so response is quick and output stays repeatable. Typical ratings are 240V and 200–400W, depending on the exact machine configuration, with an R7s base and a quartz envelope that holds up in the heating tunnel. The filament layout and reflector profile shape a tight, controllable heating pattern, so the preform neck and body hit set temperature without overshoot.
Why it works on the floor
That control shows up as fewer temperature swings across the preform wall, which cuts variability in bottle weight and strength. You get more consistent stretch behavior, fewer pinholes, and less stress whitening on sensitive designs. Energy use drops because the lamp hits target output fast and holds it steady, instead of wasting power cycling underperforming emitters. Replacement intervals stretch compared to generic lamps, so maintenance windows shrink. Over a full year, plants see fewer unplanned stops, lower scrap, and a clear reduction in spare inventory and labor hours.
The details that keep you out of trouble
Installation is straightforward, but the lamp has to match the machine exactly—voltage, wattage, and fixture type. Double-check the connector and mounting dimensions, then verify the heating zone controller settings after the swap. Handle with clean gloves, wipe the quartz with alcohol, and torque the lamp holder to spec.Stick to the rated voltage; running it higher shortens life and shifts the spectral output—stay within the OEM envelope.
