Although the quality and detail of parts manufactured from both processes are similar, there are a few differences. The tooling for thermoformed parts is much less expensive. This is because injection molding tools require a cavity and a core, while the tooling used in the thermoforming process is one-sided. Because of this, parts get to production quicker. Another difference is that the tooling used in thermoforming can be easily and affordably modified in the event of a product design change
