Injection Molded Car

A car body taken from sketch and CAD to a machined mold plate and a molded part.

Aim

Design a car body that can be machined into a mold and molded, and document it so it can be inspected.

Tools
  • SolidWorks
  • Mastercam
  • 3-axis CNC mill
  • Injection molding
  • Concept sketching
Skills
  • Design for manufacture and assembly
  • Technical drawing with inspection balloons
  • CAM toolpath strategy
  • Cutting tool selection
  • Mold basics: gate, cavity, core
Outcome

A machined mold plate and a molded gray car, with a ballooned drawing of the part.

Mold cycle shown as sequence only, not process data.
Detail

Six rest-roughing and finishing operations step down from a large bull mill to a 1/16 in ball mill, and the gate is cut as its own step with the smallest tools.
