ABSTRACT:
A method of making a mold for a given object includes forming a wire stack of elongated wire elements and aligning first ends of the wire elements to define a first end surface of the stack, displacing selected wire elements with respect to the first end surface of the stack by determined amounts in the longitudinal direction of the elements according to a shape of the object to be molded, and then fixing the wire elements of the stack from movement relative to one another after the wire element displacing step. A mold surface for the given object is thus defined according to the first end surface of the wire stack.
