for manufacturing parts.  Plastic is forced from a
heated cylinder, under pressure, into the cavity
of a confined mold.  It changes state from liquid
to solid, and is ejected as a finished part.   
Injection molding is a production process.  
When alternate manufacturing methods and
materials are an option, injection molding
typically becomes economically viable at
around 1,000 pieces.
