摘要：
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.
摘要（中）：
虽然注射成型包括极端条件，但RFID装置可以通过注塑成型而被超模塑。 注射器包括具有第一和第二轴向端部的筒，所述筒在其中限定空腔; 柱塞，其构造成容纳在所述空腔中并且与所述筒一起限定用于保持流体的室，所述柱塞在所述筒内可轴向移动以增加和减小所述室的体积，从而分别迫使流体进入或离开所述室; 以及柱塞密封件，也称为用于密封柱塞和筒体之间的“注射器塞子”，柱塞密封件包括用于识别注射器的RFID装置。 柱塞密封件可以通过注射成型制成。
