Abstract: A syringe includes a barrel having a proximal end, a distal end, and a sidewall extending substantially circumferentially between the proximal end and the distal end along a longitudinal axis. The barrel is formed from an injection molding process including aligning a mold die defining an internal shape of the barrel in a molding cavity defining an external shape of the barrel, the molding cavity defined by first and second mold sections. Each mold section includes at least one gate adapted to control the flow of a molding material into the molding cavity. The gates of each mold section are opened to permit the first and second melt streams of molding material to fill the molding cavity surrounding the mold die, where the molding material takes the shape of the molding cavity.
