Techniques in The Manufacturing Of Lego

Right from 1963, lego 42056 pieces have been made and manufactured from a very strong and resilient plastic that is known to be acrylonitrile butadiene. When it was exactly September 2008, the creative Lego engineers began to use some modern and relevant software in the world of engineering and technology in other to suit the model or prototype of the element they had in mind. Such software include: NEX CAD, CAE, CAM, and PLM. This software makes the parts of the Lego to be adequately optimized by the way of stress analysis and mould flow. The prototype mould is usually built just before the company launch into the design of mass production. 

The plastic called ABS used is first heated up to a temperature of about 232 ⁰C which is (450 ^oF) until it get to point of dough-like consistency. Then it will be injected into that moulds at a particular pressure between 25 and 150 tones. This will then take about 15seconds to get cooled. In the process of manufacturing this lego 42056, there is allowance or permission for the moulds to reach up to 2 micrometers in other to make the bricks stay connected. The output of the moulds is inspected by a human inspector to ensure thatany significant variation in thickness or colors is totally eliminated. Based on this experience gained overtime by the Lego Group, it has been noticed and affirmed that out of millions of bricks made; just about eighteen usually fail to meet the required standard. The Lego factory usually carry out the recycling of all of their plastics, only one percent is wasted during manufacturing process and remained unusable afterward.

 In a situation whereby those plastics cannot be re-used in the process of lego 42056 bricks, it can be processed again and get them sold to other industries that can easily make use of them.
