A handrail pultrusion die is a specialized manufacturing tool designed specifically for producing FRP handrail components. This precision-engineered heated steel forming tool shapes and cures resin-impregnated fibers into handrail profiles with exact cross-sections, enabling the continuous production of safety-compliant, durable handrail systems for construction and industrial applications.

How Pultrusion Dies Work

The Process

The pultrusion die applies controlled heat and pressure to transform raw materials into finished FRP profiles. Continuous glass fibers are pulled through a resin bath, then through the heated die cavity where the thermosetting resin cures under temperatures of 120-180°C. This creates a rigid, dimensionally accurate composite profile. For a detailed overview of the complete equipment for pultrusion process, including dies, pullers, and cutting systems, explore our comprehensive equipment guide.

Key Functions for Handrail Manufacturing
