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. |
