LEGO® bricks and elements are manufactured at the Group’s own factories in Denmark, Hungary, Czech Republic and Mexico.
During the moulding process, plastic is heated to 230-310C so it is the consistency of dough. It is then injected into moulds at a pressure of 25-150 tons, depending on which element is being produced. On average it then takes 5-10 seconds for the elements to cool and be ejected.
The moulds used in production are accurate to within five my (=0.005mm) and this accuracy means than only 18 elements in every million products fail to meet the high quality standard.
In 2011 more than 36 billion elements were made, equivalent to approximately 68,000 per minute or 1,140 elements every second. All LEGO elements are fully compatible, no matter when they were made during the period from 1958 until now or by which factory.
There are roughly 4,200 different elements in the LEGO range in 58 different colours. With elements available in a wide variety of different colours and decorations, the total number of active combinations is around 9,000.
