pets carbon fiber quartz heating lamp

May 23, 2026

Introduction

We built this carbon fiber quartz heating lamp to be a straight swap for the tough spots—especially on PET blowing and forming lines. It throws out fast, intense infrared heat in a small package, so you can speed up cycles without tearing up your layout or reworking the whole machine footprint.

The Details, Without the Fluff

Here’s the spec that matters: 400V, 2500W, and a 300mm active length. That combo packs a lot of heat into a short tube, which is exactly what you need when space is tight and heating zones are cramped. And that 300mm length? It gives you a heat pattern that lines up with standard machine cavities, so you can swap it in without re-engineering the line.

What It’s Made Of (And Why It Holds Up)

The quartz envelope handles wild temperature swings without cracking under thermal shock—way tougher than ordinary glass. Inside, the carbon fiber filament keeps resistance stable, so output stays consistent over time, even with frequent on/off cycling. And the R7s connector is a simple, proven two-pin setup. Installation is a drop-in job—no custom brackets, no headache. Just line it up and wire it.

Real-World Use and What It Gives You

On PET blowing lines, you need heat that hits fast and spreads evenly to soften the parison quickly. This lamp gets to target temperature fast, so warm-up time shrinks and your cycle times stay steady. But with 2500W packed into 300mm, you’ve got serious heat density. So make sure your machine’s cooling and airflow are set up right—protect the lamp and the surrounding parts by keeping everything within safe operating limits.
