On the blow molding line, uneven preform heating quietly murders uptime. You feel it in the rejects, in the sluggish cycles, and in lamps that burn out way too early. We built our Made in China IR lamp for preform to match the OEM heating tunnel geometry and power profiles, so your stretch blow molding runs the way it should. What matters, technically This is a short-wave infrared emitter—quartz tube, halogen filament—built for fast response and stable output. Standard ratings are 1200–1500 W, 220 V, with R7s connectors that drop straight into the common heating stations. The filament layout is arranged for even axial temperature distribution, and the envelope is sized to match typical preform neck spacing. We tune emissivity and spectral output to heat PET fast without scorching the surface, so the heating tunnel hits setpoint in seconds, not minutes. Why it holds up on the line The lamp is engineered as a direct fit for blow molding machines—Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB included. You get 1:1 parameter matching to OEM specs, so you can swap a lamp without re-tuning the whole heating profile. In practice, that means quicker warm-ups, tighter temperature control across the preform wall, and fewer line stops for lamp changes. Energy use drops because the emitter delivers heat on demand, and cycle consistency improves because the heating band stays stable over long runs. A few shop-floor notes Installation is straightforward, but alignment is critical. If the lamp axis is off, you’ll get hot spots and thin necks. Run the heating tunnel at the recommended voltage and keep the reflectors clean; otherwise, output drift shows up as drift in bottle weight and wall thickness. These lamps work with most blow molders, but verify connector type, length, and wattage against your machine’s OEM drawings before ordering.
