Test method for Air Conditioning Stamping Parts
1, touch test
Wipe the surface of the outer cover with a clean gauze. Inspectors are required to wear a touch glove along the Air Conditioning Stamping Parts longitudinally close to the surface of the Air Conditioning Stamping Parts, this test method depends on the experience of the inspector. If necessary, it can be used to polish the suspected suspicious area and verify it, but this method is an effective quick test method.
2, Whetstone grinding
2.1, first clean the surface of the outer cover with a clean gauze, then polish the oilstone (20 × 20 × 100mm or more), where there is a circular and difficult to reach with a relatively small oil stone grinding ( For example: 8 × 100mm semi-circular Whetstone).
2.2, Whetstone particle size depends on the choice of surface conditions (such as roughness, galvanized, etc.). It is recommended to use fine-grained Whetstone. The direction of the polished stone is basically along the longitudinal direction, and the surface of the Air Conditioning Stamping Parts is well fitted, and some special places can also complement the lateral grinding.
3, flexible gauze grinding
Wipe the surface of the outer cover with a clean gauze. With a flexible sand net close to the surface of the Air Conditioning Stamping Parts along the longitudinal direction to the entire surface, any pitting, indentation will be easily found.
4, oil test
Wipe the surface of the outer cover with a clean gauze. And then evenly brush the oil along the same direction to the entire outer surface of the Air Conditioning Stamping Parts Put the finished oil stamping parts on the test under the strong light, it is recommended to put the stamping parts in the body position. With this method can be easily found on the stamping parts of the tiny pitting, deflated pond, ripple.
5, visual inspection
Visual inspection is mainly used to find the appearance of the Air Conditioning Stamping Parts and macroscopic defects.
6, seized inspection
The Air Conditioning Stamping Parts into the seized, according to the instructions of the operating instructions, the Air Conditioning Stamping Parts for testing.
