People often need Aluminum Machining parts, a variety of specifications, sheet metal processing, different parts, different colors, different processes, we can support, please contact us for details.

For any sheet metal processing part, in the process of processing, due to improper operation or various other reasons, there may be some defects in the sheet metal processing part, and the processing of sheet metal shell is no exception. Therefore, we need to learn to identify whether there are defects in sheet metal shell processing, so that we can better deal with the problems that arise. So do you know how to identify whether there are defects in the processing of sheet metal shells? Here is a brief introduction for you:

To identify whether there are defects in sheet metal shell processing, you can mainly see the following aspects:

1. In sheet metal shell processing, exposed substrate means that there is no coating layer on the surface, the main reason is the leakage of spray and large area scratches.

2. The principles of paint flow and powder accumulation are roughly the same, except that the paint flow is generated when spraying paint, and the accumulated powder is generated when spraying plastic, both of which are caused by excessive spraying and excessive thickness.

3. The peeling off of the coating layer is mainly due to the insufficient bonding force between the coating layer and the substrate. The main methods for detecting the bonding force are impact test and cross-cut test.

4. Serious chromatic aberration refers to the inconsistent color of the same surface of the sheet metal shell processed products, and the chromatic aberration value exceeds.

5. The causes of surface scratches are relatively complex and run through the whole process of sheet metal shell processing and production, but they can be roughly divided into two categories: one is the scratches produced by the product during processing, and the other is the scratches produced by the logistics during the production process. mark.

6. There are debris in the base layer, which refers to the defects that the surface of the substrate is not cleaned during the surface treatment of the sheet metal shell, which is the main reason for the coating layer to fall off.

In summary, it is to identify whether there are defects in the processing of sheet metal shells, and mainly look at some aspects. If we have the above problems in the process of sheet metal shell processing, it means that there are certain defects in sheet metal shell processing. At this time, we need to deal with the causes of the defects in a targeted manner, so as to solve the defects, so as to better To ensure the quality of sheet metal shell processing.
