On a high-speed blow molding line, preform heating is where everything starts. If the infrared output drifts or the lamp/reflector geometry is off, you’ll see uneven stretch, crystallized shoulders, and a run of rejects that hits the floor fast. And when you’re waiting on a replacement that isn’t a straight drop-in, downtime piles up and the losses compound. What matters under the hood We built this infrared lamp to match what the OEMs call for in the field: 380V, 2000W, stable resistive load, and repeatable radiant output. The quartz envelope and halogen/tungsten filament are tuned for quick response and consistent spectral output in the short-wave band—exactly what most stretch blow molders lean on for clean, fast preform surface heating. Physical dimensions and the R7s connector are held to 1:1 tolerances, so it drops straight into the heating tunnel without messing with clamps, brackets, or wiring looms. Why it holds up on real lines This unit is engineered as a direct-spec swap for the mainstream blow molders—Sidel, Krones, SIPA, Husky, and other machines running similar heating modules. Keep the same voltage and wattage, and you keep the thermal profile your process was validated around. Cycle times don’t slip, and bottle quality stays tight. In practice, that means fewer setpoint hunts, less scrap from hot/cold bands, and repeatable performance from lamp to lamp. Energy draw stays where it should, and because the form factor matches the reflector geometry, you maintain the intended heat distribution across the preform wall. What to watch for Installation is plug-and-play when you match the lamp to the exact machine model and heating section. That said, reflector condition matters. If the reflector is pitted or oxidized, spot size and temperature uniformity change—pair a new lamp with a clean reflector for the best result. Also confirm the local mains supply is 380V. Voltage imbalance or under-spec cabling can shorten lamp life. Expect typical service life in the 5,000–8,000 hour window depending on line speed and on/off cycles, and schedule spares around your preventive maintenance windows.
