Perishables perform the actual cutting, smoothing, and shining of the mold. Mechanical equipment may make the perishables work faster, but it is the perishables that are doing the polishing work. From the coarsest files and discs through stones and emery, and finally to the fine diamond compounds, all perishables work together to refine the molding surface to conform to the customer’s specifications.
The most common perishable products used in mold polishing are presented on the following pages.
