1. A method of overmolding a substrate having a first side, a second side and a central hub opening, comprising the steps of:

  • placing a plurality of support feet on only said first side of said substrate;

    placing said substrate in an injection mold having at least one injection hole in a first side of said injection mold and having a continuous second side opposite said first side, said first side of said substrate being toward said first side of said injection mold and said second side of said substrate being toward said second side of said injection mold;

    filling said mold through said at least one injection hole in said first side of said injection mold with a molding material with said molding material enveloping said first side and enveloping said second side of said substrate though said central hub opening with a force exerted on said first side of said substrate by a flow of said molding material being about the same as a force exerted on said second side of said substrate by said flow of said molding material during said filling step; and

    removing said substrate having been overmolded from said injection mold.
