Many product needs gear for moving function. There are lots of gear. it save much cost for make gear mold by exchange core and cavity.
The differences are quite fundamental. Machined gears are cut to size with specialized machinery designed specifically for the task. Molded gears are formed in gear cavities that are usually cut with wire Electrical Discharge Machines (EDM). These cavities are sized so that the molded gear will shrink to the proper size after molding. One cavity might be expected to form more than a million molded gears.
The gear mold is charged with the task of making one nearly perfect gear cavity and then processing each gear from that cavity within tolerance for every piece made. This is small but significant difference leads to many other variations.
