Getting the Heat Right for Fiberglass Annealing

Most heaters you buy off the shelf just blast uniform heat everywhere. But if you’re in the middle of R&D for new fiberglass materials, “uniform” usually isn’t what you actually need. The real trick is power density. It’s all about controlling exactly where those watts land. You want the surface to hit that glass transition temperature without accidentally cooking the core of the material.

It’s more than just the size

Sure, we can make a heater longer or wider. That’s the easy part. The real magic happens when we look at the watt-per-centimeter distribution. We can build heaters with graduated power zones. Imagine hitting the lead-in edge with high heat and then tapering it off as the material moves toward the exit. It stops thermal shock in its tracks. Plus, you can tweak your annealing curve without having to mess with your line speed.
