[GEFERTEC] Case study : propeller

22/10/21

PROPELLER

Propeller Gefertec

INFORMATION ON THE COMPONENT PART

  • Application : harbour craft propeller
  • Conventional manufacturing technology : casting process
  • Challenges :
    ▪ Long delivery time
    ▪ Poor quality of castings
    ▪ Subsequent changes can only be realized by manufacturing new moulds

ALTERNATIVES TO CASTING

MANUFACTURING WITH 3DMP® WAAM

  • Fast and fl exible procurement of the near-net shape blank as required
  • Subsequent adjustments can be easily implemented
  • Wider range of corrosion resistant materials available

MILLING FROM SOLID

  • High storage costs of wrought material
  • Long delivery times of wrought material
  • High utilization of milling centers
