Would you believe that a Lego piece released in the 1950’s can still be interlocked with a Lego piece created today despite difference in variations and design? Well, it is true and that is because Lego pieces are being created under a universal system. One of the most amazing about these bricks is that they can interlock easily and hold to each other firmly, but once you try to disengage it, it comes off easily. This is why sets such as the Lego grand emporium are so popular today.
The plastic used to manufacture a Lego brick is called acrylonitrile butadiene styrene (ABS). Before producing their products, Lego designers uses NX CAD/CAM/CAE PLM software to mould the plastics and see if they are precise and on an exact fit with each other. These sample moulds are called prototypes and once they are successfully built, then the company would know it can be released.
The plastics are moulded and heated on a 232 Celsius heat before being put on the moulds. These moulds are being checked for their weight and thickness to ensure everything is correct. Colours are being taken care as well because it is important to maintain the correct colour of the bricks for building purposes. After creating the bricks, they are packed and shipped to different locations for decoration purposes. Just for additional information, Lego produces at least 36 billion brick pieces per year and if everyone in the world will be given a Lego bricks, each person can have at least 62 bricks. If you are not amazed with that, then read this- Lego is the world’s number one manufacturer of rubber in the whole world with 306 million tiny rubbers produced every year.
So if you think Lego is an easy made business, you are wrong. Aside from the precision of design, it also requires effort to maintain high quality and correct combination in every package sent out to customers.
