The main raw material is polycarbonate which comes in large bags shown below

The discs start out as grains of polycarbonate

The grains are first sent to the drying machine

The crystals are melted together into a liquid mass

The liquid mass is crammed into press-form using a stamper inside

Stamper is a metal plate with precise information. The one shown below is a movie which will be on the DVD

The liquid polycarbonate is turned into a disc at 250 degrees and the info is stamped on to it

The workpieces are then cooled
