Cylinder Head
Factory
The Cylinder head is a mission‑critical engine component subjected to severe thermal & mechanical loads. It features intricate internal structures: intake/exhaust ports, cooling jackets, injector seats and complex multi‑cavity geometry.
Our sand 3D‑printing technology produces integrated sand molds & cores with zero tooling. Paired with Rumo® Compacted Graphite Iron (CGI), the material delivers tensile strength close to ductile iron and far better thermal‑fatigue performance than grey cast iron, effectively solving cylinder‑head cracking under high‑boost conditions.
Core Technology Advantages
Shortened R&D Cycle
No mold restrictions, complex structures formed in one piece. R&D cycle shortened by 70%.
High-Efficiency Production
Sand moulds printed in 24-48 hours — first casting sample in about 2 weeks
High Precision & Quality
Precise control of sand mold dimensions, avoiding localized looseness and sand inclusions.
Green Production
Recyclable sand materials,low-emission, high regeneration rate of waste sand.
Compacted Graphite Iron (Rumo®)
The graphite morphology is neither fully flake‑like(grey iron) nor fully spherical (ductile iron), but rather short, thick worm‑like shapes — truly a "middle‑ground" material, combining the castability of grey iron with the high strength of ductile iron.
🔴 Core Performance Characteristics
🔻Comprehensive Mechanical Properties:
Strength and stiffness between grey and ductile iron‑ tensile strength close to ductile iron, far above grey iron.
🔻Excellent Thermal Resistance:
Good thermal conductivity, outstanding thermal fatigue resistance; withstands rapid heating and cooling‑ this is the core requirement for cylinder heads under high‑boost conditions.
🔻Castability:
Superior to ductile iron, good fluidity, low shrinkage tendency‑ ideal for complex internal cavity formation
🔻Cost-Effectiveness:
Moderate production cost, high cost-performance ratio – achieves near-ductile-iron performance without high alloying costs
