Micro molding refers to injection molding of parts weighing a fraction of a gram, and it is becoming a sizeable opportunity for molders who serve the electronics, medical, telecommunications, and automotive market sectors. Some of the new poppy-seed-sized parts being molded today include gears and gear housings, hearing aids, molded interconnect devices (MIDs), bobbins, switches, sensors, lenses, catheters, gaskets, rollers, and fiber-optic components. These minute parts have even tinier critical features, such as pinholes, pins, channels, and snap-fit latches.
