Abstract
A system and method for forming a polymeric molding. A mold component includes a transmissive portion for passing curing energy such as UV light into the mold cavity. A masking collar is engaged around the transmissive portion to block curing energy from exposing and curing polymeric material outside of the region underlying the transmissive portion.
