How is a Lego block made?

It is very popular as an assembly toy, and it is a LEGO block that can make various things. You can see how the block itself is made with photos and movies.

Details are as follows. The Lego block produces 15 billion parts each year. The material of the block is a granule of synthetic resin called acrylonitrile butadiene styrene (ABS). It is also a synthetic resin with high strength and impact resistance, which is also used for automobile interior.

Put this grain in a molding machine, melt at 232 degrees Celsius temperature and pour into mold. Then it compresses with a force of 25 tons to 150 tons and makes it into a block shape. It seems that there are as few as 18 defective products in the Lego block per million, but it seems to be the power of this strong power.
