Medium Wave Carbon Fiber Heat Lamps for PET Bottle Blowing

We built these medium wave heat lamps with one job in mind: keeping your PET blow molding line moving. They zero in on the preform, hitting it with fast, focused heat so the polymer hits the perfect stretch temperature—without turning the rest of the machine into a sauna.

Power and Output, Without the Fluff

These run on high voltage, usually 400V, because that’s what it takes to deliver the kind of punch industrial PET heating demands. A 2500W output packed into a 300mm length means serious watt-density. What does that feel like on the line? It means the lamp wakes up in seconds. It keeps pace with the blowing machine’s breakneck cycle. But here’s the thing: that kind of power needs respect. You’ve got to make sure the cooling and shielding are up to the task, so the area around the heating zone stays manageable.

The Materials That Make It Tick

At the heart of these lamps is a carbon fiber heating element, tucked inside a quartz tube. Carbon fiber gives you steady infrared output and handles rapid heating and cooling way better than old-school wire coils. The quartz envelope? Essential. It lets the medium wave infrared through cleanly and shrugs off thermal shock. And the R7s connector? That’s the standard for this footprint, so swapping one in is a straightforward, drop-in job.

Why It Works on the Floor

On the PET bottle blowing line, the lamp focuses squarely on the preform and heats it evenly. The medium wave spectrum gets into the PET material the right way—heating from the surface inward—without scorching. The payoff is consistent wall thickness and material distribution. You get a heating component that can take the grind of 24/7 production, with output that stays predictable. That kind of reliability makes process control simpler and keeps surprise downtime from wrecking your day.
