Abstract
A method for manufacturing housing or control-components parts of metal including the steps of: manufacturing a housing or control-component part ( ) as a forged or cast blank ( ), stamping a recess ( ) in the blank for an indicator insert with a stamping die in a stamping device, thereby creating a protrusion ( ) on a back wall surface ( ) of the part in the stamping direction, constricting the recess ( ) with peeled protrusions of the peripheral walls ( ) defining the recess ( ), injecting a transparent plastic ( ) into the recess ( ) and, if applicable, into a mold connected with the recess ( ) for forming a collar ( ) on a front wall surface ( ) in the stamping direction, and ablating the back wall surface ( ) and the protrusion ( ) by a fixed thickness amount ( ), which results in exposure of the recess ( ) and of the transparent plastic ( ).
