Sheet metal component manufacturing method for e.g. ventilation cooler, involves producing sheet metal blank made of sheet metal, and shaping coated sheet metal blank for producing sheet metal component

摘要

The method involves producing a sheet metal blank (1) made of a sheet metal that is provided with a coating (2) for heat insulation, where the sheet metal blank exhibits a base (5) and four side walls (6-9). A coated sheet metal blank is shaped for producing a sheet metal component. The coating is made of sealing material, elastomer, foam material and/or thermoplastic, and is produced as a flexible coating, where the coating has coating thickness of 0.5 to 20 mm.
