Injection Mold Factory Tour

Shenzhen Adventure Day 4

At this place we got to see them designing and making the molds. This was pretty crazy to me! Basically you can 3D-model your part and then ship it to them and they design a mold around it which has all the mechanical parts needed to make the mold. Once the design is there, they will CNC mill it out roughly. For finer details, they will do what’s called Electric Deposition, where they use a finely CNC’ed copper electrode in the mirror image of the design and repeatedly tap it onto the mold with a massive current running. This eventually cuts out the design layer by layer by blasting away the steel and copper.
