Insert and seat elastomeric stoppers/plungers into vials, cartridges and syringes

Before capping, sterile containers must receive rubber/elastomeric closures: vial stoppers pressed to the correct depth, syringe plungers/pistons inserted to a target position, cartridge stoppers seated for container-closure integrity. A robot must press a compliant elastomeric component into a rigid glass bore to a precise seating depth while accommodating dimensional variation in both the rubber and the glass. The task sits immediately after filling and gates sterility/closure integrity for the whole unit. It is hard because the stopper is deformable and the glass is fragile, so insertion force must be controlled to seat fully without cocking the stopper, over-compressing it, or cracking the bore, and the seated depth must be confirmed. This is a standard but contact-critical step across AbbVie's vial and prefilled-syringe lines. We identified this through our own research; we have not confirmed the specifics with the customer directly. This page is our researched read — a starting point for that conversation.
