ir lamp halogen heating for pet blowing machine

May 22, 2026

Introduction

Let’s get straight to it. We build halogen infrared lamps for one purpose: PET blowing machines. In that world, you need heat that’s fast, focused, and absolutely reliable. These lamps put the heat right where you need it—on the preform. The surrounding machine stays cool, which is a huge relief. It means you get a heating pattern you can count on, cycle after cycle. Your production stays fast, and scrap just disappears.

Technical Deep-Dive

Here’s the thing about PET blowing: you need serious power. That’s why we spec these lamps at 2500W to 3000W. That kind of punch gives you the quick temperature jump you need for a clean, consistent parison stretch. We run them at 400V, and that makes a real difference. Same power, but lower current. So your wiring can be thinner, you get less voltage drop, and the terminals stay cooler. And the 300mm active length? It’s a perfect match for the preform zone. You heat the neck and body evenly, without wasting a single watt on the clamp area.

Material & Design

The halogen cycle does the quiet work that keeps everything stable. It keeps the quartz envelope clear and holds the filament temperature steady, so the output stays consistent through a long shift. We also add a reflective coating to the quartz. It pushes more infrared energy forward, so the preform gets the full force of the heat. And when it’s time to swap a lamp, the R7s base makes it simple. It’s a tough, industrial connector that handles the heat, so a replacement is just a quick plug-and-play. The compact size also means you can drop these right into your existing reflector setup with almost no fuss.

Application & Benefits

You need heat fast, but you absolutely can’t cook the machine. That’s the balance, and these halogen IR lamps nail it. They deliver intense, directional heat that responds instantly, so you can fine-tune each zone without slowing the line. Just keep a couple of things in mind. That high power density means you need proper cooling and good airflow around the lamp and reflector. Stick to the rated voltage and keep the lens clean, and you’ll get stable, reliable heat that holds your process steady, day in and day out.
