Energy saving IR emitter for blow molder

Preform heating is where you quietly burn money on the plant floor. Old halogens run hot, pull too much power, and still leave you chasing uneven wall thickness. We swapped that inefficient heat for targeted IR tuned for PET stretch blow molding. The payoff is repeatable temperature, lower kW draw, and fewer lamp changes. What matters technically We build the emitter around a short-wave quartz tube with a high-purity tungsten filament, so response is fast and output stays stable across the heating tunnel. Specs line up with OEM requirements: 1200–2400 W, 220–240 V, standard R7s connector, and the right arc length for a direct 1:1 fit. The spectral profile heats the preform surface quickly without overheating the neck, which improves thermal uniformity and supports consistent biaxial stretching. Here is why it works in real production. This emitter drops into your existing blow molder with no rewiring or bracket changes. It fits Sidel Matrix, Krones Contiform, and Husky HyPET platforms, and it also fits SIPA and SACMI machines that share the same lamp interface. In practice, you see lower kWh per thousand bottles, less load on cooling, and fewer rejects from thermal stress. We have units running 5,000+ hours with less than 5% output drop, so you spend less time on maintenance and more time producing. A few shop-floor notes. Installation is straightforward, but clean handling matters. Wipe the quartz with alcohol, don’t touch the glass, and double-check the voltage matches the label. The emitter is optimized for PET preform heating; if you run other materials, confirm the temperature profile against your machine settings. And yes, energy use drops—but the hot zone is still there. Always follow lockout procedures and let the lamp cool before replacing it.
