Lee mold blocks are made from aluminum because of the exceptional molding qualities. The mold cavities are lathe bored for unmatched roundness and size control. Lee Six Cavity Commercial Quality Molds are made for heavy-duty volume production. The mold and blocks have steel bushing and alignment pins for lasting precision. They include a cam operated sprue plate to eliminate the pounding common to ordinary molds. The sprue plate is hard anodized and held down with wave washers at each end. Handles not included.
