Abstract
Although injection molding includes extreme conditions, an RFID device may be over-molded by injection molding. A syringe includes a barrel having a first and second axial ends, the barrel defining a cavity therein; a plunger configured to be received in the cavity and define with the barrel a chamber for holding a fluid, the plunger being axially moveable within the barrel for increasing and decreasing the volume of the chamber thereby respectively forcing fluid into or out of the chamber; and a plunger seal, also known as a “syringe stopper” for sealing between the plunger and the barrel, the plunger seal including an RFID device for identifying the syringe. The plunger seal may be made by injection molding.
