HOW IT’S DONE

-

Sound engineers produce the lacquer or copper discs that are electropla­ted to make nickel copies that will act as top and bottom moulds. Those discs – or stampers – go into our presses. We sandwich extruded polyvinyl chloride, copolymer preforms in-between them, and heat and compress them. Finally, we cure the finished product and trim the excess material.
