OEM Production Carbon Fiber Heating Tube

Meet the OEM Carbon Fiber Heating Tube

We built these OEM carbon fiber heating tubes for engineers who need serious heat in a tight space—and need it to hold up, day after day, on a busy production floor. They’re designed to throw focused infrared energy exactly where you need it. Think demanding jobs like PET blowing and plastic welding, where heat has to be on point, every time. Inside, you’ve got a carbon fiber filament paired with halogen gas, all sealed inside a quartz tube and wired with a standard R7s connector. The result? A drop-in solution for replacing old, tired systems—or a dependable, repeatable choice when you’re building new equipment.

Power, Voltage, and Size—Without the Fluff

These tubes run at 400V and crank out 2500W, packed into a 300mm length. That’s a lot of heat in a small footprint. And it shows. They warm up fast and hold output steady, which is exactly what you want when timing is everything. The 400V rating isn’t arbitrary. It matches industrial control circuits, so you draw less current than with lower-voltage options. That makes wiring simpler and eases the job of sizing contactors. The 300mm length concentrates heat into a tight zone—perfect when your process needs precise thermal focus. But here’s the trade-off: 2500W at 400V means you’ve got real heat to manage. Make sure your machine has enough airflow or heat sinking. Keep nearby components cool, and you’ll keep the whole system stable.

What’s Inside—And Why It Matters

The carbon fiber filament sits inside a quartz tube, filled with halogen gas. That halogen cycle helps keep the filament stable at high temps, resisting blackening and keeping output consistent over the tube’s life. Quartz also handles thermal shock well and transmits infrared cleanly, so the heat gets where you need it—efficiently. Then there’s the R7s connector. It gives you a secure, two-ended termination that lines up with common industrial sockets. Installation is straightforward, contact stays reliable, and when it’s time to replace a tube, you’re back up and running fast. The end caps are built for repeated heating and cooling cycles, so you can wire it in and count on steady performance—without constant re-tightening or babysitting.

Where It Shines—And What You Gain

In PET blowing, these tubes deliver the fast, localized heating you need to warm preforms quickly and evenly. Same story with plastic welding, sealing, and thermoforming. A concentrated heat zone means better cycle times and more repeatable results. Because it’s an OEM configuration, you get a standardized component that fits cleanly into your machine design—with predictable dimensions and electrical behavior. You get high heat density without blowing up your machine footprint, and the R7s termination keeps assembly and service quick. Just remember: match your socket to the 400V rating, and make sure your cooling and insulation can handle the 2500W load.
