On the blow molder, uneven preform heating isn’t just a quality headache—it’s a countdown to downtime. When the heating tunnel starts fighting you, you end up with wall thickness that drifts, bottles that blow out, and resin that walks straight into the scrap bin. What you need is an infrared emitter that meets the original spec, drops in without rewiring, and holds steady output shift after shift. What matters under the hood We build this 400V, 2000W infrared lamp as a direct-fit for the heating zones on common blow molding machines. The quartz tube comes up fast and lays down even radiant heat, with wavelength output tuned for PET preform heating. It runs on 400V, pulls 2000W, and uses standard R7s connectors, so you can swap it in without touching the socket or bracket. Filament layout and reflector geometry are matched to the OEM heating profile, so temperature distribution across the tunnel stays repeatable. Why it holds up in stretch blow molding In stretch blow molding, the heating window is tight: you need a quick, controllable rise without scorching the preform. This lamp lands in that window with stable output, so you see fewer rejects and more consistent bottle weight. Because it’s OEM-matched, you skip the trial-and-error tuning and get back to running the job the way it was designed. You get OEM-grade heating performance, priced the way direct manufacturing allows—no brand premium baked in. A few shop-floor details Match the lamp to your machine’s voltage and mounting dimensions. Double-check the R7s connector type and make sure the reflector shape lines up with your heating tunnel. Expect a slightly longer warm-up ramp than a halogen unit; plan your changeover around that. Keep the lamp clean and aligned, and keep an eye on the heating-zone thermocouples so you don’t overshoot.
