Introduction
We built these halogen heat lamps for one reason: they work. They were born for the PET bottle blowing process. We offer three shapes—round, S, and U—so you can match the exact layout of your preform heating zone. The whole point is to get that fast, focused infrared energy right where you need it, so the material softens consistently every single time.
The Nitty-Gritty
These are serious, industrial-grade lamps. They run on high voltage, usually 400V, because that kind of power is what it takes to heat things up fast. We match the wattage to the lamp length and your cycle time, so even in a small space, you can get up to 2500W of heat. And those shapes—round, S, and U—aren’t just for looks. They let the lamp hug the path of the preform. That means the heat is even, all over, with no weak spots.
What’s Inside
At the heart of it is a shortwave infrared halogen element, tucked inside a quartz tube. The quartz is tough—it handles the sudden heat changes—and it lets that infrared energy pass through cleanly. We’ve also coated the outside with a reflective layer. This keeps the heat moving forward, where it’s needed. Less wasted heat means less strain on the parts nearby. The connector? It’s a standard R7s, a simple bi-pin design. That makes these lamps a direct replacement. You can swap them in and get back to work without rewiring the whole machine.
Why It Works for You
When you’re blow molding PET, you need heat on demand. Halogen lamps get hot almost instantly, giving you tight control over the preform stretch zone. No waiting around. That quick response keeps your line moving at a steady pace. Now, the catch is the intensity. This is a high-wattage lamp, so it throws off dense heat. Your machine needs proper cooling and shielding to handle it. But if you do, you get results you can count on. Reliable, repeatable, every time.
