Component-focused process review
Pressure-tight components require the casting structure, machining depth, sealing surfaces and final verification to be treated as one system. Machining can expose discontinuities that were not connected to a surface before cutting, so test planning should reflect the finished geometry rather than only the as-cast condition.
Common purchasing priorities
- Design pressure, test pressure and allowable leakage
- Gas or liquid test medium and test sequence
- Wall transitions, isolated heavy sections and machining depth
- Sealing surfaces, ports and threaded connections
- Material verification, NDT and traceability requirements
- Test timing before and/or after final machining as specified
Integrated supply
Investment casting, CNC machining, NDT and pressure/leak testing can be coordinated under one route so casting condition and finished sealing performance are evaluated together.
Start with the application
Provide the pressure and temperature range, media, leakage criterion, material, pressure-boundary areas, machining depth near those areas and the required NDT and pressure/leak-test procedure.
