Abstract
A method of forming a threaded bore in a compression molded part comprises: positioning at least one rotatable threaded shaft in a mold cavity during compression molding of a part; rotatably driving the at least one threaded shaft for unthreading the at least one threaded shaft from the part; and pushing the at least one threaded shaft away from the mold cavity once the at least one threaded shaft is unthreaded from the part.
Claims2
A method of forming a threaded bore in a compression molded part, comprising:
