The Engineer Guy Bill Hammack illustrates the process of plastic injection molding and how it revolutionized manufacturing. Hammack starts the video with the history of celluloid plastic developed by John Wesley Hyatt to replace ivory in billiard balls, which led to the first simple injection molding machine.
The video also pays special attention to the creation of LEGO bricks and how their process differs from typical injection molding. Hammack also shares a few other videos that get even more in-depth into the process.
