Abstract
A method for the application of a function element (10, 101) to a mouldable metal piece (12) using a high pressure moulding process, whereby the metal piece (12) is put under load by means of a fluid pressure on the side away from the supported function element (10, 101) and moulded in a moulding process around at least one section of the function element in the region of a radially inward running surface of the function element, facing away from the front face (18) of the function element (10, 101) in contact with the metal piece, to give an annular rabbet running radially inwards with an annular form, the function element being supported throughout said process. Said method is characterised in that during a second phase of the moulding process the annular rabbet is pressed flat between a moulding surface of a die and the surface of the function element running radially inwards. The invention further relates to an assembled component produced by means of said method and a die used to carry out said method.
