Core Marine Product Solutions

We specialize in high-thermal load, high-sealing, and high-fatigue core components.

1. Marine Engine Blocks & Cylinder Heads

Our flagship manufacturing line handles the most complex geometries in marine propulsion.

Material Versatility: We offer flexible production for Vermicular Graphite Iron (CGI-500), High-Strength Ductile Iron (QT700-10), Grey Iron (HT300), and Aluminum Alloys.

Extreme Precision:

Cylinder Bore Cylindricality: ≤5µm.

Crankshaft/Camshaft Hole Coaxiality: ≤20µm.

Machining Pass Rate: ≥99.5% with critical dimension Cpk ≥1.67.

Smart Production: Our dual-metal compatible lines can produce grey/vermicular iron blocks and aluminum heads simultaneously, with real-time adjustment of sand-iron ratios.

2. Double-Wall Pipes & Manifolds (Fuel & Exhaust Systems)

Safety and leak prevention are paramount for marine fuel lines and exhaust systems.

Complex Thin-Wall Expertise: Leveraging our expertise in "complex thin-wall irregular shaped parts", we manufacture high-integrity double-wall pipes and exhaust manifolds.

Leak-Free Guarantee: We utilize CAE solidification and flow field simulation to optimize pouring, ensuring dense material organization. This significantly enhances fatigue life and leak resistance for high-pressure fluid transfer.

3. Comprehensive Marine Portfolio

Beyond engines, we supply critical castings for the entire vessel:

• Propulsion: Gearbox housings, Flywheel housings, Bearing seats.

• Pumps & Valves: Pump casings, Valve bodies (Gate, Butterfly, Check), and Impellers.

• Deck Machinery: Winch housings, Rudder system components, and Anchoring equipment.

Intelligent Casting (3D Printing + Traditional)

We don't just cast; we innovate. Our hybrid approach combines traditional strength with digital flexibility.

3D Sand Printing: Complementing cold core and vertical/horizontal shooting, our 3D printing technology allows for integral molding of large, complex sand cores without expensive tooling.

Advanced Smelting: We use high-strength Ni-Cr-Mo alloy formulations, improving material density and fatigue life by over 30%.

Precision Machining

Micron-Level Accuracy: Our CNC fleet ensures repeat positioning accuracy of ≤0.002mm, with key hole system coaxiality of ≤0.01mm.

High Flexibility: We support high-mix, low-volume production with changeover times under 15 minutes.

Rigorous Quality Control

We employ a "Zero Defect" policy backed by a suite of inspection technologies:

• Dimensional: CMM, Laser Trackers, and Profilometers.

• Physical/Chemical: Spectrum analysis (20 elements), Carbon/Sulfur analysis.

• Non-Destructive Testing (NDT): Magnetic Particle, Fluorescent Penetrant, X-Ray, and Ultrasonic testing to ensure zero internal flaws.
