On the blow molding floor, baby bottle preforms don’t leave you any wiggle room. PC needs heat that’s tight and repeatable—too cold and you’ll crack in the stretch; too hot and you’ll kill the clarity with haze. When the OEM lamp finally burns out, you need a replacement that hits the same thermal profile, right away. What matters under the hood We build the PC baby bottle preform heating lamp as a straight 1:1 match to the heating emitters used on Sidel, Krones, SIPA, Husky, and the major SBM lines. It’s a short-wave infrared halogen emitter: 230V with a 200–240V tolerance, 1.2 kW draw, and it drops into standard R7s connectors and quartz sleeve dimensions. The filament geometry and reflector layout copy the OEM beam pattern, so the heating tunnel lays down the same power density across the preform shoulder and body. You get 2–3 seconds to setpoint, and the lamp holds output within 5% after 5,000+ hours—stable enough to keep stretch ratios where they need to be. Why it holds up on a fast SBM line You’re running at pace—typical SBM cycles for baby bottles squeeze the heating window hard. This lamp keeps preform surface temperature even, which cuts down pinholes and stress whitening, and keeps wall thickness consistent. You’ll also see energy use drop, because the emitted energy gets absorbed by the PC, not by the air and conveyor hardware. And when you swap in a true 1:1 match, you skip the headache of retuning the whole heating zone. The practical bits Installation is straightforward: seat the R7s correctly, mind the orientation, and verify voltage. Keep the quartz sleeve clean—too much dust or coolant mist will skew absorption and invite hot spots. And remember, PC is sensitive to overheating at the neck finish, so make sure your existing shielding and dwell timing stay unchanged. If your line has older reflectors or a modified tunnel, run a quick thermal scan after the first changeover to confirm uniformity.
