Getting Your SACMI Blow Molding Lamps to Actually Keep Up

If you’re running SACMI rotary machines, you know they don’t exactly “take it slow.” Everything happens in a blur. Your preforms have a tiny window—literally milliseconds—to hit the exact temperature they need. When your IR lamps lag during start-up or can’t keep the pace during a cycle, you see it immediately in the product. You get those annoying thin spots in the walls or “pearling” that ruins a whole batch of bottles. It’s frustrating, and it’s expensive.

On a blow molding line, the heating tunnel is the heartbeat. If the lamps aren’t pulling their weight, preforms heat unevenly, and the blow molder spends the shift chasing scrap. We make Sidel heater lamps in China to the same OEM specs, so the machine runs the way it was designed to run.

What matters under the hood

These are straight-up Sidel replacements: short-wave infrared emitters with quartz tubes, rated 2400–3200 W, 220–240 V, and the standard R7s connector. We match the filament geometry and the reflector layout to the original footprint, so the irradiance distribution across the preform neck and body stays where it should. Every unit gets tested for spectral output, temperature rise time, and power factor. We also run life tests at full load—5,000+ hours is typical, with output dropping less than 5%.
