On the blow molding floor, uneven preform heating doesn’t just throttle line speed. It shows up as wall thickness that’s all over the map, crystallized shoulders, and scrap that should have been good bottles. When the heating tunnel runs hot in one spot and cold in another, you end up chasing setpoints instead of running a stable process. What matters, technically We spec the 400V 2500W infrared bulb as a direct, spec-matched emitter for blow molders. The quartz envelope gives you fast, clean short-wave output, so preforms heat quickly without the surroundings running hot. At 2500W, you’ve got the power density to hit the target temperature in the preform heating tunnel, even when cycles are stacked high. And the 400V rating lines up with the way most plants are wired, so you can swap it in without rewiring panels or re-rating feeders. Why it works in stretch blow molding In stretch blow molding, a repeatable heat profile is the difference between a line that settles in and one you’re constantly tweaking. This bulb puts you back on the OEM heating curve, so wall distribution stays consistent and rejects drop. You’ll see faster warm-up after changeovers, and with temperature holding steady across the tunnel, alarms quiet down and off-spec material falls off. Energy use goes down, too, because the heater isn’t spending extra time compensating for weak spots. Here are the practical details Installation is straightforward, but alignment is where you earn it. Check the R7s socket and clean the contacts—bad contact means voltage drop and uneven heating. Then verify reflector alignment; if reflectors are off, hot spots show up and you can split preforms. Make sure your control reads temperature accurately, because an emitter that overshoots will scrap bottles just as fast as one that undershoots. Keep the lens clean, run within rated voltage, and you’ll get long service life with stable output.
