Abstract
A process for creating a stop surface on a plunger rod of a syringe is disclosed. The process includes the step of providing a preformed or molded plunger rod, and the step of forming a radially-extending deformation on the molded plunger rod. The presently disclosed in-line process allows for the use of a single molding rod to form plunger rods having one or more selectively located stop positions.
