On the blow molding floor, preform heating is the first choke point. If the heating tunnel starts to drift, you’ll see axial splits, wall haze, and necks that are off-spec—then the whole line pays for it. We built clear quartz heating lamps to drop in place of the OEM halogen/infrared emitters on Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB blow molders. The geometry is 1:1, and the electrical match is right, so the machine sees the same load and the same profile. What matters, technically We run short-wave infrared through a high-purity clear quartz tube, pushing the filament hot and fast so it responds quickly. The lineup covers 240V/380V/480V and the wattages you actually run in preform heating zones, with R7s bases and matched reflectors to keep beam focus and temperature uniform across the tunnel. It comes up fast—full output in seconds—so you can chase cycle time without waiting for the heater bank to settle. Why it holds up in stretch blow molding In stretch blow molding, the preform needs a tight thermal window: hot enough to stretch, but not so hot it sags or thins out. These quartz lamps give repeatable heat with tight spectral control, and that shows up as fewer rejects and steadier bottle weight. On the floor, you get more consistent wall clarity, less scrap, and lower energy draw because the emitter heats on demand and holds setpoint with less overshoot. The practical details Install is straightforward—mount it, wire it, set the PID. Just verify the socket type, watt density, and airflow direction on your blow molder. Clear quartz runs hot, and output will drift over time like any infrared source, so keep spares on the shelf and stick to a reflector cleaning schedule. Treat it as a direct-fit replacement: match the spec, and the performance follows.
