Lego brick is an old invention by now.
3
The first plastic brick was molded in 1949.
4
Since then, thousands of new and unique Lego elements have been developed.
5
Pick a Lego brick from a box today and it will fit with any brick that was molded decades ago.
6
This is the result of great precision and commitment for more than 50 years.
7
The LEGO Group has factories across the world.
8
But how do you produce hundreds of different types of bricks with such precision
9
and in a wealth of colors every single day?
10
And how do the Briggs find their way to the right boxes?
11
This is the story about how small pieces of plastic granulate are transformed into creative playsets.
12
A truck arrives with raw material at the factory.
13
A truck like this holds up to 28 tons of plastic granulate.
14
The granulate is blasted from the truck into tall silos where it is stored.
15
Different types of plastic granulate are used depending on the function of each Lego element.
16
The granulate is fed down a labyrinth of long pipes into the factory.
17
The pipes lead to the heart of the Lego factory, the molding area.
18
High-tech injection molding machines produce Lego elements 24 hours a day, seven days a week.
19
First the raw granulate is mixed with the dye.
20
Bricks are currently produced in over 50 different colors.
21
The colored granulate is then led into the molding machine.
22
Within no time the granulate is heated to between 230 and 310 degrees Celsius.
23
The plastic melts into a texture much like toothpaste.
24
With great force the paste is then fed into the mold.
25
Great forces must be controlled during this process.
26
The pressure can reach 29,000 psi.
27
In comparison, a car's tire pressure is 29 to 43 psi.
28
In the mould, the material is cooled in a matter of seconds, and out comes a new-born Lego brick as we know it.
29
Plastic waste from the molding machines is ground and recycled straight away.
30
Each mold can make one shape of Lego element at a time.
31
To make a different shape of element, the mold must therefore be replaced.
32
The unique molds are part of the secret behind the success of the Lego Group behind the success of the LEGO Group.
33
In each factory there's a department dedicated to regular cleaning and maintenance of the moulds.
34
The moulds are made with great accuracy, ensuring that all LEGO bricks always fit together perfectly.
35
The moulds are therefore handled with greatest care.
36
Each mould has a specific set of instructions, which among other things cover pressure, time and temperature.
37
Temperature tests and moulding tests are carried out to ensure the machine is programmed to perfection at each replacement of the moulds.
38
Samples are sent to the quality department, which measures such things as the durability and precision of the element.
39
It is ensured that the LEGO element is perfect.
40
AGV stands for Automatic Guided Vehicle.
41
Robots like these were introduced into the production as early as 1987.
42
When the box by the molding machine is full, these intelligent helpers replace it with a new empty box.
43
The AGV then takes the full boxes to the conveyor system.
44
A unique barcode identifies the contents of each box.
45
The boxes are shaken to even out the content, ensuring it takes up as little space as possible.
46
Now the lids can be closed.
47
This is where the journey of the boxes ends for now.
48
In High Bay warehouses up to 37 meters high, the boxes are ready to be collected.
49
When a specific LEGO element is required, the box is collected.
50
All registration and localization is entirely automated.
51
The boxes are then transported onwards from here.
52
Many elements are taken directly to the packaging lines, But not these little guys.
53
The minifigures must first get their own unique expression.
54
A machine can produce more than 7,000 torsos per hour.
55
Over half a billion minifigures are produced every year, making them one of the world's largest populations.
56
In the first part of the packaging process, counting machines ensure that elements are put in small production boxes.
57
One by one they're weighed and measured to secure the right numbers in each box.
58
The bricks to be included in just one bag in a complete Lego set are placed in rows of counting machines.
59
The content of each production box is then automatically put in a plastic bag.
60
The bags are dropped into open Lego boxes along with the building instructions and large special elements.
61
The most efficient packaging lines pack over 50,000 boxes every 24 hours.
62
Now the boxes are closed and sealed.
63
Here we have final LEGO boxes as we know them.
64
The LEGO boxes are packed for shipping and stacked onto pallets.
65
They are now ready for a long journey.
66
First stop of the journey is at one of the large distribution centres.
67
From here they are shipped to stores all over the world.
68
It is now up to children and adults to explore the fun and creative building experiences of the LEGO set.
69
Thank you.

À propos de cette leçon
Vous vous entraînez en anglais avec "LEGO Bricks In The Making" en utilisant la technique du Shadowing.
Qu'est-ce que la technique du Shadowing ?
Le Shadowing est une technique d'apprentissage des langues fondée sur la science, développée à l'origine pour la formation des interprètes professionnels. Le principe est simple mais puissant : vous écoutez de l'anglais natif et le répétez immédiatement à voix haute — comme une ombre suivant le locuteur avec un décalage de 1 à 2 secondes. Les recherches montrent une amélioration significative de la précision de la prononciation, de l'intonation, du rythme, des liaisons, de la compréhension orale et de la fluidité.
