  2. Answers below Just in case you thought I was being facetious. 1) There's a very thin film of plastic. What's odd about the process is that for a plastic process its done at much higher temperature than injection molding so that it sticks to the paper/cardboard. Normally polyethylene and polyethylene/polypropylene mixes are moulded at 160-180℃ while for paper coating its 300-320 2) Because reflectors have to deal with heat from the light bulbs they were traditionally made from thermoset plastics which look and feel a bit like bread dough. Its pushed into the die where it is HEATED then cooled. The shiny surface is created by first spraying the front side in a lacquer that's UV cured and then under vacuum has a layer of Aluminum about 50-200 atoms thick embedded in the lacquer. Its the lacquer that makes one side shiny and the other dull grey. 3) Copper like many metals is first extracted from the ore using acid leaching. Aluminum does not dissolve from the bauxite using acids and it is instead done with caustic at temperature and pressure. The process is known as the Bayer Process and yes it was by a member of the Bayer family now famous for pharmaceuticals. 4) Copper unlike most metals work hardens as you bend and flex it so it need to be softened through the opposite process to the quench hardening you see on the sword & knife channels. It differs from tempering. Annealing unlike tempering aims to make the metal as soft as practical while tempering aims to specifically keep some hardness while reducing brittleness. To see examples of these processes I recommend watching the sword & knife channels for hardening and tempering and the hobbyist channels making things like model steam engines for annealing. the channel Blondihacks is currently building a model steam engine made from copper. 5) I'd expect that any mechanical engineer knows the difference between a lathe and a mill. Look at what is rotating in the main spindle. A lathe has the part held to the spindle and rotates while the tool is moved in 2 or more axis to shape the part. A mill has the tool mounted in the spindle and it rotates while the part is held to the table and moved around in 2 or more axis to make the part. Where it gets confusing is that it is possible to use a mill as a lathe and a lathe as a mill.
