Some comment factors for aluminum alloy products quality inspection:
1.Check the material’s specification according to the purchase order
2.Use appropriate measuring tools to measure each project to detection of different parts of not less than three times.
3.Hardness inspection: the inspection according to material of model checking is related to the effective data files, confirm what is the hardness, using hardness tester for testin, sampling of the surface of the material requirements must conform to the requirements of the relevant durometer measurement.
4.Appearance inspection: mainly on the material appearance shape, inspection of surface defect: For appearance’s defects, can use visual inspection, for High Precision Process, it is not easy to detect the shape of the demand by visual inspection, it needs appropriate measuring tool to measure.
5.Surface electroplating: require surface electroplating is good, no oxidation, scratches, and other bad plating phenomenon.
6.Common defects following:
1)Bending: bending is rolled material.In the length or width is not flat, is in the shape of the curve.
2)Reverse: strip rolling material along the longitudinal axis twisted into a spiral.
3)Surface crack: refers to the metal object surface crack
4)Fold:It is the metal in the process of hot rolling or forging forming of a kind of surface defect, surface or double metal layers, with each other in a straight line or curve.
5)Package:Some chemical products should be packaged by special material to prevent oxidation or other bad effects.And the fragile products should be packaged by foamed plastic in order to avoid the pressing or dropping damage.
