Rod Extrusion Lines

At Fastosi S.r.l., we design and manufacture state-of-the-art rod extrusion lines engineered for the continuous production of high-precision solid and hollow circular-section plastic semi-finished products. Built on decades of Italian engineering expertise and Made in Italy manufacturing quality, our extrusion plants deliver exceptional performance, tight dimensional tolerances, and void-free material consistency across a broad spectrum of standard, engineering, and advanced fluoropolymers.

Advanced Engineering for Solid and Hollow Rod Extrusion

Fastosi’s rod extrusion lines are specifically developed to solve the technical challenges inherent in heavy-wall and large-diameter plastic profile extrusion—such as internal stress buildup, shrinkage voids (blowholes), and material degradation.

Key Capabilities & Specifications:

• Output Capacity: Up to 40–50 kg/h depending on polymer type and die configuration.
• Calibrator Range: High-precision Teflon and lapped calibrators from 5 mm to 300 mm (0.25″ to 12″).
• Hollow Rod (Tube) Extrusion: Equipped with custom internal calibrators enabling hollow rod production with wall thicknesses starting from 10 mm (0.5″) upward.
• Dual Standard Systems: Extrusion dies and sizing units available natively in both Metric and Imperial configurations.

Processable Thermoplastics & Polymer Versatility

Our rod extrusion lines feature custom-engineered screw geometries, specialized barrel linings, and multi-zone thermal control systems to process complex thermoplastics with different rheological behaviors:

Engineering Plastics (General Mechanical Engineering)

Optimized for high rigidity, wear resistance, and high-speed CNC machining:

• POM-C & POM-H (Polyacetal / Delrin)
• PA6, PA66, & PA12 (Polyamides / Nylon)
• PET, PBT, PP, & PE (HDPE / UHMW)

Super-Engineering Plastics (High-Temp & Critical Applications)

Designed to handle extreme thermal loads and structural requirements with minimal stress:

• PEEK, ULTEM (PEI), PPS, PSU, PPSU, & PC (Polycarbonate)

Ultra-Performant Fluoropolymers (Aggressive Environments)

Specialized anti-corrosion extruders featuring high-nickel alloy barrels (Hastelloy / Inconel) for highly corrosive resins:

• PVDF, PFA, ECTFE, & PCTFE

Reinforcements & Additives: All Fastosi rod extrusion lines can process polymers filled with glass fibers, carbon fibers, PTFE, graphite, and other functional additives.

Key Technical Features & Line Modularization

Every rod extrusion line manufactured by Fastosi can be tailored to match your specific production environment and target dimensions:

• Stress-Free Cooling & Calibration: Multi-stage temperature-conditioned calibration baths that prevent internal stress, ensuring perfect dimensional stability for subsequent 5-axis CNC machining.
• In-Line Post-Processing Options: Seamless integration of in-line annealing ovens, automatic flying cutters, haul-offs, tilting tables, and material loading systems.
• Industry 4.0 Touch-Screen Interface: Complete line management via an intuitive touch-screen panel. Store, recall, and fine-tune specific extrusion parameters (temperatures, screw RPM, haul-off speed, pressure profiles) for zero-scrap product changeovers.
