Abstract
The invention relates to a method of providing a solenoid housing, including the steps of providing a solid cylinder of malleable material having a first part and a second part; reducing a diameter of the first part of the cylinder to be less than a diameter of the second part of the cylinder; compressing the second part in an axial direction toward the first part, resulting in a flattened disc generally perpendicular to the first part; raising at least a part of a perimeter of the flattened disc in a direction toward the first part for defining a raised wall; and wherein the first part, second part, and raised perimeter are all integrally connected as a single piece.

A method of providing a solenoid housing, comprising the steps of:
- providing a solid cylinder of malleable material having a first part and a second part;
- reducing a diameter of the first part of the cylinder to be less than a diameter of the second part of the cylinder;
- compressing the second part in an axial direction toward the first part, resulting in a solid, flattened disc approximately perpendicular to the solid, first part;
- cold forging an entire outermost perimeter of the flattened disc in a direction toward the first part for defining a solid, raised wall;
- extending the solid, raised wall to define a approximately annular recess having a depth;
- and
- wherein the first part, second part, and raised outermost perimeter are all integrally connected as a single piece.

- reducing a diameter of the first part of the cylinder to be less than a diameter of the second part of the cylinder;
- compressing the second part in an axial direction toward the first part, resulting in a solid, flattened disc with a first part side approximately facing towards the first part and a second part side approximately facing towards the second part;
- cold forging an entire outermost perimeter of the flattened disc in a direction toward the first part for defining a solid, raised wall;
- extending the solid, raised wall from the first part side in a direction approximately opposite the second part side;
- controlling a cross section of the flattened disc strength relative to a cross section of the raised outermost perimeter;
- orienting a plurality of grain lines of the flattened disc to be in a radial direction extending outwardly from a general center of the solid, flattened disc;
- and
- orienting a plurality of grain lines of the first part to be in an axial direction extending along a length of the solid, first part;
- and
- wherein the first part, second part, and raised outermost perimeter are all integrally connected as a single piece.
