What is an FRP Pultrusion Machine?
An frp pultrusion machine automates the continuous manufacturing of Fiber Reinforced Polymer (FRP) profiles by pulling glass fiber rovings—impregnated with resin matrices—through a heated die, forming complex cross-sectional shapes. It ensures uniformity, strength, and dimensional stability, outperforming manual lay-up or filament winding for high-volume standardized products.
Types of Pultrusion Machines
- Fiberglass pultrusion machine: Tailored for glass-fiber composites, robust for infrastructure, supportive of custom profiles.
- GRP pultrusion machine: Specializes in manufacturing Glass-fiber Reinforced Plastic elements; meets water treatment and cable tray requirements.
