Model Maker’s How-to: Casting Cars

KiwiMill model makers recently designed a car model to be used for a sales display. The models will be used to showcase automotive paints for Hyundai. We chose to cast these from a carved resin master made from our original computer drawings.

A generic car body was created in Rhino 3D by one of our designers.

A  CNC milled resin master was created from this drawing.

A negative mold  of the core was made from the master.

 This core was inserted in the mold to create a hollow space in the cars when cast.

 Three molds were made to cast the cars.

130 castings were created.
