You know the drill. The heating tunnel starts to drift, preforms come out uneven, and you spend the shift chasing temperature bands instead of making good bottles. Then maintenance drops the bad news: the OEM lamp is on backorder, and the price is painful. Every unplanned hour down is money straight out the door. What matters technically We spec a half white quartz heating lamp built for blow molding preform heating. The infrared output matches the fast response and stable spectral profile the heating tunnel expects. The half white spectrum cuts visible glare while still delivering strong absorption through the PET preform wall, so you get repeatable heating without scorching. It’s engineered to fit standard R7s connectors and common voltage platforms, with tight filament positioning to keep the hot zone lined up with the preform path. In practice, that means faster thermal recovery after door cycles and more consistent parison temperature. Why it works on the machines you run On Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB blow molders, the heating section has to keep up with high-cavity output. This lamp drops into existing mounts and wiring with minimal changeover, so you can replace at the component level without re-engineering the tunnel. Expect fewer lamp swaps over a production year, lower energy draw per cycle, and more stable bottle quality—less thickness variation, fewer pinholes, and less stress whitening. Here are the practical details Installation is straightforward, but you need to verify lamp length, base type, and voltage against your specific blow molder model and heating zone layout. The quartz envelope runs hot, so keep reflectors clean and make sure airflow paths aren’t blocked—otherwise you risk localized overheating. If your line runs extended high-output schedules, pair the lamp with a routine temperature scan to confirm uniformity across all zones.
