Rapid tooling developed from the rapid prototyping technology is a new method and technology of mold making, and this paper mainly studies the composite aluminum-filled epoxy (CAFÉ) mold，which is one of the rapid bridge toolings, applied to thermoforming of the plastic parts. The material formula of the CAFÉ mold with E51 as matrix is developed, and using the formula we have made the CAFÉ mold for the back shell of a cell phone charger, which is installed at the injection molding machine to do the test and finally successfully obtain the polypropylene sample. In addition, the process of making the CAFÉ mold is described in detail in the paper.
