It really depends on what type of parts and materials you are talking about.

Thermoforming is very popular for a lot of consumer goods. You basically take a sheet of plastic and press a mold into it. An example is TV dinner trays.

Blow molding is very popular for bottles. You start out with a peg of plastic and blow air into it and fill out a mold.

Many of the harder and more perminant plastics are injection molded. You inject plastic into a steel mold and then pull it apart.

Another is FRP – fiberglass reinforced plastic. You see this a lot in tub surrounds and boats. You start with a layer of fiberlass and either spray on or inject plastic.
