FRP Pultrusion Die System

High-Precision Industrial Composite Forming Tooling

The FRP pultrusion die system is a core forming component in pultrusion production lines, used to continuously shape fiberglass, resin, and fillers into high-strength composite profiles under continuous pulling force. It directly determines dimensional accuracy, surface quality, and structural performance, making it a critical element for producing high-grade industrial FRP profiles.
