On the floor, a sloppy heating profile on your SIG Blomax 6 doesn’t just throttle the line—it manufactures scrap. Preforms that come out of the tunnel under-baked give you brittle bottles and stretch that’s all over the place. Overheating, on the other hand, eats energy and burns through lamp life. What you need is a replacement that hits the OEM thermal curve, not a best guess. What matters under the hood We build the Blomax 6 replacement as a short-wave infrared halogen emitter, tuned to PET’s absorption band so the heat lands evenly and fast. The quartz envelope takes the thermal shock inside the heating tunnel, and the R7s base drops straight in—no adapters. The specs stay true to the machine: wattage density, voltage tolerance, and filament geometry all match. That keeps the preform body and neck at the right temperature profile, so material distribution stays consistent during stretch blow molding. Here’s why it plays nice on the line. Compatibility is baked into the lamp. It’s a direct fit for the SIG Blomax 6, and it also covers the broader SIG family—Matrix, Contiform, and HyPET platforms. That lets you standardize spares across multiple blow molders, which simplifies inventory and cuts downtime. In practice, you get fewer lamp changes, stable preform temperature, and bottle quality that behaves predictably. Energy stays close to baseline because the emitter delivers the heat you need without overshooting. A few shop-floor details that make the difference. Installation is straightforward, but alignment is everything. Set lamp position and reflector geometry to the OEM spec; even a small offset can create hot and cold zones that show up as thickness variation. Handle the quartz with clean gloves—fingerprints turn into hot spots. These lamps run hot, so make sure your cooling airflow matches the machine’s design. Expect long life—units have run 5,000+ hours with less than 5% output drop—but keep a schedule to check terminals and connectors. Voltage drop there can drift the heating curve when you least need it.
