Abstract
A compression mold having first and second steel plates. First and second frame members are attached to the first and second plates respectively and have a plurality of cavities for receiving replaceable half-molds. The mold further includes a plurality of first and second half-molds positioned within the cavities of the first and second frame members and having opposing top edges for contacting when the mold is closed. First and second rubber shims are positioned between the first and second plates and the first and second half-molds and have a first configuration before curing and a second configuration after curing in that position for positioning the corresponding, opposing half-molds such that their top edges contact each other fully when the mold is closed.
