3-bladed Propeller

Technical Specifications & Advanced Propulsion Engineering

Elite Quality Verification for Marine Propulsion Systems

Propellers operate under constant cyclic loading and high shear stress. To avoid catastrophic blade failure out at sea, every unit undergoes elite quality metrics:

• Rotational Stability Calibration: 100% processed through Dynamic Balancing Tests to certify that asymmetric mass distribution is completely nullified, protecting your gearbox and shafting logs.
• Hydrodynamic Geometry & Angle Audit: Verified via specialized fixtures or CMM (Coordinate Measuring Machines) to ensure the pitch, rake, and profile of every blade perfectly match the CAD file blueprint.
• Blade Surface Micro-Defect Inspection: Conducted via Liquid Penetrant Testing (LPT) to guarantee that the high-stress root regions and thin blade edges are completely free of microscopic thermal tears.
• Metallurgical Characterization: Evaluated via Spectrometers to ensure exact 17-4PH element parameters, followed by optimized heat treatment to unlock maximum hardness and tensile properties.

Custom OEM / ODM Engineering for Modern Shipyards & Marine Designers

• Custom Fluid Dynamics Layouts: We custom-manufacture 3-blade, 4-blade, or custom geometric marine propellers and impellers based on your proprietary 3D digital technical data (STEP, IGES).
• Tailored Shaft Hub Fittings: Fully capable of pre-machining custom taper sizes, spline designs, or keyways according to your exact drivetrain assembly requirements.
• Certified Inspection Logs: Complete material certificates (EN 10204 3.1), mechanical test logs, and balancing data are packaged with every delivery.
