heat lamp carbon fiber ir quartz glass for pet bottle blowing

June 2, 2026

We built these carbon fiber infrared heat lamps with one thing in mind: the PET bottle blowing process. The whole point? Get intense, focused heat right where the preform needs it—instantly. Inside, you’ve got a quartz glass shell holding a carbon filament that runs hot, clean, and responds the second you need it. Perfect for the pace of the blow molding floor. Here’s the thing about the specs—they’re built for the real world. Each lamp runs at 400V and 2500W, giving you the watt density to heat preforms fast without having to oversize the heater zone. And at 300mm long, it gives you a tight heat footprint that lines up with standard preform necks. That means you’re only heating the part that matters. The upshot? Shorter cycle times and less wasted energy heating the air. Quartz glass handles the heat and shrugs off thermal shock like it’s no big deal. The carbon filament puts out shortwave infrared that sinks into PET efficiently, heating from the surface inward. A reflective coating on the quartz pushes more of that energy forward, so more of it lands on the preform and less drifts off into the surroundings. And the R7s connector? It’s tough, wires up fast, and holds steady even with vibration—so you can swap it in and get back to work. On the PET blowing line, you need heating you can count on to hit that perfect stretch profile. These lamps give you quick, controllable heat, so you can set tight temperature windows and run consistent cycles. The carbon fiber build stands up to repeated on/off cycles without burning out. Just keep in mind: because the watt density is high, make sure your machine’s cooling and clearance are up to the task of managing ambient heat. We designed these lamps to be a solid, practical upgrade—more control, steady output, and an install you can trust shift after shift.
