Inspection And TestRaw Material Inspection:1. Check the material supplier's mill test certificates2. Check the material's quantity, size, surface condition3. Conduct chemical analysis and mechanical property testProcess Inspection:1. Inspect single work-piece's dimension, levelness, benddegree, hole size, hole location, etc.2. Inspect the work-piece's welding result Cleaning Result Inspection:After the work piece pass the process inspection, then go to cleaning to wipe out its oil&grease, dust, and other contaminants. Inspection method:1. Visual inspection 2. Wipe test 3. Black light test4. Mirror test (if need)Assembly Inspection:After cleaning inspection is good, then assemble on set to inspect its overall levelness, dimension, etc.Water Test:Water test is a good way to check the distributor's working performance. The test items includes:1. Liquid height in trough2. Used time of one hole to fill the container3. Calculate the coefficient variance(CV)Package Inspection:1. Check the small parts quantity according to packing list2. Check the protect method of the internals
