News Title: How to Identify the Defects of Sheet Metal Shell Machining Parts?

怎样辨别钣金外壳加工件缺陷的方法?
News details
Common defects on the surface of sheet metal processing cabinets include debris at the base layer, serious color difference, surface scratches, coatings falling off, paint flow, exposed substrates, powder deposits, etc. These are some of the current common problems in cabinet sheet metal processing. defect. The following editor from Shandong Guermei explains how to identify the processing method of sheet metal cabinets:
1. The causes of surface scratches are more complex and run through the entire production process, but they can be roughly divided into two categories:
是产品在加工时产生的划痕 ① 、 It is the scratch generated during the processing of the product
是在生产过程中物流产生的划痕。 ②, is the scratches generated by logistics in the production process.
2. The peeling 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-section test.
3. Exposed substrate refers to the absence of a coating on the surface. The main causes are missing spray and large area scratches.
4. Severe color difference means that the color of the same surface is inconsistent, and the color difference value exceeds 1.
5. Debris in the base layer refers to the defects caused by the surface of the substrate being not cleaned during the surface treatment. It is the main reason for the coating layer to fall off.
6. The principle of the paint flow and powder accumulation is roughly the same, except that the paint flow is generated when spraying paint and the powder accumulation is generated when spraying plastic. Both are caused by excessive spraying and thick coating.
