Abstract:
1. A process for overmolding a curvilinear rigid or semi-rigid polymer having a first profile, a radial angle of curvature (R c ), a radial angle of curvature radius (R), and a circumferential radial segment (R s ) onto a second profile, said second profile having an internal radius (R p ) comprising the steps of: assembling a split mold having at least one channel and a mold cavity, said channel in communication with said cavity; inserting said second profile into said at least one channel and at least partially into the cavity; inserting a curved core pin into the mold cavity and at least partially into said second profile; injecting a polymeric material into the split mold and said mold cavity thereby overmolding onto at least a portion of the second profile to form said overmolded first profile having a durometer ranging from approximately 35 Shore D to 95 Shore D inclusive; removing said core pin and the two profiles from the split mold; extracting said core pin from the first profile along said radial angle of curvature of said core pin and said first profile; wherein said radial angle of curvature (R said radial segment (R wherein R is greater than or equal to twice R as said durometer of said overmolded profile increases from 35 Shore D to 95 Shore D, said radial segment (R
