  • Integrated sub-assembly operation, eg. Seal insertion, core plug insertion, automatic screw driving etc.
  • Sub-assembly component performance and function tests, eg. Electrical testing of sensors, switches and devices.
  • Multi-cavity testing, eg. Combined vacuum and positive pressure testing , internal leakage testing, low and high pressure testing.
  • Serial numbering and data logging for product traceability, SPC and quality control requirements.
