It’s one of the most common manufacturing processes in the world, responsible for a huge number of the products you own. Yet most people don’t know how it works.

How do you produce plastic into the millions of products produced daily? By squeezing them into the right shape in a process called Plastic Injection Molding.

Without it, many innovations would never be able to reach the scale, volume and prices to make them viable.

In the excellent video above, Bill “Engineerguy” Hammack takes us through the surprisingly complicated yet efficient process of turning shapeless plastic pellets into everyday objects.

You might also learn how this process may have saved elephants from extinction.

So whether you’re figuring out what it’s going to take to turn your idea into an innovation, or you just get a new perspective on where the products you buy come from, you’ll now know how it works.
