IV. Manufacturing Process: Step-by-step Technical Illustration

Raw Material Selection – Only certified pig iron/alloy scrap with MTR traceability is used for cast iron post collars, ensuring Gra-Iron up to EN-GJL-200 or ductile iron (EN-GJS-400).
Molten Iron Preparation – Cupola/electric induction melting for precise temperature and chemistry control.
Pattern Making & Sand Molding – Custom CAD patterns for decorative collars, sand tested for strength (>30N/cm²).
Casting – Liquid iron poured into pre-heated sand molds; advanced control prevents cold shuts and porosity.
Knockout & Fettling – Molds broken, castings cleaned, risers/flash removed with vibration tables, shot blasting for smooth collars.
Heat Treatment (optional) – For ductile iron collars: controlled cooling to ensure graphite nodularity per ISO 1083.
Precision Machining – CNC turning/milling; tolerances ±0.3 mm, holes or slots added as per fence/post specs.
Surface Finishing – Powder coated, black/gray painted, or anti-rust zinc (per ISO 1461), Ra 1–3 μm finish.
Quality Inspection – Dimensional (CMM), tensile, compression, and corrosion tests (ISO/EN/ASTM), checked per batch.
Packing & Shipping – Custom crates, rust-protective film, and palletization for safe delivery worldwide.
