MANUFACTURING CAPABILITY

Controlled production from design to sea

Wageningen, Gawn and Kaplan fixed-pitch propellers are engineered for the vessel duty profile using analysis software, AMD and CAD/CAM workflows. Project-specific production complements the standard model families.

EIGHT CONTROLLED STAGES

The manufacturing journey of a propeller

Each stage is planned to secure the geometry and material quality required by the next operation.

  1. 01
    Computer-aided marine propeller geometry design
    Eriş production archive · 01

    Design and propeller selection

    Vessel, engine, gearbox and duty profile are assessed together; analysis results are combined with manufacturing experience to create a standard or project-specific geometry.

  2. 02

    Pattern production

    AMD and CAD/CAM data are transferred to the production pattern; the blade geometry is prepared on CNC machinery before moulding.

  3. 03

    Moulding

    Experienced craftspeople prepare moulds matched to the production pattern for propellers in the 100–2500 mm diameter range.

  4. 04
    Bronze marine propeller casting with an electric furnace
    Eriş production archive · 04

    Controlled casting

    Manganese bronze and nickel-aluminium bronze (Nibral) options are cast under control using electric-furnace infrastructure with up to 2500 kg capacity.

  5. 05

    Turning and machining

    The cast hub and blades are machined on horizontal and vertical equipment to bring connection details and blade geometry to their dimensional targets.

  6. 06
    Hand finishing and surface refinement on a propeller blade
    Eriş production archive · 06

    Hand finishing and surface refinement

    Experienced craftspeople hand-finish the blade surfaces to their final geometry and target surface quality.

  7. 07
    Final inspection of a machined propeller blade
    Eriş production archive · 07

    Static balancing and final inspection

    Dimensions, blade surfaces, material condition and static balance are checked before the final inspection defined by the project scope is completed.

  8. 08

    Protective packing and dispatch

    After final inspection, the blade edges, surfaces and hub connection are secured and wrapped before the propeller is prepared for dispatch in a wooden crate.

ISO · KLAS · MALZEME

Manufacturing to ISO and class tolerances

Standard model cards are specified as ISO 484 Class II. Class supervision, material analysis and certified production options are evaluated according to project requirements.
