Most parts are shipped “as molded.” Some parts however require minor cleaning, normally accomplished using one of several types of tumblers.

Gate marks can also be removed by buffing, grinding or trimming.

Tapping, drilling, insertion, assembly, bonding, decorating or other secondary operations are sometimes used to facilitate the production process. In order to decrease mold complexity or improve production throughout, for example, a part feature might be more easily added after molding.
