Metal-to-plastic conversion of a pump housing
Agritech · New Zealand
The challenge
An agritech company’s cast-aluminium pump housing was expensive, heavy and prone to corrosion in fertiliser applications.
Our approach
- Feasibility and material selection (glass-filled PA66)
- Four parts consolidated into one moulding
- FEA for pressure, creep and fatigue
- Prototype pressure and life testing
- Overseas tooling and PPAP management
Results
What changed.
Part cost reduced by 42%
Weight reduced by 55%
Corrosion failures eliminated
Payback on tooling in 7 months
