Abstract: The present disclosure provides a molding machine and a method of molding a part. The molding machine may include multiple molding systems (e.g., extruders) for pumping molten material into one or more mold cavities. The multiple molding systems may pump the same material or different materials into the one or more mold cavities. The multiple molding systems may be individually and/or collectively controlled. A method of molding a part may include pumping material into one or more mold cavities via multiple molding systems, ceasing pumping material into the one or more mold cavities when one or more pressures associated with the multiple molding systems are achieved, and releasing a molded part from the one or more mold cavities after the one or more pressures are achieved.
Abstract: 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.
