Abstract:
A process for overmolding tubes comprising the steps of:inserting a tube of a first polymer, having an inner diameter, at least partially into a mold and at least partially onto a cylindrical mandrel, the mandrel having a base and a tip, an outer diameter of said mandrel dimensioned so as to allow the inner diameter of the tube to slide thereon, said mold containing a void for receiving a second polymer, the void co-acting with the mandrel and the tube to define an overmolding shape;injection molding the second polymer over the tube and the mandrel in the void of the mold; andcrosslinking the first and second polymers independently to an initial degree, andindependently crosslinking said polymers to a higher final degree.
