Abstract
Indicia creating patterns are placed in a mold assembly used for making seals. The molded seal body includes trimming entry surface indicia and trimming exit surface indicia to provide visual targets to use when setting up equipment to trim a waste portion from the finished seal . The indicia are sized such that a seal is considered properly trimmed if a portion, but not the entirety of the entry surface indicia and exit surface indicia remain on the finished seal at each point of trimming around the circumference of the seal body. Thus, one can quickly determine if a seal is properly trimmed.
