The Lego Group began manufacturing the interlocking toy bricks in 1949. Supporting movies, games, competitions, and six Legoland amusement parks have been developed under the brand.
As of July 2015, 600 billion Lego parts had been produced.
Lego bricks from 1958 still interlock with those made in the current time, and Lego sets for young children are compatible with those made for teenagers.
Six pieces of 2x4 bricks can be combined in 915,103,765 ways.
Lego pieces can be assembled and connected in many ways, to construct objects; vehicles, buildings, and working robots.
Anything constructed can then be taken apart again, and the pieces used to make other objects.
Prototype moulds are sometimes built before the design is committed to mass production.
The ABS plastic is heated to 232 °C (450 °F) until it reaches a dough-like consistency.
The software allows the parts to be optimized by way of mould flow and stress analysis.It is then injected into the moulds at pressures between 25 and 150 tonnes, and takes approximately 15 seconds to cool.The moulds are permitted a tolerance of up to two micrometres, to ensure the bricks remain connected.The machines that manufacture Lego bricks have tolerances as small as 10 micrometres.Primary concept and development work takes place at the Billund headquarters, where the company employs approximately 120 designers.
In 1949 Lego began producing, among other new products, an early version of the now familiar interlocking bricks, calling them "Automatic Binding Bricks".
