Pultrusion: The Strength Behind Superior PV Frames
In solar, every component must last. The frame, as the module's backbone, faces decades of weather. So why do top composite PV frames use pultrusion?
Because it's perfect for the profile.
PV frames are long, straight profiles. Pultrusion is ideal: fibers are drawn through resin, then a heated die, curing continuously into a solid, precise shape.
The pultrusion advantage:
Stronger Directionally: Fibers align lengthwise (0°), creating a robust "spine" for high structural strength—unlike random fiber in molding.
Built for Efficiency: Enables fast, continuous production of long profiles, cutting waste and cost.
Precision & Stability: Curing in-die ensures dimensional accuracy, less warping, and reliable assembly.
Right process, right part:
Flat sheets use molding; complex parts use injection. For long structural profiles, pultrusion is the clear choice.
