Component of a domestic appliance comprising micro-indentations, pressing tool and manufacturing method for the component

A domestic appliance comprising:

• a component comprising a sheet metal part formed from a piece of sheet metal, the sheet metal part having a first sheet metal surface and a second sheet metal surface opposing the first sheet metal surface,
• wherein a regular arrangement of first micro-indentations is provided on the first sheet metal surface of the sheet metal part, each first micro-indentation having a depth (d) perpendicular to the first sheet metal surface of not less than 40% of a sheet metal thickness (t) of the sheet metal part,
• wherein a regular arrangement of second micro-indentations is provided on the second sheet metal surface of the sheet metal part, each second micro-indentation having a depth (d) perpendicular to the second sheet metal surface of not less than 40% of the sheet metal thickness (t) of the sheet metal part,
• wherein the first micro-indentations provided on the first sheet metal surface are arranged in a staggered configuration with respect to the second micro-indentations provided on the second sheet metal surface, and
• wherein a regular arrangement of micro-protrusions is provided on the second sheet metal surface of the sheet metal part, each micro-protrusion corresponding in position and form to one of the first micro-indentations.
