Introduction
We built this 665mm, 2000W halogen heating lamp for one reason: to be the heat source your blowing machine has been waiting for. It slips right in—no fuss—and gets to work fast, heating up PET preforms with steady, reliable warmth. The result? A blowing cycle that runs smoothly, without that annoying temperature drift that throws off your day.
Power, Length, and Heat Density
Here’s the thing: at 2000W packed into a 665mm tube, you get serious watt density. That means rapid warm-up and precise control over the preform surface temperature. The length isn’t random, either—it matches the footprint of most machine windows, so you get full coverage without re-routing reflectors or wrestling with mounts. And the voltage? We picked it to match the control cabinet supply in your machine. That keeps wiring current lower and terminal temperatures sane—no overheated connections, just steady, confident performance.
Material & Design: Halogen, Quartz, and Connector Choice
Halogen technology keeps the filament running hotter and cleaner, which helps the output stay consistent over time. The quartz envelope handles rapid temperature swings like a champ, so repeated on/off cycles don’t cause thermal shock. The R7s connector is compact, two-contact, and snaps in quickly. It carries the full load cleanly—no extra adapters, no hassle.
Application & Benefits: PET Blowing Setups
In PET blowing, this lamp hits target temperatures fast, so you get repeatable stretch and wall thickness—the kind of consistency that makes your day easier. The 665mm size is a drop-in replacement in many machines, which means changeover is quick. But let’s keep it real: that high heat density needs proper airflow and a clean reflector. If those aren’t in place, nearby components can run hotter than expected. Keep air moving and surfaces clean, and the lamp does its job the way it was meant to.
