How are LEGO bricks made, and what materials are used?

I've always been curious about how LEGO bricks are made and what materials are used. Could you explain the process of manufacturing LEGO bricks and the materials used in their construction? I'm interested in learning more about the production process, including how the plastic is melted and molded into different shapes and sizes, as well as the quality control measures in place to ensure that each piece is of the highest quality.

LEGO bricks are made from a type of plastic called acrylonitrile butadiene styrene (ABS). The manufacturing process involves melting the ABS plastic pellets and injecting them into molds to form the various shapes and sizes of LEGO pieces. The molds are cooled and the pieces are removed, then trimmed and inspected for quality.
