Cabinets ubiquitous sheet metal processing process, more or less there will be some problems, how to identify the sheet metal processing process defects, we have to share the experience to distinguish.
Common defects in the Sheet Metal Processing Electric Power Cabinet surface are debris at the grassroots level, serious color, surface scratches, coating off, lacquer, exposed substrate, powder, etc., which are currently the cabinet sheet metal processing of some common defects. '
1, the surface scratches are more complex and throughout the production process, but can be divided into two categories:
First, the product produced in the Sheet Metal Processing Electric Power Cabinet of scratches
Second, in the production process of logistics scratches.
2, the coating is mainly off the coating layer and the substrate of the binding force is not enough, the main means of detection of the impact of the impact test and grid test.
3, exposed substrate refers to the surface without coating, the main cause is leakage spray, large area scratches.
4, color is serious refers to the same surface color inconsistency, color difference of more than 1.
5, the base layer of debris is the surface treatment of the substrate surface is not dealt with clean the defects, it is the main reason for the coating shedding.
6, lacquer flow, the principle of powder generated roughly the same, but the paint is produced when the paint, the powder is sprayed when the production is due to excessive spray, too thick and produce defects.
