Pultrusion Mold of FRP Handrail

The Fiberglass Handrail Pultrusion Profile Mold is specifically designed for manufacturing FRP (Fiber Reinforced Plastic) profiles used in handrail applications. It employs the pultrusion process, which involves pulling fiber material impregnated with resin through a heated mold, resulting in the formation of profiles with a specific cross-sectional shape and size suitable for handrail use. FRP profiles offer numerous advantages, including lightweight construction, high strength, corrosion resistance, insulation properties, and fire prevention capabilities. As a result, they find wide applications in various industries such as electric power, chemical, construction, transportation, and more, particularly in the construction of handrail systems where durability and safety are essential.

1) Comfortable Grip

The handrail’s cross-section should feel comfortable to hold. Common shapes: round, oval, or flat-curved.

2) Non-Slip Surface

Add textured patterns to the surface to improve grip and prevent slipping in wet conditions.

3) Hollow Design

Keep the handrail lightweight but still strong enough to resist bending.

1) Easy Connections

Leave standard slots at the mold’s exit to help handrail pieces snap together quickly (e.g., puzzle-like joints or clip-in parts).

2) Hidden Cable Channels

If the handrail has lights or sensors, build grooves (≥8mm wide) into the mold to avoid cutting into the fibers later.

3) Modular Parts

Make the mold’s entrance guides and heating sections replaceable, so it works with different resins (like epoxy or polyester).

1) Clean the mold with ultrasound every 5,000 meters of production to remove leftover resin.

2) Fix worn areas with local plating or laser repairs to extend the mold's life up to 500,000 meters.
