I designed the car like I did because the top will help it make it down the track, and the bottom (with the weight) will help the car race faster.

SolidWorks CAD rendering of the vehicle concept. The CAD geometry will be used to create the cavities in the injection mold plate inserts. Wheels and a color scheme have been added for show.
SolidWorks rendering of the mold inserts. The mold geometry includes the cavities for the vehicle plus the runners and gates which allow the polymer melt to flow into the cavity during molding. The larger holes in the corners of the molds will be used to secure the inserts to the mold base. The mold geometry is ready to be imported into the NX CAM software to create a set of toolpath instructions for machining.
