Abstract: An injection molding system includes a cavity assembly and a core assembly. The core assembly includes a core plate, a core skeleton secured to the core plate, and a removable core body insert defining a mold shape, secured to the core skeleton. The cavity assembly includes a core plate with a circular groove and a gate pad disposed in the groove, providing an entry point for liquefied resin material. The cavity assembly further includes a cavity insert disposed on the gate pad, forming an inner cavity for receiving liquefied resin material via the gate pad and for receiving the removable core body insert of the core assembly. The core assembly further includes a cavity skeleton with a circular opening for providing access to the inner cavity, disposed over the cavity insert and the gate pad, and secured to the cavity plate.
