Halogen Heating Lamps for PET Blowing: Power, Precision, and a Clean Install
We built these halogen heating lamps for one reason: PET blowing. You need heat that jumps into action fast, stays under your control, and never scorches the preform. These aren’t bulky convection heaters. They’re shortwave infrared lamps. Heat on demand, exactly where you need it.
Power, Voltage, and Size—Kept Tight and Smart
A typical unit runs at 2500W and 400V, packing serious heat density into a small footprint. The 300mm length focuses the energy right where the parison stretches—the neck and shoulder. And because it’s high voltage, the current draw stays manageable. No need to upsize wiring or contactors just to get the heat you want.
Quartz, Coating, and a Connector That Just Clicks
The quartz envelope runs hot and clean, and the internal halogen cycle keeps output steady over time. No drift. No surprises. We added a reflective coating on the outside to push energy forward, so less heat gets wasted into the frame. And for the install? R7s bases. Drop-in replacement, no tools. In most blow mold fixtures, swapping a lamp is quick and painless.
What It Feels Like on the Line
In PET blowing, the lamp needs to hit temperature fast and hold steady, cycle after cycle. Shortwave infrared gets into the preform surface without overheating the core. That helps you keep wall thickness consistent and cut down on rejects. But here’s the part you can’t ignore: that kind of heat density needs a proper cooling path. Airflow. Or shielding. Either way, it keeps the lamp and nearby components at a safe temperature. It’s not just heat. It’s predictable heat—right where you want it, when you want it.
