The following wood frame was created to test the expansion range of the car jack early in the design process. From this prototype, we were able to determine the clearance needed for opening the mold and the length of the vertical frame pieces.
The following small mold was created to test the machining of the mold and melting properties of the plastic. This small scale mold is roughly 6.5x5 inches compared to the final mold size of 15x15 inches. The mold was machined out of steel, the same material as the actual mold.
