section 18 design of plastic gears 18.1 general considerations of plastic gearing plastic gears are continuing to displace metal gears in a widening arena of applications their unique characteristics are also being enhanced with new developments both in materials and processing in this regard plastics contrast somewhat dramatically with metals in that the latter materials and processes are essentially fully developed and therefore are in a relatively static state of development plastic gears can be produced by hobbing or shaping similarly to metal gears or alternatively by molding the molding process lends itself to considerably more economical means of production therefore a more in-depth treatment of this process will be presented in this section among the characteristics responsible for the large increase in plastic gear usage the following are probably the most significant 1 cost effectiveness of the injection-molding process 2 elimination of machining operations capability of
