Why Choose Kangshuo Marine Solutions?
We combine the agility of digital manufacturing with the reliability of heavy industry. Our facility operates with an annual capacity of 200,000 tons, backed by ISO 9001/IATF16949 dual-system certifications.
CCS Certified Authority: We have successfully obtained the Works Approval Certificate from the China Classification Society (CCS).
Full-Lifecycle Traceability: Every casting has a "Birth Certificate." We implement full digital tracking from raw materials to finished products, ensuring 100% compliance with international marine safety standards.
Rapid Delivery: Utilizing advanced 3D sand printing and cold core mechanisms, we have reduced the delivery cycle for new product core assemblies from 7 days to just 36 hours.
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.
Technology & Process: The Kangshuo Advantage
Intelligent Casting (3D Printing + Traditional)
We dont 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.
Global Standards, Local Service
