The 700mm, 1200W Halogen Lamp That Keeps Your PET Blowing Line Humming

We built this 700mm, 1200W halogen heating lamp to be the direct replacement your PET blowing machine is waiting for. Its one job? Deliver steady, intense heat to pre-warm PET preforms so they stretch evenly when it counts. If your old halogen tube finally gave up, this one slips right in. No machine modifications. No downtime headaches. Just get the line back up and running.

Power, voltage, and fit: what actually matters

We chose 1200W because that’s the thermal sweet spot most PET blowing machines expect. It hits preforms with enough radiant power to reach process temperature fast—without pushing your heater circuit too hard. And the 700mm length? That’s about full-zone coverage. You get even heat across the preform neck and body, so you’re not fighting hot and cold spots. One thing to get right before you order: voltage. These lamps typically come in standard options, often 230V or 240V. If the voltage doesn’t match, performance gets shaky and the lamp won’t last. This is a high-density heater, so it gets hot quickly. That means airflow and reflector condition matter more than you might think. If cooling is weak, the lamp runs hotter, and output can drift over time.

Inside the build: halogen, quartz, and a connector you can trust

Inside, a halogen capsule sits inside a quartz envelope. The halogen cycle helps keep the filament stable at high temperatures, which supports consistent output over the life of the lamp. Quartz handles the heat and takes the thermal shock of repeated heat-up and cool-down cycles without cracking. We use an R7s connector because it gives you a secure, two-contact fit in the machine socket—stable enough to carry a 1200W load without getting sloppy over time. The ceramic base and quartz body are made to keep going, cycle after cycle. You may notice the outer quartz has a coating. It’s there to shape the spectrum and keep more heat focused on the preform. That’s a practical trade: better heat retention for the job, but it also means the lamp surface runs hotter. So clearance and shielding are worth paying attention to.

Why this matters on the blowing floor

In PET blowing, the lamp is the first domino. It has to deliver repeatable heat before the preform stretches. When the heat profile is stable, you see fewer rejects from uneven wall thickness and weak stretch points. With 700mm of coverage and 1200W of power, you get more uniform heat across the preform zone. The payoff is consistency—cycle after cycle.

Installation is the easy part

Install is straightforward. Match the voltage, line up the R7s pins, and seat the lamp fully in the reflector. Keep the reflector clean and make sure airflow is doing its job. It’s a drop-in replacement, but it still leans on the machine’s cooling and electrical health. If your line runs hard—especially 24/7—plan on replacing the lamp on a schedule. High heat density is powerful, and it does come with maintenance.
