A pair of substantially opposed mating surfaces are joined to each other and sealed in place by means of an electrically-conductive member which is placed in proximity to the mating surfaces. The system includes a plurality of stations for receiving, handling and processing the drug delivery device so that the prescribed dosage of medication is delivered to the drug delivery device and a transporting device that receives and holds more than one drug delivery device and moves the drug delivery devices in a controlled manner from one station to another station. In the latter position, the TPA blocks movement of the lance and provides a semi-circular stabilizing cradle in conforming contact with the terminal body to protect it against rocking motion while at the same time allowing rotation of the terminal about its own axis or symmetry. In addition, the bonding structures have smoother join profile and planar joint plane.
