This FRP pultrusion production line uses closed-loop servo pulling and segmented heating dies to continuously manufacture constant-cross-section composites including round rods, square tubes, flat bars, and custom structural shapes. The system processes glass, carbon, or aramid fibers with polyester, vinyl ester, or epoxy resins at pulling speeds up to 1.2 m/min. Key features include automatic resin injection (replacing open bath), flying saw with dust extraction, and real-time pulling force monitoring to detect early gelation or fiber breakage. Typical applications include cable management ladders, chemical grating, tool handles, and highway drainage profiles. The line supports quick die change via hydraulic clamping, reducing model switchover to under 40 minutes.Engineered for consistent cross-section geometry across long production runs, this pultrusion line integrates a cantilever-style creel rack, a closed-loop resin bath with anti-drip nozzles, a multi-zone infrared heating tunnel, and a servo-hydraulic pulling unit. Unlike conventional lines, it features real-time line speed to heating temperature correlation – automatically adjusting heat output when pulling speed fluctuates, thereby preventing under-cured or charred surfaces. The optional in-line post-forming station allows punching or embossing of FRP profiles immediately after curing, eliminating a secondary operation. Delivered with pre-tested control cabinets and assembly drawings, the line can be commissioned within two weeks on-site.

Product Advantages
Low-Resin-Pool Die Architecture
Reduces stagnant resin accumulation inside the die, cutting material waste by 10–12% and minimizing black spec defects on light-colored profiles.
Independent Multi-Zone Heating
Each die segment (pre-heating, gelation, curing, cooling) has separate PID control, preventing internal stress and warpage on thick-walled sections up to 30mm.
Servo-Driven Reciprocating Puller
Delivers ±1% pulling force stability, crucial for hybrid profiles with carbon fiber or continuous strand mat layers. No profile slippage or fiber wrinkling.
Auto Cut-to-Length with Counter-Cutter
Cutting saw travels with the profile at line speed, producing square, burr-free ends for precision assembly – supports lengths from 2m to 12m with ±1.5mm accuracy.
Remote Recipe Management
Store up to 200 profile recipes (heating profile, pulling speed, cut length) in PLC. One-click changeover when switching between solid round bars and hollow square tubes.
Compact Footprint Layout
Linear configuration from creel to stacker saves 25% floor space compared to L-shaped or U-shaped pultrusion lines – ideal for workshop expansions.
FRP Dust Control System
Enclosed cutoff station with dual HEPA filters captures >99% of airborne glass/resin particles, improving OSHA/national workplace safety compliance.
