The Making of a LEGO Brick

Let’s hear it for LEGO! Forty-eight years after they were introduced, LEGO toys are still much beloved by children and parents alike for their bright colors, durability, and the amount of imagination they inspire during play. Compared to the high-tech toys of today, LEGO bricks look exceedingly simple. But their precise production process is nothing to scoff at. Each LEGO brick must have that perfect grasp — strong enough to hold onto another brick but easy enough for a child to pull apart. The production of LEGO bricks is so accurate that only 18 out of 1 million LEGO elements produced is considered defective. It’s an astonishing number, considering that 15 billion LEGO components are made every year. We take a look at how classic LEGO bricks are made.
