Abstract
A method for position at least one pair of opposing half-molds in a compression mold that has opposing plates that are compressible towards each other. The method includes placing a shim of a curable material between a first one of the plates and at least one of the half-molds. The mold is closed by compressing the plates towards each other to align and fully contact opposed surfaces of the opposing half-molds in an aligned position. Closing the mold also deforms the shim. The shim is cured in the closed mold to retain the half-molds in the aligned position relative the plate to which they are mounted once the mold is opened. A frame member is preferably attached to the plate, and the half-molds are placed within cavities in the frame member such that half-molds can move vertically therein, but are retained laterally.
