Innovative Mold & Preforming Design for FRP Pultrusion Manufacturing

At ‌Hengshui Hongwo, we specialize in precision engineering of pultrusion molds and preforming systems for diverse FRP profiles, including FRP Rod, FRP Pultruded Round Tube, FRP Square Tube, FRP I Beam, and FRP U Channel. Our proprietary technologies ensure optimal structural integrity and dimensional accuracy across all product lines‌.

Innovative Mold & Preforming Design for FRP Pultrusion Manufacturing

‌Core Design Principles‌

1. ‌Preforming Optimization‌
   • Multi-stage preforming systems withwear-resistant fiber-guiding grooves andchamfered yarn ports) enable seamless transition from flat reinforcement mats to complex profiles like FRP Angle and FRP Rectangular Tube‌.
   • Transition zones (0.5–1.5m) progressively align fibers to minimize stress concentration‌.
2. ‌Mold Engineering Excellence‌
   • Forged mold steel undergoes quenching and nitriding to achieve >60 HRC hardness, critical for high-wear components in FRP Pultruded Round Tube production‌.
   • CNC-machined cavities ensure ±0.1mm tolerance for FRP Square Tube and FRP I Beam cross-sections‌.

‌Material-Specific Solutions‌

• ‌FRP U Channel‌: Layered fiber orientation with UV-resistant resin infusion prevents delamination under cyclic loading‌.
• ‌FRP Rod‌: Pre-compacted roving bundles reduce voids by 30% compared to conventional designs‌.

‌Quality Assurance‌

Our ISO-certified process integrates real-time load-bearing tests for FRP Angle and automated thickness monitoring for FRP Rectangular Tube, ensuring compliance with ASTM standards‌.

By synergizing advanced preforming logic with hardened mold systems, we deliver FRP profiles that outperform steel in corrosion resistance (5–8× lifespan) while maintaining 1/4 weight‌. Partner with us to optimize your structural applications with engineered pultrusion solutions.
