Quality Control Stages
1. Incoming Material Inspection
Raw material (stainless steel bars/ingots) is verified by spectrometer to confirm material composition before casting.
2. Process Control
Parameters such as shell quality, pouring temperature, and cooling rate are monitored throughout production.
3. Dimensional Inspection
Critical dimensions are verified using calipers, micrometers, and CMM (Coordinate Measuring Machine) for precision parts.
4. Mechanical Testing
Hardness testing is performed to verify material hardness meets specifications.
5. Pressure Testing
Pump and valve castings that require pressure tightness undergo pressure testing.
6. Final Inspection
Final visual and dimensional inspection before packaging and shipment.
Testing Equipment
- Spectrometer: Material composition analysis
- CMM: Precision dimensional measurement
- Hardness Tester: Material hardness verification
- Pressure Tester: Pressure testing for pump/valve castings
