There’s a good chance your brain’s already checked out on this shortened work week. But if you can still muster a thought process or two, you won’t be disappointed by Bill Hammack’s—aka engineerguy’s—latest video which explains the brilliant engineering behind the process of plastic injection molding.
If you take a quick look around your desk, you can probably find countless gadgets and other objects that were made using the process of plastic injection molding—possibly even the computer you’re viewing this on. The manufacturing industry is completely reliant on the process at this point, especially when it comes to toys designed to survive the rigors of playtime.
To mass produce its plastic bricks on an epic scale, Hammack explains how Lego has actually cleverly modified its plastic injection machines to both speed up the process, and produce toys with few of the telltale signs of the molds used. Who would have thought those studded bricks had such an impressive back story? [YouTube]
