The Heaters We Built for PET Blowing
We designed this ODM heater from the ground up for one job: heating PET preforms. The whole setup is focused on hitting that high thermal demand without messing around. The S-shape isn’t just for looks. It gives you a lot of radiant surface in a tight space, so you get even heat across the preform walls. And it slips straight into your existing blow molding machine. No major overhauls. No headaches.
Why Carbon Fiber Infrared Makes Sense
Here’s the heart of it: a carbon fiber element that fires up fast and stays steady. Unlike quartz, it heats up almost instantly and holds a stable shortwave output. That’s perfect for getting heat into PET quickly, without wasting energy or dragging out cycle times. The filament is tough enough to handle repeated heating and cooling. But it does need a clean, stable voltage supply—otherwise you risk burning it out early.
How It Fits Into Your Blow Molding Line
On the line, this heater does the heavy lifting in preform conditioning. The S-shape wraps around each preform, delivering heat that stays uniform. That means fewer weak spots and more consistent bottle wall thickness, every time. Because it’s ODM, we match your machine’s exact connectors and dimensions. It’s a true drop-in replacement. Just keep one thing in mind: the heat density is high, so you’ll want a cooling system that’s properly sized. It keeps the surrounding machine temperature under control.
