Abstract: A method for connecting an aluminum die-cast part to another part. The aluminum die-cast part has a circular shoulder and a collar that projects upwards, whereas the other part comprises a flat contact piece that is designed to lie on the shoulder. The collar projects above the contact piece. The contact piece is pressed onto the shoulder by a deformation fo the collar, the collar being completely deformed about its circumference.

Abstract: In a method of securing a rod-shaped part in a surrounding holding member, a flat holding member is fabricated with opposite side edges that are formed with elements configured for interlocking engagement. The side edges of the holding member are bent upwards, and the holding member is then shaped into a cross section in accordance with the cross section of the rod-shaped part. After inserting the rod-shaped part into the holding member; the holding member is press-fitted about the rod-shaped part.

Abstract: A housing for a small electrical machine, particularly a small electric motor, forms a part of the magnetic circuit of the same and is composed of a cylindrical wall of a magnetoconductive material and a sheet-metal strip which is also constituted by a magnetoconductive material and is bent about the cylindrical wall. A method of manufacturing of the housing includes the steps of bending a sheet-metal band so as to form the cylindrical wall, and bending the sheet-metal strip about the thus-bent sheet-metal band so that the latter serves as a mandrel. The sheet-metal band may be bent on a primary mandrel and temporarily retained on the latter so that the sheet-metal strip is then bent about the band when the latter is still retained on the primary mandrel. End portions of the sheet-metal band and the sheet-metal strip may be connected with one another along the same generatrix of the cylindrical wall.
