Sheet metal processing of home appliances

The aluminum sheet metal processing plant checks the standard air pressure and ambient humidity in the drying room on time. Salvage method: sanding after drying treatment, spraying intermediate paint again in the affected area, sanding and then spraying paint. There are many sheet metal processing plant processes, and according to different sheet metal parts commodities, different processing procedures are selected, which generally include shearing, punching/cutting/composite type, folding, welding, riveting, piecing, forming (such as vehicle body), spraying, etc. The provisions of different processes are strictly quality and strict control, but inevitably some problems will occur, as in the case of spraying in sheet metal processing plant, the surface will appear However, there are inevitably some problems, such as the surface of the sheet metal fabrication plant may show granules and orange peel, which seriously affect the beauty. Particulate matter (stains and floating dust) definition: there are particles protruding from the surface of the plating.

Formation reason: the body surface is not moderately cleaned before painting. The filter has been removed and replaced at that time. Paint booth standard air pressure is too low. Painters dressed under appropriate, unclean clothing pants.

Prevention method: New energy sheet metal processing must clearly clean the body with cleaning liquid and clearly clean the body surface with sticky dust cloth before painting.
