Every day, we come in contact with objects that are injection molded – one of the cornerstone technologies that define our modern world. Injection molding allows designers to create extremely complicated parts with relatively low part cost after a (usually expensive) initial investment in an injection mold.
Injection molds are often closely guarded trade secrets – Legos is said to bury worn-out molds in the concrete of its new buildings. However, since we are an open sourced project, working closely with our manufacturing parters, I am able to give you a behind-the-scenes look at how injection molds are built.
