On a rotary blow molding line, heating drift will throw your whole cycle off. Preforms come out uneven, scrap climbs, and you end up chasing temperature bands instead of running parts. The SMI rotary blow molder lamp was built to give you back the heating profile the machine was designed to run. What matters, technically We build this as a direct-fit infrared emitter for SMI rotary blow molders, with 1:1 parameter matching to OEM performance. Typical units run 1200–1500 W, 220–240 V, and the quartz tube is engineered for stable short-wave output so preform heating is fast and repeatable. Dimensions and the R7s connector are held to the same tolerances as the original, so it drops straight into the heating tunnel without any modification. We take the same approach on lamps for Sidel, Krones, SIPA, Husky, and Nissei ASB—same power density, same thermal response, same expectations for control. Why this works on a rotary line With rotary stretch blow molding, the heating tunnel sees parts continuously and cycles constantly. Matching wattage and spectral output keeps surface temperature consistent, so stretch ratios hold and bottle quality stabilizes. You see fewer rejects from overheated necks or cool spots on the body, and fewer unplanned stops for lamp swaps. Energy stays in line because the emitter comes up fast and holds the set point without overshoot. A few shop-floor details Installation is straightforward, but the lamp has to sit square in the R7s socket and align to the reflector. Misalignment will give you uneven heating and cut service life. Also, confirm your heating controller’s voltage and timer settings match the lamp rating—running a 240 V emitter on a mismatched control can push output outside the intended profile. Schedule replacements around planned maintenance windows so the heating profile stays consistent.
